F2MC-16LX MB90495G Series
MB90497G/F497G/F498G/V495G
■DESCRIPTION
The MB90495G Series is a general-purpose, high-performance 16-bit microcontroller. It was designed for devices
like consumer electronics, which require high-speed, real-time process control. This series features an on-chip
full-CAN interface.
In addition to being backwards compatible with the F2MC* family architecture, the instruction set has been ex-
panded to add support for high-lev el language instructions, expanded addressing mode, and enhanced m ultiply/
divide and bit processing instructions. A 32-bit accumulator is also provided, making it possible to process long
word (32-bit) data.
The MB90495G Series peripheral resources include on chip 8/10-bit A/D converter, UART (SCI) 0/1, 8/16-bit
PPG timer, 16-bit I/O timer (16-bit free-run timer, input capture 0, 1, 2, 3 (ICU) ) , and CAN controller.
* : F2MC is the abbreviation of FUJITSU Flexible Microcontroller.

■PRODUCT COMPARISON
Memory Size
When evaluating with evaluation chips and other means, take careful note of the different between the evaluation
chip and the chip actually used. Take particular note of the following.
• While the MB90V495G does not feature an on-chip ROM, the dedicated development tool can be used to
achieve operation equivalent to a product with built-in ROM. Therefore, the ROM size is configured by the
development tool.
• On the MB90V495G, the FF4000H to FFFFFFH image is only visible in the 00 bank, and the FE0000H to
FF3FFFH is only visible in the FE and FF banks (configurable on development tool) .
• On the MB90F497G/F498G/497G, the FF4000H to FFFFFFH image is visible in the 00 bank, and the FF0000H
to FF3FFFH is visible only in the FF bank.

■HANDLING DEVICES
• Make sure you do not exceed the maximum rated values (in order to prevent latch-up) .
• CMOS IC chips may suffer latch-up if a voltage higher than VCC or lower than VSS is applied to an input or
output pin with other than mid or high current resistance; or voltage exceeding the rating is applied across VCC
and VSS pins.
• Latch-ups can dramatically increase the power supply current, causing thermal breakdown of the device.
Make sure that you do not exceed the maximum rated v a lue of your device, in order to prevent a latch-up.
• When turning the analog po wer supply on or off, mak e sure that the analog po w er v oltage (AVCC, AVR) and
analog input voltages do not exceed the digital voltage (VCC) .
• Handling Unused Pins
Leaving unused input/output pins open may cause malfunctions and latch-ups, permanently damaging the
de vice. Pre v ent this b y connecting it to a pull-up or pull-do wn resistor of no less than 2 kΩ. Lea v e unused input/
output pins open in output mode, or if in input mode, handle them in the same as input pins.
• Notes on Using External Clock
When using the external clock, drive pin X0 only, and leave pin X1 unconnected. See below for an example of
external clock use.
Example External Clock Use
• Notes on Not Using Subclock
If you do not connect pins X0A and X1A to an oscillator, use pull-down handling on the X0A pin, and leave the
X1A pin open.
• Power Supply Pins
• If your product has m ultiple VCC or VSS pins, pins of the same potential are internally connected in the de vice
in order to av oid abnormal operation, including latch-up. However, you should make sure to connect the pins’
external power and ground lines, in order to lower unneeded emissions, prevent abnormal operation of strobe
signals due to a rise in ground levels, and maintain total output current within rated levels.
• Take care to connect the VCC and VSS pins of MB90495G Series devices to power lines via the lowest possible
impedance.
• It is recommended that you connect a bypass capacitor of approximately 0.1 μF between VCC and VSS pins near
MB90495G Series device pins.
• Crystal Oscillator Circuit
• Noise in the vicinity of X0 and X1 pins could cause abnormal operations in MB90495G Series devices. Mak e
sure to provide b ypass capacitors via the shortest possib le distance from X0 and X1 pins, crystal oscillators
(or ceramic resonators) , and ground lines. In addition, design your printed circuit boards so as to keep X0
and X1 wiring from crossing other wiring, if at all possible.
• It is strongly recommended that you pro vide printed circuit board artwork surrounding X0 and X1 pins within
a grand area, as this should stabilize operation.

