Initial devices in this 3.3V family are a 4-megabit, a 2-megabit, a 1-megabit, a 512-Kbit, and a 256-Kbit PROM that provide an easy-to-use, cost-effective method for re-programming and storing large Xilinx FPGA or CPLD configuration bitstreams. When the FPGA is in Master Serial mode, it generates a configuration clock that drives the PROM. A short access time after the rising CCLK, data is available on the PROM DATA (D0) pin that is connected to the FPGA DIN pin. The FPGA generates the appropriate number of clock pulses to complete the configuration. When the FPGA is in Slave Serial mode, the PROM and the FPGA are clocked by an external clock. TMS TDI Control and JTAG Interface TDO Multiple devices can be concatenated by using the CEO output to drive the CE input of the following device. The clock inputs and the DATA outputs of all PROMs in this chain are interconnected. All devices are compatible and can be cascaded with other members of the family or with the XC17V00 one-time programmable Serial PROM family. OE/Reset CLK CE TCK When the FPGA is in Slave-Parallel or SelectMAP Mode, an external oscillator generates the configuration clock that drives the PROM and the FPGA. After the rising CCLK edge, data are available on the PROMs DATA (D0-D7) pins. The data is clocked into the FPGA on the following rising edge of the CCLK. Neither Slave-Parallel nor SelectMAP utilize a Length Count, so a free-running oscillator can be used.

In-system programming offers quick and efficient design iterations and eliminates unnecessary package handling or socketing of devices. The Xilinx development system provides the programming data sequence using either Xilinx JTAG Programmer software and a download cable, a third-party JTAG development system, a JTAG-compatible board tester, or a simple microprocessor interface that emulates the JTAG instruction sequence. The JTAG Programmer software also outputs www.xilinx.com 1-800-255-7778 DS026 (v3.0) November 12, 2001 Product Specification R XC18V00 Series of In-System Programmable Configuration PROMs serial vector format (SVF) files for use with any tools that accept SVF format and with automatic test equipment. All outputs are held in a high-impedance state or held at clamp levels during in-system programming. OE/RESET The ISP programming algorithm requires issuance of a reset that causes OE to go Low. External Programming Xilinx reprogrammable PROMs can also be programmed by the Xilinx HW-130 device programmer. This provides the added flexibility of using pre-programmed devices in board design and boundary-scan manufacturing tools, with an in-system programmable option for future enhancements and design changes. Reliability and Endurance cycles and a minimum data retention of 20 years. Each device meets all functional, performance, and data retention specifications within this endurance limit. Design Security The Xilinx in-system programmable PROM devices incorporate advanced data security features to fully protect the programming data against unauthorized reading. Table 3 shows the security setting available. The read security bit can be set by the user to prevent the internal programming pattern from being read or copied via JTAG. When set, it allows device erase. Erasing the entire device is the only way to reset the read security bit.

A Test Access Port (TAP) and registers are provided to support all required boundary scan instructions, as well as many of the optional instructions specified by IEEE Std. 1149.1. In addition, the JTAG interface is used to implement in-system pro- DS026 (v3.0) November 12, 2001 Product Specification gramming (ISP) to facilitate configuration, erasure, and verification operations on the XC18V00 device.

The IDCODE register is 32 bits wide. The IDCODE register can be shifted out for examination by using the IDCODE instruction. The IDCODE is available to any other system component via JTAG. The IDCODE register has the following binary format: vvvv:ffff:ffff:aaaa:aaaa:cccc:cccc:ccc1 where XC18V00 Specific Instructions 11101110 For each input pin, the register stage controls and observes the input state of the pin.

In preparation for an instruction scan sequence, the instruction register is parallel loaded with a fixed instruction capture pattern. This pattern is shifted out onto TDO (LSB first), while an instruction is shifted into the instruction register from TDI. The detailed composition of the instruction capture pattern is illustrated in Figure 3. c = the company code (49h for Xilinx) Note: The LSB of the IDCODE register is always read as logic "1" as defined by IEEE Std. 1149.1 Table 5 lists the IDCODE register values for the XC18V00 devices.

This simplifies system designs and allows standard Automatic Test Equipment to perform both functions. The AC characteristics of the XC18V00 TAP are described as follows. Figure 4 shows the timing relationships of the TAP signals. These TAP timing characteristics are identical for both boundary-scan and ISP operations.

