ISD5008 Single-Chip Voice Record/Playback Device 4-, 5-, 6-, and 8-Minute Durations Preliminary Datasheet ISD5008 PRODUCT SUMMARY The ISD5008 ChipCorder product is a fully-integrated, single-chip solution which provides seamless integration of enhanced voice record and playback features for digital cellular phones (GSM, CDMA, TDMA, PDC, and PHS), automotive communications, GPS/navigation systems, and portable communication products. This low-power, 3volt product enables customers to quickly and easily integrate 4 to 8 minutes of voice storage features such as one-way and two-way (full duplex) call record, voice memo record, and call screening/answering machine functionality. Like other ChipCorder products, the ISD5008 integrates the sampling clock, anti-aliasing and smoothing filters, and the multi-level storage array on a single-chip. For enhanced voice features, the ISD5008 eliminates external circuitry by also integrating automatic gain control (AGC), a power amplifier/speaker driver, volume control, summing amplifiers, analog switches, and a car kit interface. Input level adjustable amplifiers are also included, providing a flexible interface for multiple applications.

The ISD5008 device is designed for use in a microprocessor- or microcontroller-based system. Address, control, and duration selection are accomplished through a Serial Peripheral Interface (SPI) or Microwire Serial Interface to minimize pin count. Recordings are stored in on-chip nonvolatile memory cells, providing zero-power message storage. This unique, single-chip solution is made possible through ISD's patented multilevel storage technology. Voice and audio signals are stored directly into solid-state memory in their natural, uncompressed form, providing superior quality voice and music reproduction.

Increasing the duration decreases the sampling frequency and bandwidth, which affects sound quality. Table 1 compares filter pass band and product durations. One of the benefits of ISD's ChipCorder technology is the use of on-chip nonvolatile memory, which provides zero-power message storage. The message is retained for up to 100 years (typically) without power. In addition, the device can be re-recorded over 100,000 times (typically). The speech samples are stored directly into on-chip nonvolatile memory without the digitization and compression associated with other solutions. Direct analog storage provides a natural sounding reproduction of voice, music, tones, and sound effects not available with most solid-state solutions. 1.4 1.2 DURATION To meet end system requirements, the ISD5008 device is a single-chip solution which provides from 4 to 8 minutes of voice record and playback, depending on the sample rates defined by customer software.

The ISD5008 is configured to operate as a peripheral slave device with a microcontroller-based SPI bus interface. Read/Write access to all the internal registers occurs through this SPI interface. An interrupt signal (INT) and internal read-only Status Register are provided for handshake purposes. 1.5 PROGRAMMING The ISD5008 series is also ideal for playback-only applications, where single or multiple message Playback is controlled through the SPI port. Once the desired message configuration is created, duplicates can easily be generated via an ISD or third-party programmers. For more information on available application tools and programmers please see the ISD web site at www.isd.com. 1 ISD5008 Product 2 PIN DESCRIPTIONS 2.1 DIGITAL I/O PINS SCLK (Serial Clock) The SCLK is the clock input to the ISD5008. Generated by the master microcontroller, the SCLK synchronizes data transfers in and out of the device through the MISO and MOSI lines. Data is latched into the ISD5008 on the rising edge of SCLK and shifted out on the falling edge. SS (Slave Select) This input, when LOW, will select the ISD5008 device. MOSI (Master Out Slave In) MOSI is the serial data input to the ISD5008 device. The master microcontroller places data to be clocked into the ISD5008 device on the MOSI line one-half cycle before the rising edge of SCLK. Data is clocked into the device LSB (Least Significant Bit) first. OVF Flag. The overflow flag indicates that the end of the ISD5008's analog memory has been reached during a record or playback operation. EOM Flag. The end of message flag is set only during playback, when an EOM is found. There are eight possible EOM markers per row. RAC The RAC pin remains HIGH for 109.38 sec and stays LOW for 15.63 sec under the Message Cueing mode. See Table 15 Timing Parameters for RAC timing information at other sample rates. When a record command is first initiated, the RAC pin remains HIGH for an extra TRACLO period, to load sample and hold circuits internal to the device. The RAC pin can be used for message management techniques. XCLK MISO (Interrupt) INT is an open drain output pin. The ISD5008 interrupt pin goes LOW and stays LOW when an Overflow (OVF) or End of Message (EOM) marker is detected. Each operation that ends in an EOM or OVF generates an interrupt, including the message cueing cycles. The interrupt is cleared the next time an SPI cycle is completed. The interrupt status can be read by a RINT instruction that will give one of the two flags out the MISO line. 2 (External Clock Input) (Master In Slave Out) MISO is the serial data output of the ISD5008 device. Data is clocked out on the falling edge of SCLK. This output goes into a high-impedance state when the device is not selected. Data is clocked out of the device LSB first. INT (Row Address Clock) RAC is an open drain output pin that marks the end of a row. At the 8 kHz sample frequency, the duration of this period is 200 ms. There are 1,200 rows of memory in the ISD5008 devices. RAC stays HIGH for 175 ms and stays LOW for the remaining 25 ms before it reaches the end of the row. The external clock input for the ISD5008 product has an internal pull-down device. Normally, the ISD5008 is operated at one of four internal rates selected for its internal oscillator by the Sample Rate Select bits. If greater precision is required, the device can be clocked through the XCLK pin as described in Table 2. Because the antialiasing and smoothing filters track the Sample Rate Select bits, one must, for optimum performance, change the external clock AND the Sample Rate Configuration bits to one of the four values to properly set the filters to the correct cutoff frequency as described in Table 3. The duty cycle on the input clock is not critical, as the clock is immediately divided by two internally. If the XCLK is not used, this input should be connected to VSSD.