• A/D Converter Power-up and Analog Input Initiation Sequence
• Make sure to power up the A/D converter and analog input (pins AN0 to AN7) after turning on digital pow er
(VCC) .
• Turn off digital power after turning off the A/D conv erter pow er supply and analog inputs. In this case, mak e
sure that the voltage of AVR does not exceed AVCC (it is permissible to turn off analog and digital power
simultaneously) .
• Connecting Unused A/D Converter Pins
If you are not using the A/D converter, set unused pins to AVCC = AVR = VCC, AVSS = VSS.
• Notes for Powering Up
Ensure that the voltage step-up time (between 0.2 V and 2.7 V) at power-up is no less than 50 μs, in order to
prevent malfunction in the built-in step-down circuit.
• Initialization
The device contains built-in registers which are only initialized by a power-on reset. Cycle the power supply to
initialize these registers.
• Stabilizing the Power Supply
Make sure that the VCC power supply voltage is stable. Even at the rated operating VCC power supply voltage,
large, sudden changes in the voltage could cause malfunctions. As a standard for stable power supply, keep
VCC ripples (peak-to-peak value) at commercial power frequencies (50 Hz / 60 Hz) to no more than 10% of the
power supply voltage, and momentary surges caused by switching the power supply and other events to more
than 0.1 V/ms.
• If Output from Ports 0/1 Becomes Undefined
After pow er is turned on, if the RST pin is set to “H” during step-down circuit stabilization standby (during power-
on reset) , por ts 0 and 1 output will be undefined. If the RST pin is set to “L”, por ts 0 and 1 will go into a high
impedance state. Take careful note of the timing of events outlined in figures 1 and 2.

• Caution on Operations during PLL Clock Mode
If the PLL clock mode is selected in the microcontroller, it may attempt to contin ue the operation using the free-
running frequency of the automatic oscillating circuit in the PLL circuitry even if the oscillator is out of place or
the clock input is stopped. Performance of this operation, however, cannot be guaranteed.
• Support for TA = + 125 °C
If used exceeding TA = +105 °C, be sure to contact us for reliability limitations.

■MEMORY MAP
The memor y access modes of the MB90495G Ser ies can be set to single chip mode, internal ROM - external
bus mode, and external ROM - external bus mode.
1. Memory Allocation of the MB90495G
The MB90495G Series has 24-bit inter nal address bus and 24-bit external address bus output, enabling it to
access up to 16 Mbytes of external access memory . The enable/disable time of the ROM mirror function is shown
graphically in the memory map.
2. Memory Map
Note : When the internal R OM is operational, the R OM data in the upper address of bank 00 of the F2MC-16LX is
visible in an image. This is called the ROM mirror function, and takes advantage of the small C compiler model.
With the F2MC-16LX, the lower 16-bit address of bank FF and the lower 16-bit address of bank 00 are set
identical to one another . This allows the ROM-internal table to be ref erenced without specifying a far pointer .
F or e xample, sa y the address “00C000H” is accessed. In actuality, the “FFC000H ” address inside ROM will
be accessed. However, as the ROM space in bank FF exceeds 48 Kbytes, the entire space cannot be viewed
on bank 00’s image. And so, since “FF4000H” to “FFFFFFH” ROM data will be visible on the “004000H” to
“00FFFFH” image, save the ROM data table in the “FF4000H” to “FFFFFFH” space.

2. Time-base Timer
The time-base timer is an 18-bit free-run counter (time-base counter) for counting up in synchronization with the
main clock (1/2 main oscillation clock) .
• Four interval times are available, and interrupt requests can be generated for each interval time.
• The time-base timer also has a function for supplying timers for oscillation stabilize standby time and operating
clocks for peripheral devices.
• Interval timer feature
• When the time-base timer counter reaches the inter val set by the inter val time selection bits (TBTC : TBC1,
TBC0) , it generates an overflow (TBTC : TBOF = 1) and interrupt request.
• If the interrupts due to overflow generation are enabled (TBTC : TBIE = 1) , when an overflow is generated
(TBTC : TBOF = 1) , an interrupt is generated.
• Select from the following 4 time-base timer intervals :
Time-base timer interval times