The Master FPGA CCLK output drives the CLK input(s) of the PROM(s) (in Master Serial mode only). The CEO output of a PROM drives the CE input of the next PROM in a daisy chain (if any). The OE/RESET input of all PROMs is best driven by the INIT output of the lead FPGA device. This connection assures that the PROM address counter is reset before the start of any (re)configuration, even DS026 (v3.0) November 12, 2001 Product Specification when a reconfiguration is initiated by a VCC glitch. * * The PROM CE input can be driven from the DONE pin. The CE input of the first (or only) PROM can be driven by the DONE output of the first FPGA device, provided that DONE is not permanently grounded. CE can also be permanently tied Low, but this keeps the DATA output active and causes an unnecessary supply current of 10 mA maximum. Slave-Parallel/SelectMap mode is similar to slave serial mode. The DATA is clocked out of the PROM one byte per CCLK instead of one bit per CCLK cycle. See FPGA data sheets for special configuration requirements. www.xilinx.com 1-800-255-7778 7 R XC18V00 Series of In-System Programmable Configuration PROMs Initiating FPGA Configuration The XC18V00 devices incorporate a pin named CF that is controllable through the JTAG CONFIG instruction. Executing the CONFIG instruction through JTAG pulses the CF low for 300-500 ns, which resets the FPGA and initiates configuration. The CF pin must be connected to the PROGRAM pin on the FPGA(s) to use this feature. The JTAG Programmer software can also issue a JTAG CONFIG command to initiate FPGA configuration through the "Load FPGA" setting. Selecting Configuration Modes The XC18V00 accommodates serial and parallel methods of configuration. The configuration modes are selectable through a user control register in the XC18V00 device. This control register is accessible through JTAG, and is set using the "Parallel mode" setting on the Xilinx JTAG Programmer software. Serial output is the default programming mode. Master Serial Mode Summary The I/O and logic functions of the Configurable Logic Block (CLB) and their associated interconnections are established by a configuration program. The program is loaded either automatically upon power up, or on command, depending on the state of the three FPGA mode pins. In Master Serial mode, the FPGA automatically loads the configuration program from an external memory. Xilinx PROMs are designed to accommodate the Master Serial mode. Upon power-up or reconfiguration, an FPGA enters the Master Serial mode whenever all three of the FPGA mode-select pins are Low (M0=0, M1=0, M2=0). Data is read from the PROM sequentially on a single data line. Synchronization is provided by the rising edge of the temporary signal CCLK, which is generated by the FPGA during configuration. Master Serial Mode provides a simple configuration interface. Only a serial data line, a clock line, and two control lines are required to configure an FPGA. Data from the PROM is read sequentially, accessed via the internal address and bit counters which are incremented on every valid rising edge of CCLK. If the user-programmable, dual-function DIN pin on the FPGA is used only for configu- 8 ration, it must still be held at a defined level during normal operation. The Xilinx FPGA families take care of this automatically with an on-chip pull-up resistor. Cascading Configuration PROMs For multiple FPGAs configured as a serial daisy-chain, or a single FPGA requiring larger configuration memories in a serial or SelectMAP configuration mode, cascaded PROMs provide additional memory (Figure 5). Multiple XC18V00 devices can be concatenated by using the CEO output to drive the CE input of the downstream device. The clock inputs and the data outputs of all XC18V00 devices in the chain are interconnected. After the last bit from the first PROM is read, the next clock signal to the PROM asserts its CEO output Low and drives its DATA line to a high-impedance state. The second PROM recognizes the Low level on its CE input and enables its DATA output. See Figure 6. After configuration is complete, address counters of all cascaded PROMs are reset if the PROM OE/RESET pin goes Low. www.xilinx.com 1-800-255-7778 DS026 (v3.0) November 12, 2001 Product Specification R XC18V00 Series of In-System Programmable Configuration PROMs Vcc Vcco Vcc Vcco Vcc 4.7K Vcc MODE PINS* Vcc DOUT DIN DIN Vcc D0 Vcco J1 TDI TMS TCK TDO 1 2 3 4 D0 Vcc Xilinx FPGA Vcco XC18V00 XC18V00 Cascaded PROM First PROM Vcc MODE PINS* Xilinx FPGA 4.7K Master Serial Slave Serial ** CLK CCLK CCLK TMS CE TMS CE DONE DONE TCK CEO TCK CEO TDI GND CLK TDI OE/RESET OE/RESET CF CF TDO GND TDO INIT INIT PROGRAM PROGRAM TDI TDI TMS TCK TMS TDO * For Mode pin connections, refer to appropriate FPGA data sheet. ** Virtex, Virtex-E is 300 ohms, all others are 4.7K.

This allows 5V CMOS signals to connect directly to the PROM inputs without damage. In addition, the 3.3V VCC power supply can be applied before or after 5V signals are applied to the I/Os. In mixed 5V/3.3V/2.5V systems, the user pins, the core power supply (VCC), and the output power supply (VCCO) can have power applied in any order. This makes the PROM devices immune to power supply sequencing issues. Reset Activation low until the XC18V00 voltage reaches the operating voltage range. If the power drops below 2.0V, the PROM resets. OE/RESET polarity is NOT programmable. Standby Mode The PROM enters a low-power standby mode whenever CE is asserted High. The output remains in a high-impedance state regardless of the state of the OE input. JTAG pins TMS, TDI and TDO can be in a high-impedance state or High. Customer Control Pins On power up, OE/RESET is held low until the XC18V00 is active (1 ms) and able to supply data after receiving a CCLK pulse from the FPGA. OE/RESET is connected to an external resistor to pull OE/RESET HIGH releasing the FPGA INIT and allowing configuration to begin. OE/RESET is held The XC18V00 PROMs have various control bits accessible by the customer. These can be set after the array has been programmed using "Skip User Array" in Xilinx JTAG Programmer Software.