The direct path to the ANA OUT MUX has a gain of 6 dB so a 208 mVp-p signal across the differential microphone inputs would give 416 mVp-p across the ANA OUT pins. The AGC circuit has a range of 45 dB in order to deliver a nominal 694 mVp-p into the storage array from a typical electret microphone output of 2 to 20 mVp-p. The input impedance is typically 10 k.

It can be switched (by the SPI bus) to the speaker output, the array input or to various other paths. This pin is designed to accept a nominal 1.11 Vp-p when at its minimum gain (6 dB) setting. There is additional gain available in 3 dB steps controlled from the SPI bus, if required, up to 15 dB.

Differential ISD 5 ISD5008 Product ANAOUT+/- (Analog Outputs) This differential output is designed to go to the microphone input of the telephone chip set. It is designed to drive a minimum of 5 k between the "+" and "-" pins to a nominal voltage level of 700 mVp-p. Both pins have DC bias of approximately 1.2 VDC. The AC signal is superimposed upon this analog ground voltage. These pins can be used single-ended, getting only half the voltage. Do NOT ground the unused pin. 2.3 POWER AND GROUND PINS VCCA, VCCD (Voltage Inputs) To minimize noise, the analog and digital circuits in the ISD5008 device uses separate power busses. These +3 V busses lead to separate pins. Tie the VCCD pins together as close as possible and decouple both supplies as near to the package as possible. VSSA, VSSD (Ground Inputs) AUX OUT (Auxiliary Output) The AUXOUT is an additional audio output pin, to be used, for example, to drive the speaker circuit in a "car kit." It drives a minimum load of 5 k and up to a maximum of 1 Vp-p. The AC signal is superimposed on approximately 1.2 VDC bias and must be capacitively coupled to the load. SP+, SP- (Speaker+/-) This is the speaker differential output circuit. It is designed to drive an 8 speaker connected across the speaker pins up to a maximum of 23.5 mW power. This stage has two selectable gains, 1.32 and 1.6, which can be chosen through the configuration registers. These pins are biased to approximately 1.2 VDC and, if used single-ended, must be capacitively coupled to their load. Do NOT ground the unused pin. ACAP The ISD5008 series utilizes separate analog and digital ground busses. The analog ground (VSSA) pins should be tied together as close to the package as possible and connected through a lowimpedance path to power supply ground. The digital ground (VSSD) pin should be connected through a separate low-impedance path to power supply ground. These ground paths should be large enough to ensure that the impedance between the VSSA pins and the VSSD pin is less than 3 . The backside of the die is connected to VSSD through the substrate resistance. In a chip-onboard design, the die attach area must be connected to VSSD. (AGC Capacitor) This pin provides the capacitor connection for setting the parameters of the microphone AGC circuit. It should have a 4.7 F capacitor connected to ground. It cannot be left floating. This is because the capacitor is also used in the playback mode for the AutoMute circuit. This circuit reduces the amount of noise present in the output during quiet pauses. Tying this pin to ground gives maximum gain; to VCCA gives minimum gain for the AGC amplifier but will cancel the AutoMute function. 