3. Watchdog Timer
The watchdog timer is a 2-bit timer used as a count clock for the timer-based or watch timer.
If the counter is not cleared within the interval time, it resets the CPU.
• Watchdog Timer Function
• The watchdog timer is a timer counter used to deal with runaway programs. Once the watchdog timer is
launched, it is necessary to keep clearing its counter within the specified interval. If the specified interval
passes without the watchdog timer counter being cleared, the CPU will be reset. This feature is called the
watchdog timer.
• The watchdog timer interval traces back to the clock interval input as the count clock. A watchdog reset is
generated for the smallest to largest times.
• The clock source output destination is set by the watchdog clock selection bit of the watch timer control register
(WTC : WDCS) .
• The watchdog timer interval is set time-base timer output selection bit/watch timer ou tput selection bit of the
watchdog timer control register (WDTC : WT1, WT0) .
Watchdog Timer Intervals
HCLK : oscillation clock (4 MHz) ; SCLK : Subclock (8.192 kHz)
Notes: • If the count clock of the watchdog timer is set to time-base timer output (overflow signal) , then clearing the
time-base timer could make it take longer to reset the watchdog.
• If you are using a subclock as the machine clock, make sure to select watch timer output by setting the
watchdog timer clock source selection bit (WDCS) of the watch timer control register (WTC) to 0.

4. 16-bit I/O Timer
The 16-bit I/O timer is a complex module compr ising one 16-bit free-run timer, and two input capture units (4
input pins) . Clock interval input signals and pulse widths can be measured based on the 16-bit free-run timer.
• 16-bit I/O Timer Configuration
The 16-bit I/O timer is made up of the following modules :
• One 16-bit free-run timer
• Two input capture units (each unit having 2 input pins)
• 16-bit I/O Timer Function
(1) 16-bit free-run timer function
The 16-bit free-run timer consists of a 16-bit up counter, a time counter control status register, and prescaler.
The 16-bit up counter counts up in synchronization with a fraction of the machine clock.
• The count clock can be set to one of eight fractions of the machine clock. The external clock signals input to
the 16-bit free-run timer clock input pin (FRCK) can be used as the count clock.
• Interrupts can be generated in response to counter value overflows.
• Interrupts launch the extended intelligent I/O service (EI2OS) .
• The count value of the 16-bit free-r un timer can be cleared to “0000 H” by either a reset, or software clear via
the timer count clear bit (TCCS : CLR) .
• The count value of the 16-bit free-run timer is output to the input capture, and used as the base time for capture
operation.
(2) Input Capture Function
When the input capture detects that an external signal edge has been input to an input pin, it stores the count
v alue of the 16-bit free-run timer in the input capture data register, f or the point at which the edge was detected.
The input capture consists of an input capture register corresponding to four I/O pins, an input capture control
status register, and an edge detection circuit.
• When an edge is detected, either rising, falling, or both can be selected.
• An interrupt request can be generated to the CPU when an input signal edge is detected.
• Interrupts launch the extended intelligent I/O service (EI2OS) .
• Since the input capture has four pairs of input pins and input capture data registers, it can measure up to 4
phenomena.

Note: The 16-bit I/O timer contains one 16-bit free-r un timer.
The interrupt request number of the 16-bit free-r un timer is as follows :
Interrupt request number : 19 (13H)
Prescaler: Takes a fraction of the machine clock, and supplies a count clock to the 16-bit up-counter. One of
four machine clock fractions can be selected by setting the timer counter control status register
(TCCS) .
Timer Counter Register (TCDT) :
This is a 16-bit up-counter. It is possible to read the current counter value of the 16-bit free-run timer
by reading this counter. The counter can be set to an arbitrary value by writing to it while stopped.
Timer Counter Control Status Register (TCCS) :
TCCS selects the divide ratio of a machine clock, executes software clear of counter values. and
enables or disables counter operation. Also TCCS confirms and clears an overflow generation flag,
and enables or disables interruption.

5. 16-bit Reload Timer
The functions of the 16-bit reload timer are as follows :
• Choose one of three internal clocks or an external event clock as the count clock.
• Choose a software or external launch trigger.
• An interrupt can be sent to the CPU in response to an underflow generated by the 16-bit timer register. Interrupts
can be used to utilize the timer as an interval timer.
• When an underflow is generated by the 16-bit timer register (TMR) , select one-shot mode, where TMR counter
operation is halted, or reload mode, where the 16-bit reload register value is reloaded, and TMR count operation
continues.
• Supports extended intelligent I/O service (EI2OS) .
• The MB90495G Series features two on-chip 16-bit reload timer channels.
•16-bit Reload Timer Operation Mode
• Internal Clock Mode
• Set the count clock selection bits of the timer control status register (TMCSR : CSL1, CSL0) to “00B”, “01B” or
“10B” to set the 16-bit reload timer to internal clock mode.
• In internal clock mode, the timer counts down in synchronization with the internal clock.
• Set the count clock selection bits of the timer control status register (TMCSR : CSL1, CSL0) to select one of
three count clock intervals.
• Select software-triggered or externally triggered (edge detection) launch.

6. Watch Timer
The watch timer is a 15-bit free-run counter that counts up in synchronization with the subclock.
• Eight different intervals can be selected, and interrupt requests generated for each interval time.
• Supplies a timer f or subclock oscillation stabilization standby, and an operational cloc k for the w atchdog timer .
• The subclock is always the count clock, regardless of the clock selection register (CKSCR) setting.
• Interval timer feature
• When the inter val time set by the interval time selection bits (WTC : WTC2 to WTC0) is reached, the clock
timer generates an overflow in the bits corresponding to the interval time of the w atch timer counter, and sets
the overflow flag bit (WTC : WTOF = 1) .
• Interrupts ar ising from overflows are enabled (WTC : WTIE = 1) , an interrupt request is generated when the
overflow flag bit is set (WTC : WTOF = 1) .
• Select from one of the following 8 watch timer intervals :

7. 8/16-Bit PPG
The 8/16-bit PPG timer is a 2-channel reload timer module (PPG0, PPG1) capable of arbitrary synchronization
and pulse output of duty ratio. Combining the 2 channel module can yield the following behavior :
• 8-bit PPG output, 2-channel independent operation mode
• 16-bit PPG output operation mode
• 8 + 8-bit PPG output operation mode
The MB90495G Series features two on-chip, 8/16-bit PPG timers. This section describes the functions of PPG0/
1. PPG2/3 has the same functions as PPG0/1.
• 8/16-bit PPG Timer Functions
The 8/16-bit PPG timer is made up of f our 8-bit reload registers (PRLH0/PRLL0, PRLH1/PRLL1) , and two PPG
down counters (PCNT0, PCNT1) .
• Since you can set each output pulse to “H” or “L” width independently, the interval and duty ratio of each
pulse can be set to an arbitrary value.
• Select one of 6 internal clocks as the count clock.
• Interrupt requests can be generated f or each interval time, allo wing the timer to be used as an interv al timer .
• The use of an external circuit allows the timer to be used as a D/A converter.

9. DTP/External Interrupts
The DTP/external interrupt transmits interrupt requests or data transfer requests generated by peripheral devices
to the CPU, generates external interrupt request, and starts the extended intelligent I/O service (EI2OS) .
• DTP/External Interrupt Functions
Outputs interrupt requests from external peripheral devices to the CPU using the same procedure as f or periph-
eral functions, and generates external interrupts, or starts the extended intelligent I/O service (EI2OS) .
If the interrupt control register is configured to prohibit the extended intelligent I/O service (EI2OS) (ICR : ISE =
0) , then the external interrupt feature becomes valid, and the process branches into interrupt processing.
If the EI2OS is enabled (ICR : ISE = 1) , then the DTP function becomes valid, and the EI2OS automatically
transmits data, and after transmitting data a specified number of times, branches into interrupt processing.
Overview of DTP/External Interrupts
External interrupt DTP functions
Input pins 8 (INT0 to INT7)
Interrupt condition Each pin sets individually in the detection level configuration register (ELVR)