6 Voice Solutions in SiliconTM ISD5008 Product Figure 4: ISD5008 Series TSOP and PDIP/SOIC Pinouts ISD5008 ISD5008 28-PIN TSOP 3 PDIP/SOIC INTERNAL FUNCTIONAL BLOCKS Figure 5: Microphone Amplifier * 6 dB FTHRU AGC AGC Microphone MIC+ (300 mVp-p Max) MIC- AGPD 0 1 1 (AGPD) Power Up Power Down To AutoMute ACAP (Playback Only) * Differential Path 15 14 13 VLS1 VLS0 VOL2 ISD 12 11 10 9 VOL1 VOL0 S1S1 S1S0 8 7 6 5 S1M1 S1M0 S2M1 S2M0 4 3 2 1 0 FLS0 FLD1 FLD0 FLPD AGPD CFG1 7 ISD5008 Product Figure 6: AUX IN and ANA IN 1.0 / 1.414 / 2.0 / 2.828 Car Kit AUX IN AUX IN AMP AUX IN AMP AXPD 0 1 1 (AXPD) Power Up Power Down 2 (AXG1, AXG0) .625 /.883 / 1.25 / 1.767 Chip Set ANA IN AXG1 0 0 1 1 ANA IN AMP AXG0 0 1 0 1 Input Gain 1 1.414 2 2.828 0TLP Input Level .694 .491 .347 .245 ANA IN AMP AIPD 0 1 1 (AIPD) Power Up Power Down 2 (AIG1,AIG0) AIG1 0 0 1 1 8 15 14 AIG1 AIG0 AIPD 13 12 11 10 9 AXG1 AXG0 AXPD INS0 8 7 6 5 AOS2 AOS1 AOS0 AOPD AIG0 0 1 0 1 4 Input Gain 0.625 0.883 1.250 1.767 3 OPS1 OPS0 2 0TLP Input Level 1.11 .785 .555 .393 1 0 OPA1 OPA0 VLPD CFG0 Voice Solutions in SiliconTM ISD5008 Product Figure 7: ISD5008 Core (Left Half) SUM1 SUMMING AMP INPUT SOURCE MUX AGC AMP SUM1 AUX IN AMP 2 (S1M1,S1M0) S1M1 0 0 1 1 (INS0) INSO 0 1 SUM1 MUX ANA IN AMP Source AGC AMP AUX IN AMP S1M0 0 1 0 1 SOURCE BOTH SUM1 MUX ONLY INP ONLY Power Down ARRAY FILTO S1S1 0 0 1 1 2 (S1S1,S1S0) ISD 15 14 13 AIG1 AIG0 AIPD 15 14 13 VLS1 VLS0 VOL2 12 11 10 AXG1 AXG0 AXPD 12 11 VOL1 VOL0 10 S1S1 9 INS0 9 8 7 6 5 AOS2 AOS1 AOS0 AOPD 8 7 6 5 S1S0 S1M1 S1M0 S2M1 S2M0 4 3 OPS1 OPS0 S1S0 0 1 0 1 2 SOURCE ANA IN AMP ARRAY FILTO N/C 1 0 OPA1 OPA0 VLPD 4 3 2 1 0 FLS0 FLD1 FLD0 FLPD AGPD CFG0 CFG1 9 ISD5008 Product Figure 8: ISD5008 Core (Right Half) FILTO FILTER MUX SUM2 SUMMING AMP SUM1 LOW PASS FILTER ARRAY FLS0 0 1 Source SUM1 ARRAY FLPD 0 1 Power Up Power Down 1 1 (FLS0) (FLPD) SUM2 2 (S2M1,S2M0) S2M1 0 0 1 1 S2M0 0 1 0 1 SOURCE BOTH ANA IN ONLY FILTO ONLY Power Down ANA IN AMP XCLK FLD1 0 0 1 1 FLD0 0 1 0 1 SAMPLE RATE 8 kHz 6.4 kHz 5.3 kHz 4 kHz MULTILEVEL STORAGE ARRAY INTERNAL CLOCK 2 (FLD1,FLD0) FILTER PASS BAND 3.4 kHz 2.7 kHz 2.3 kHz 1.7 kHz ARRAY 10 15 14 13 VLS1 VLS0 VOL2 12 11 10 9 VOL1 VOL0 S1S1 S1S0 8 7 6 5 S1M1 S1M0 S2M1 S2M0 4 3 2 FLS0 FLD1 FLD0 1 0 FLPD AGPD CFG1 Voice Solutions in SiliconTM ISD5008 Product Figure 9: Volume Control VOL MUX ANA IN AMP SUM2 SUM1 VOLUME CONTROL VOL INP 3 1 (VLPD) (VOL2,VOL1,VOL0) 2 (VLS1,VLS0) VLS1 0 0 1 1 ISD VLS0 0 1 0 1 SOURCE ANA IN AMP SUM2 SUM1 INP 12 VOL2 0 0 0 0 1 1 1 1 15 14 13 AIG1 AIG0 AIPD 11 15 14 13 VLS1 VLS0 VOL2 VOL1 VOL0 10 AXG1 AXG0 AXPD 12 11 9 INS0 10 9 S1S1 S1S0 8 VOL1 0 0 1 1 0 0 1 1 VOL0 0 1 0 1 0 1 0 1 7 6 VLPD 0 1 Attenuation 0 dB 4 dB 8 dB 12 dB 16 dB 20 dB 24 dB 28 dB 5 AOS2 AOS1 AOS0 AOPD 8 7 6 Power Up Power Down 5 S1M1 S1M0 S2M1 S2M0 4 3 OPS1 OPS0 2 1 0 OPA1 OPA0 VLPD 4 3 2 1 0 FLS0 FLD1 FLD0 FLPD AGPD CFG0 CFG1 11 ISD5008 Product Figure 10: Speaker and AUX OUT Car Kit AUX OUT (1 Vp-p Max) OUTPUT MUX VOL ANA IN AMP Speaker SP+ FILTO SP- 2 (OPA1, OPA0) SUM2 2 (OPS1,OPS0) OPS1 0 0 1 1 15 14 13 12 AIG1 AIG0 AIPD AXG1 AXG0 11 10 AXPD OPS0 0 1 0 1 9 SOURCE VOL ANA IN FILTO SUM2 8 INS0 OPA1 0 0 1 1 7 6 5 4 AOS2 AOS1 AOS0 AOPD OPA0 0 1 0 1 3 SPKR Drive Power Down 3.6 Vp-p @ 150 23 mWatt @ 8 Power Down 2 1 AUX OP Power Down Power Down Power Down 1 Vp-p Max @ 5k 0 OPS1 OPS0 OPA1 OPA0 VLPD CFG0 Figure 11: ANA OUT Output ANA OUT MUX *FTHRU (1 Vp-p max. from AUX IN or ARRAY) (600 mVp-p max. from microphone input) *INP *VOL ANA OUT+ Chip Set *FILTO ANA OUT- *SUM1 1 (AOPD) *SUM2 AOPD 0 1 3 (AOS2,AOS1,AOS0) *DIFFERENTIAL PATH 12 15 14 13 12 AIG1 AIG0 AIPD AXG1 AXG0 11 10 AXPD 9 INS0 8 AOS2 0 0 0 0 1 1 1 1 AOS1 0 0 1 1 0 0 1 1 7 6 AOS0 0 1 0 1 0 1 0 1 5 Power Up Power Down FTHRU INP VOL FILTO SUM1 SUM2 N/C N/C 4 3 AOS2 AOS1 AOS0 AOPD OPS1 OPS0 2 1 0 OPA1 OPA0 VLPD CFG0 Voice Solutions in SiliconTM ISD5008 Product 4 SERIAL PERIPHERAL INTERFACE (SPI) DESCRIPTION The ISD5008 product operates from an SPI serial interface. The SPI interface operates with the following protocol. The data transfer protocol assumes that the microcontroller's SPI shift registers are clocked on the falling edge of the SCLK. With the ISD5008, data is clocked in on the MOSI pin on the rising clock edge. Data is clocked out on the MISO pin on the falling clock edge. 1. All serial data transfers begin with the falling edge of SS pin. 2. SS is held LOW during all serial communications and held HIGH between instructions. 3. Data is clocked in on the rising clock edge and data is clocked out on the falling clock edge. 4. Play and Record operations are initiated by enabling the device by asserting the SS pin LOW, shifting in an opcode and an address field to the ISD5008 device (refer to the Opcode Summary on the page 14). 5. The opcodes and address fields are as follows: <8 control bits> and <16 address bits>. 7. As Interrupt data is shifted out of the ISD5008 MISO pin, control and address data is simultaneously being shifted into the MOSI pin. Care should be taken such that the data shifted in is compatible with current system operation. It is possible to read interrupt data and start a new operation within the same SPI cycle. 8. A record or playback operation begins with the RUN bit set and the operation ends with the RUN bit reset. 9. All operations begin with the rising edge of SS. 4.1 MESSAGE CUEING Message cueing allows the user to skip through messages, without knowing the actual physical location of the message. This operation is used during playback. In this mode, the messages are skipped 1600 times faster than in normal playback mode. It will stop when an EOM marker is reached. Then, the internal address counter will point to the next message. 6. Each operation that ends in an EOM or Overflow will generate an interrupt, including the Message Cueing cycles. The Interrupt will be cleared the next time an SPI cycle is completed.

X = Don't Care. 2. Changes in CFG0 are not recognized until CFG1 is loaded. The changes will occur at the rising edge of SS during the cycle that CFG1 is loaded. 4.2 POWER-UP SEQUENCE The ISD5008 will be ready for an operation after TPUD (25 ms approximately for 8 kHz sample rate). The user needs to wait TPUD before issuing an operational command. For example, to play from address 00 the following programing cycle should be used. The device will start playback at address 00 and it will generate an interrupt when an EOM is reached. It will then stop playback. Record Mode 1. Send POWERUP command. 2. Wait TPUD (power-up delay). Playback Mode 3. Load CFG0 and CFG1 for desired operation. 1. Send POWERUP command. 4. Send SETREC command with address 00. 2. Wait TPUD (power-up delay). 3. Load CFG0 and CFG1 for desired operation. 4.