approximation conversion.
• The input signal can be selected from an 8-channel analog input pin set.
• Select a software trigger, internal timer output, or external trigger as the start trigger.
• Functions of the 8/10-bit A/D Converter
Converts analog voltage (input voltage) input to the analog input pins to 8-bit or 10-bit digital values. (A/D
conversion)
The 8/10-bit A/D converter has the fo llowing features :
• Single-channel A/D conversion time is a minimum of 6.12 μs, including sampling time.*
• Single-channel sampling time is a minimum of 2.0 μs.*
• RC-type successive approximation with sampling and hold circuits is used for conversion.
• Select 8 or 10-bit resolution.
• Analog input pins can use up to 8 channels.
• A/D conversion results are stored in the A/D data register, allowing them to be used to generate interrupts.
• Interrupt requests launch the EI2OS. Use the EI2OS to prevent dropped data even with continuous A/D con-
version.
• Select software, internal timer output, or external trigger (falling edge) as the start trigger.
* : With machine clock operating at 16 MHz
•Conversion Modes of the 8/10-bit A/D Converter
Conversion Mode Description
Single conversion mode Conducts A/D conversion for each channel in turn, from the start channel to the end
channel. When A/D conversion of the end channel is completed, the A/D conversion
function halts.
Continuous conversion
mode
Conducts A/D conversion for each channel in turn, from the start channel to the end
channel. When A/D conversion of the end channel is completed, the function returns
to the start channel and continues A/D conversion.
Stop conversion mode Suspends each channel and conducts A/D conversion, one at a time. When A/D
conversion of the end channel is completed, the function returns to the start channel
and repeats the A/D conversion and channel stop.

13. ROM Correction Function
In the case that the address of the instruction after the one that a progr am is currently processing matches the
address configured in the detection address configuration register, the progr am fo rces the next instruction to be
processed into an INT9 instruction, and branches to the interrupt process program. Since processing can be
conducted using INT9 interrupts, programs can be repaired using batch processing.
• Overview of the ROM Correction Function
• The address of the instruction after the one that a program is currently processing is always stored in an
address latch via the internal data bus. ROM correction constantly compares the address stored in the address
latch with the one configured in the detection address configuration register. If the two compared addresses
match, the CPU forcibly changes this instruction into an INT9 instruction, and executes an interrupt processing
program.
• There are two detection address configuration registers : PADR0 and PADR1. Each register provides an
interrupt enable bit. This allows y ou to individually configure each register to enab le/prohibit the generation of
interrupts when the address stored in the address latch matches the one configured in the detection address
configuration register.
• ROM Correction Block Diagram
• Address latch
Stores value of address output to internal data bus.
• Address detection control register (PACSR)
Set this register to enable/prohibit interrupt output when an address match is detected.
• Detection address configuration register (PADR0, PADR1)
Configure an address with which to compare the address latch value.

15. 512-K/1-M bit Flash Memory
• Overview
There are three methods available for writing/deleting data to/from flash memory :
1. Parallel writer
2. Serial dedicated writer
3. Program runtime write/delete
• Overview of 512-K/1-M bit flash memory
512-Kbit flash memory is arra yed in bank FFH on the CPU memory map , 1-Mbit flash memory is array ed in bank
FEH to FFH on the CPU memory map. The flash memory interface circuit provides read and program access
from the CPU.
Since instructions from the CPU are carried out via the flash memory interface circuit, flash memory can be
overwritten at the implementation level. This allows you to efficiently improve programs and data.
• Features of 512-K/1-M bit Flash Memory
• 512-Kbit flash memory : 64 KWords × 8-bit/32 KW ords × 16-bit (16-Kbyte + 8-Kbyte + 8-Kbyte + 32-Kbyte)
sector architecture
• 1-Mbit flash memory : 128 KWords × 8-bit/64 KW ords × 16-bit (16-Kbyte + 8-Kbyte + 8-Kb yte + 32-Kbyte +
64-Kbyte) sector architecture
• Auto program algorithm (Embedded Algorithm : same as MBM29LV200)
• On-chip delete suspend/delete resume functions
• Data polling, write/delete completion detection through toggle bit
• Write/delete completion detection from CPU overwrite
• Sector-specific deletion available (sectors can be combined as desired)
• Write/delete iterations (minimum) : 10,000
Notes : There is no function to read the manufacture or device code.
These codes also cannot be accessed through commands.
• Flash memory write/delete
• It is not possible to simultaneously write to and read from flash memory.
• When writing to or deleting from flash memory, first copy the program residing in flash memory into RAM,
then execute the program copied into RAM. This will allow you to write to flash memory.