Important: All changes to the internal settings of the ISD5008 are synchronized with the load of Configuration Register 1. A command to load Configuration Register 1 immediately transfers the input data to the internal settings of the device and the changes take place immediately at the end of the command when SS\ goes HIGH. A load to Configuration Register 0 sends the new data to a temporary register in the ISD5008 and does not affect the internal settings of the device. The next time Configuration Register 1 is loaded, data will also transfer from the temporary register to the Configuration 0 Register and effect the desired changes. See Figure Table 13. 2. Configuration Registers may be loaded with data at any time, including when the chip is powered down using the PU bit in the SPI Control Register. The PU bit in the SPI Control Word will have to be set to a "1" before the changes in configuration will be seen. 18 Voice Solutions in SiliconTM ISD5008 Product Figure 13: Configuration Register Programming Sequence Configuration Register 0 Configuration Register 1 Temporary Register Command = Load Configuration Register 0 } { Command = Load Configuration Register 1 MOSI Input Shift Register (16 bits) Control Word (C7-C0) Figure 14: SPI Interface Simplified Block Diagram Configuration Registers (1) D15 CFG1 D0 D15 CFG0 D0 D15 - D0 1.

It's flexibility allows the user to configure the chip such that almost any input can mixed with any other input and then be directed to any output. The variable settings for the ANA and AUX input amplifiers plus the microphone AGC and speaker volume controls make it possible to use the device with most existing cell phone or cordless phone chip sets with no external level adjustment. Several modes will be found in most applications, however. Please refer to the ISD5008 block diagram to better understand the following modes. In all cases, we are assuming that the chip has been powered up with the PU bit in the SPI control register and that a time period of TPUD has elapsed after that bit was set: FEED THROUGH MODE This mode enables the ISD5008 to connect to a base band cell phone or cordless phone chip set without affecting the audio source or destination. There are two paths involved, the transmit path and the receive path. The transmit path connects the ISD chip's microphone source through to the microphone input on the base band chip set. The receive path connects the base band chip set's speaker output through to the speaker driver on the ISD chip. This allows the ISD chip to substitute for those functions and incidentally gain access to the audio to and from the base band chip set. Figure 15 shows one possible connection to such a chip set. Figure 16 shows the part of the ISD5008 block diagram that is used in Feed Through Mode. The rest of the chip will be powered down to conserve power. The bold lines highlight the audio paths. Note that the Microphone to ANA OUT +/- path is differential. Figure 16: Basic Feed-Thru Mode FTHRU 6 dB INP ANA OUT MUX Chip Set VOL Microphone ANA OUT+ FILTO MIC+ ANA OUT- SUM1 MIC- 1 (AOPD) SUM2 3 (AOS2,AOS1,AOS0) ANA IN .625 /.883 / 1.25 / 1.767 Chip Set VOL ANA IN AMP OUTPUT MUX Speaker ANA IN AMP SP+ FILTO SP- 1 (AIPD) SUM2 2 (OPA1, OPA0) 2 (AIG1,AIG0) 2 (OPS1,OPS0) ISD 21 ISD5008 Product To select this mode, the following control bits must be configured in the ISD5008 configuration registers. To set up the transmit path: 1. Select the FTHRU path through the ANA OUT MUX--Bits AOS0, AOS1 and AOS2 control the state of the ANAOUT MUX. These are the D6, D7 and D8 bits respectively of Configuration Register 0 (CFG0) and they should all be ZERO to select the FTHRU path. 2. Power up the ANA OUT amplifier--Bit AOPD controls the power up state of ANA OUT. This is bit D5 of CFG0 and it should be a ZERO to power up the amplifier. To set up the receive path: 1. Set up the ANA IN amplifier for the correct gain--Bits AIG0 and AIG1 control the gain settings of this amplifier. These are bits D14 and D15 respectively of CFG0. The input level at this pin determines the setting of this gain stage. Table 4 will help determine this setting. In this example we will assume that the peak signal never goes above 1 volt p-p single ended. That would enable us to use the 9dB attenuation setting, or where D14 is ONE and D15 is ZERO. 2. Power up the ANA IN amplifier--Bit AIPD controls the power up state of ANA IN. This is bit D13 of CFG0 and should be a ZERO to power up the amplifier. 3. Select the ANA IN path through the OUTPUT MUX--Bits OPS0 and OPS1 control the state of the OUTPUT MUX. These are bits D3 and D4 respectively of CFG0 and they should be set to the state where D3 is ONE and D4 is ZERO to select the ANA IN path. 4. Power up the Speaker Amplifier--Bits OPA0 and OPA1 control the state of the Speaker and AUX amplifiers. These are bits D1 and D2 respectively of CFG0. They should be set to the state where D1 is ONE and D2 is ZERO. This powers up the Speaker Amplifier and configures it for it's higher gain setting for use with a piezo speaker element and also powers down the AUX output stage. 22 The status of the rest of the functions in the ISD5008 chip must be defined before the configuration registers settings are updated: 1. Power down the Volume Control Element--Bit VLPD controls the power up state of the Volume Control. This is bit D0 of CFG0 and it should be set to a ONE to power down this stage. 2. Power down the AUX IN amplifier--Bit AXPD controls the power up state of the AUX IN input amplifier. This is bit D10 of CFG0 and it should be set to a ONE to power down this stage. 3. Power down the SUM1 and SUM2 Mixer amplifiers--Bits S1M0 and S1M1 control the SUM1 mixer and bits S2M0 and S2M1 control the SUM2 mixer. These are bits D7 and D8 in CFG1 and bits D5 and D6 in CFG1 respectively. All 4 bits should be set to a ONE to power down these two amplifiers. 4. Power down the FILTER stage--Bit FLPD controls the power up state of the FILTER stage in the device. This is bit D1 in CFG1 and should be set to a ONE to power down the stage. 5. Power down the AGC amplifier--Bit AGPD controls the power up state of the AGC amplifier. This is bit D0 in CFG1 and should be set to a ONE to power down this stage. 6. Don't Care bits--The following stages are not used in Feed Through Mode. Their bits may be set to either level. In this example we will set all the following bits to a ZERO. (a). Bit INS0, bit D9 of CFG0 controls the Input Source Mux. (b). Bits AXG0 and AXG1 are bits D11 and D12 respectively in CFG0. They control the AUX IN amplifier gain setting. (c). Bits FLD0 and FLD1 are bits D2 and D3 respectively in CFG1. They control the sample rate and filter band pass setting. (d). Bit FLS0 is bit D4 in CFG1. It controls the FILTER MUX. (e). Bits S1S0 and S1S1 are bits Voice Solutions in SiliconTM ISD5008 Product D9 and D10 of CFG1. They control the SUM1 MUX. (f). Bits VOL0, VOL1 and VOL2 are bits D11, D12 and D13 of CFG1. They control the setting of the Volume Control. (g). Bits VLS0 and VLS1 are bits D14 and D15 of CFG1. They control the Volume Control MUX. The end result of the above set up is amplifier. These are bits D7 and D8 respectively of CFG1 and they should be set to the state where D7 is ONE and D8 is ZERO to select the SUM1 MUX (only) path. 3. Select the SUM1 SUMMING amplifier path through the FILTER MUX--Bit FLS0 controls the state of the FILTER MUX. This is bit D4 of CFG1 and it must be set to ZERO to select the SUM1 SUMMING amplifier path. CFG0=0100 0100 0000 1011 (hex 440B) and CFG1=0000 0001 1110 0011 (hex 01E3). Since both registers are being loaded, CFG0 is loaded followed by the loading of CFG1. These two registers must be loaded in this order. The internal set up for both registers will take effect synchronously with the rising edge of SS. 5.2 CALL RECORD The call record mode adds the ability to record the incoming phone call. In most applications, the ISD5008 would first be set up for Feed Through Mode as described above. When the user wishes to record the incoming call, the set up of the chip is modified to add that ability. For the purpose of this explanation, we will use the 6.4 kHz sample rate during recording. The block diagram of the ISD5008 shows that the Multilevel Storage array is always driven from the SUM2 SUMMING amplifier. The path traces back from there through the LOW PASS Filter, THE FILTER MUX, THE SUM1 SUMMING amplifier, the SUM1 MUX, then from the ANA in amplifier. Feed Through Mode has already powered up the ANA IN amp so we only need to power up and enable the path to the Multilevel Storage array from that point: 1. Select the ANA IN path through the SUM1 MUX--Bits S1S0 and S1S1 control the state of the SUM1 MUX. These are bits D9 and D10 respectively of CFG1 and they should be set to the state where both D9 and D10 are ZERO to select the ANA IN path. 4. Power up the LOWPASS FILTER--Bit FLPD controls the power up state of the LOWPASS FILTER stage. This is bit D1 of CFG1 and it must be set to ZERO to power up the LOW PASS FILTER STAGE. 5. Select the 6.4 kHz sample rate--Bits FLD0 and FLD1 select the Low Pass filter setting and sample rate to be used during record and playback. These are bits D2 and D3 of CFG1. To enable the 6.4 kHz sample rate, D2 must be set to ONE and D3 set to ZERO. 6. Select the LOW PASS FILTER input (only) to the S2 SUMMING amplifier--Bits S2M0 and S2M1 control the state of the SUM2 SUMMING amplifier. These are bits D5 and D6 respectively of CFG1 and they should be set to the state where D5 is ZERO and D6 is ONE to select the LOW PASS FILTER (only) path. In this mode, the elements of the original PASS THROUGH mode do not change. The sections of the chip not required to add the record path remain powered down. In fact, CFG0 does not change and remains CFG0=0100 0100 0000 1011 (hex 440B). CFG1 changes to CFG1=0000 0000 1100 0101 (hex 00C5). Since CFG0 is not changed, it is only necessary to load CFG1. Note that if only CFG0 was changed, it would be necessary to load both registers. 2. Select the SUM1 MUX input (only) to the S1 SUMMING amplifier--Bits S1M0 and S1M1 control the state of the SUM1 SUMMING ISD 23 ISD5008 Product 5.3 MEMO RECORD The Memo Record mode sets the chip up to record from the local microphone into the chip's Multilevel Storage Array. A connected cellular telephone or cordless phone chip set may remain powered down and is not active in this mode. The path to be used is microphone input to AGC amplifier, then through the INPUT SOURCE MUX to the SUM1 SUMMING amplifier. From there the path goes through the FILTER MUX, the LOW PASS FILTER, the SUM2 SUMMING amplifier, then to the MULTILEVEL STORAGE ARRAY. In this instance, we will select the 5.3 kHz sample rate. The rest of the chip may be powered down. 1. Power up the AGC amplifier--Bit AGPD controls the power up state of the AGC amplifier. This is bit D0 of CFG1 and must be set to ZERO to power up this stage. 2. Select the AGC amplifier through the INPUT SOURCE MUX--Bit INS0 controls the state of the INPUT SOURCE MUX. This is bit D9 of CFG0 and must be set to a ZERO to select the AGC amplifier. 3. Select the INPUT SOURCE MUX (only) to the S1 SUMMING amplifier--Bits S1M0 and S1M1 control the state of the SUM1 SUMMING amplifier. These are bits D7 and D8 respectively of CFG1 and they should be set to the state where D7 is ZERO and D8 is ONE to select the INPUT SOURCE MUX (only) path. 4. Select the SUM1 SUMMING amplifier path through the FILTER MUX--Bit FLS0 controls the state of the FILTER MUX. This is bit D4 of CFG1 and it must be set to ZERO to select the SUM1 SUMMING amplifier path. and playback. These are bits D2 and D3 of CFG1. To enable the 5.3 kHz sample rate, D2 must be set to ZERO and D3 set to ONE. 7. Select the LOW PASS FILTER input (only) to the S2 SUMMING amplifier--Bits S2M0 and S2M1 control the state of the SUM2 SUMMING amplifier. These are bits D5 and D6 respectively of CFG1 and they should be set to the state where D5 is ZERO and D6 is ONE to select the LOW PASS FILTER (only) path. To set up the chip for Memo Record, the configuration registers are set up as follows: CFG0=0010 0100 0010 0001 (hex 2421). CFG1=0000 0001 0100 1000 (hex 0148). Only those portions necessary for this mode are powered up. 5.4 MEMO AND CALL PLAYBACK This mode sets the chip up for local playback of messages recorded earlier. The playback path is from the MULTILEVEL STORAGE ARRAY to the FILTER MUX, then to the LOW PASS FILTER stage. From there the audio path goes through the SUM2 SUMMING amplifier to the VOLUME MUX, through the VOLUME CONTROL then to the SPEAKER output stage. We will assume that we are driving a pizeo speaker element. This audio was previously recorded at 8 kHz. All unnecessary stages will be powered down. 1. Select the MULTILEVEL STORAGE ARRAY path through the FILTER MUX--Bit FLS0, the state of the FILTER MUX. This is bit D4 of CFG1 and must be set to ONE to select the MULTILEVEL STORAGE ARRAY. 5. Power up the LOWPASS FILTER--Bit FLPD controls the power up state of the LOWPASS FILTER stage. This is bit D1 of CFG1 and it must be set to ZERO to power up the LOW PASS FILTER STAGE. 2. Power up the LOWPASS FILTER--Bit FLPD controls the power up state of the LOWPASS FILTER stage. This is bit D1 of CFG1 and it must be set to ZERO to power up the LOW PASS FILTER STAGE. 6. Select the 5.3 kHz sample rate--Bits FLD0 and FLD1 select the Low Pass filter setting and sample rate to be used during record 3. Select the 8.0 kHz sample rate--Bits FLD0 and FLD1 select the Low Pass filter setting and sample rate to be used during record 24 Voice Solutions in SiliconTM ISD5008 Product and playback. These are bits D2 and D3 of CFG1. To enable the 8.0 kHz sample rate, D2 and D3 must be set to ZERO. 4. Select the LOW PASS FILTER input (only) to the S2 SUMMING amplifier --Bits S2M0 and S2M1 control the state of the SUM2 SUMMING amplifier. These are bits D5 and D6 respectively of CFG1 and they should be set to the state where D5 is ZERO and D6 is ONE to select the LOW PASS FILTER (only) path. 5. Select the SUM2 SUMMING amplifier path through the VOLUME MUX--Bits VLS0 and VLS1 control the state VOLUME MUX. These bits are bits D14 and D15, respectively of CFG1. They should be set to the state where D14 is ONE and D15 is ZERO to select the SUM2 SUMMING amplifier. (SP+ and SP-) and AUX OUT outputs. These are bits D1 and D2 of CFG0. They must be set to the state where D1 is ONE and D2 is ZERO to power-up the speaker outputs in the HIGH GAIN mode and to power-down the AUX OUT. To set up the chip for Memo or Call Playback, the configuration registers are set up as follows: CFG0=0010 0100 0010 0010 (hex 2422). CFG1=0101 1001 1101 0001 (hex 59D1). Only those portions necessary for this mode are powered up. 6. Power up the VOLUME CONTROL LEVEL-- Bit VLPD controls the power-up state of the VOLUME CONTROL attenuator. This is Bit D0 of CFG0. This bit must be set to a ZERO to power-up the VOLUME CONTROL. 7. Select a VOLUME CONTROL LEVEL--Bits VOL0, VOL1, and VOL2 control the state of the VOLUME CONTROL LEVEL. These are bits D11, D12, and D13, respectively, of CFG1. A binary count of 000 through 111 controls the amount of attenuation through that state. In most cases, the software will select an attenuation level according to the desires of the current users of the product. In this example, we will assume the user wants an attenuation of -12 dB. For that setting, D11 should be set to ONE, D12 should be set to ONE, and D13 should be set to a ZERO. 8. Select the VOLUME CONTROL path through the OUTPUT MUX--These are bits D3 and D4, respectively, of CFG0. They should be set to the state where D3 is ZERO and D4 is a ZERO to select the VOLUME CONTROL. 9. Power up the SPEAKER amplifier and select the HIGH GAIN mode--Bits OPA0 and OPA1 control the state of the speaker ISD 25 ISD5008 Product Table 10: Absolute Maximum Ratings (Packaged Parts)(1) Condition Value Junction temperature 150C Storage temperature range -65C to +150C Voltage applied to any pin (V SS - 0.3 V) to (VCC + 0.3 V) Voltage applied to MOSI, SCLK, INT, RAC and SS pins (Input current limited to 20mA) (V SS - 1.0 V) to 5.5V Lead temperature (soldering - 10 seconds) 300C V CC - VSS -0.3 V to +7.0 V 1.

Typical values: TA = 25C and Vcc = 3.0V. 2. All min/max limits are guaranteed by ISD via electrical testing or characterization. Not all specifications are 100 percent tested. 3. Low-frequency cut off depends upon the value of external capacitors (see Pin Descriptions). 4. Differential input mode. Nominal differential input is 208 mVp-p. (0 dBm0) 5. Sampling frequency can vary as much as -6/+4 percent over the industrial temperature and voltage ranges. For greater stability, an external clock can be utilized (see Pin Descriptions). Sampling frequency will be accurate within 1% for 5.3kHz, and 5% for 4.0, 6.4 and 8.0 kHz sampling rates at room temperature. 6. Playback and Record Duration can vary as much as -6/+4 percent over the industrial temperature and voltage ranges. For greater stability, an external clock can be utilized (See Pin Descriptions). Playback and record durations are accurate within 1% for 5.3kHz, and 5% for 4.0, 6.4 and 8.0kHz sampling rates at room temperature. 7. Filter specification applies to the low pass filter. Therefore, from input to output, expect a 6 dB drop by nature of passing through the filter twice. 8. For optimal signal quality, this maximum limit is recommended. 9. When a record command is sent, TRAC = TRAC + TRACLO on the first row addressed. 10. The maximum signal level at any input is defined as 3.17dB higher than the reference transmission level point. (0TLP) This is the point where signal clipping may begin. 11. Measured at 0TLP point for each gain setting. See Table 4 and Table 5. 12. 0TLP is the reference test level through inputs and outputs. See Table 4 and Table 5. 13. Referenced to 0TLP input at 1kHz, measured over 300 to 3,400 Hz bandwidth. 14. For die, only typical values from Analog Parameters are applicable. 32 Voice Solutions in SiliconTM ISD5008 Product Table 17: SPI AC Parameters(1) Symbol Characteristics Min Max Units TSSS SS Setup Time 500 nsec TSSH SS Hold Time 500 nsec TDIS Data in Setup Time 200 nsec TDIH Data in Hold Time 200 nsec TPD Output Delay 500 nsec TDF Output Delay to hiZ 500 nsec TSSmin SS HIGH TSCKhi 1 sec SCLK High Time 400 nsec TSCKlow SCLK Low Time 400 nsec F0 CLK Frequency 1,000 (2) kHz 1.