means with external components, the ICLAMP rating supersedes the VI rating.
*3 : The rating for the maximum output current is the peak value of one of the corresponding pins.
*4 : The standard for computing average output current is the av erage current output from one of the corresponding
pins over a period of 100 ms (the av er age v a lue is tak en b y multiplying oper ating current by operational rate) .
*5 : The standard for computing average total output current is the average current output from all of the corre-
sponding pins over a period of 100 ms (the average value is taken by multiplying operating current by operational
rate) .
*6 : • Applicable to pins: P00 to P07, P10 to P17, P20 to P27, P30 to P37, P40 to P44, P50 to P57, P60 to P63
• Use within recommended operating conditions.
• Use at DC voltage (current)
• The +B signal should always be applied a limiting resistance placed between the +B signal and the
microcontroller.
• The value of the limiting resistance should be set so that when the +B signal is applied the input current to
the microcontroller pin does not exceed rated values, either instantaneously or for prolonged periods.
• Note that when the microcontroller drive current is low, such as in the power saving modes, the +B input
potential may pass through the protective diode and increase the potential at the VCC pin, and this may affect
other devices. (Continued)

• Note that if a +B signal is input when the microcontroller power supply is off (not fixed at 0 V) , the power
supply is provided from the pins, so that incomplete operation may result.
• Note that if the +B input is applied during power-on, the power supply is provided from the pins and the resulting
supply voltage may not be sufficient to operate the power-on reset.
• Care must be taken not to leave the +B input pin open.
• Note that analog system input/output pins other than the A/D input pins (LCD drive pins, comparator input
pins, etc.) cannot accept +B signal input.
• Sample recommended circuits:

2. Recommended Operating Conditions (VSS = AVSS = 0.0 V)
*1 : Use a ceramic capacitor, or one with approximately the same frequency characteristics. The b ypass capacitor
of the VCC pin should have a greater capacity than CS.
See the figure below for details about connecting a smooth capacitor to the CS.
*2 : If used exceeding TA = +105 °C, be sure to contact us for reliability limitations.
WARNING: The recommended operating conditions are required in order to ensure the normal operation of
the semiconductor device. All of the device's electrical characteristics are warranted when the
device is operated within these ranges.
Always use semiconductor devices within their recommended operating condition ranges.
Operation outside these ranges may adversely affect reliability and could result in device failure.
No warranty is made with respect to uses, operating conditions, or combinations not represented
on the data sheet. Users considering application outside the listed conditions are advised to contact
their representatives beforehand.

It is recommended that you keep the rising
speed to no more than 50 mV/ms.
Sudden changes in the power supply voltage may cause a power-on reset. To change the power
supply voltage while the device is in operation, it is recommended that you raise the voltage at a
steady rate, in order to suppress fluctuations (see figure below). In this case, perform this operation
when the PLL clock is not being used. If, however, the voltage falling speed is no more than 1 V/s,
it is permissible to perform this operation while using the PLL clock.

Resolution : Analog changes that are identifiable with the A/D converter
Linearity error : The deviation of the straight line connecting the zero tr ansition point
( “00 0000 0000” ←→ “00 0000 0001” ) with the full-scale transition point
( “11 1111 1110” ←→ “11 1111 1111” ) from actual conversion characteristics.
Differential linearity error : The deviation of input voltage needed to change the output code by 1 LSB from the
ideal value.
Total error : The difference between the actual v alue and the theoretical v alue, which includes
zero-transition error/full-scale tr ansition error, linearity error, and differential linear-
ity error.

7. Notes on Using A/D Converter
Select the output impedance v alue for the e xternal circuit of analog input according to the follo wing conditions :
External circuit output impedance values of about 5 kΩ or lower are recommended.
If external capacitors are used, a capacitance of several thousand times the internal capacitor value is recom-
mended in order to minimize the effect of vo ltage distrib ution between the external and internal capacitor.
If the output impedance of the external circuit is too high, the sampling time for analog voltages may not be
sufficient (sampling period = 2.00 μs @ machine clock of 16 MHz) .
•About Error
The smaller the absolute value of | AVR - AVSS |, the greater the relative error.

DESCRIPTION
The MB90495G series with FULL-CAN and FLASH ROM is specially designed for
automotive and industrial applications. Its main features is the on board CAN Interface,
which conform to V2.0 Part A and Part B, supporting very flexible message buffering. Thus,
offering more functions than a normal full CAN approach. Fujitsu offers on-chip FLASH-
ROM program memory. An internal voltage booster substitutes the necessity of a second
programming voltage. An on board voltage regulator provides 3V to the internal MCU core.
This constitutes a major advantage in terms of EMI and power consumption. The internal
PLL clock frequency multiplier, provides an internal 62.5 nsec instruction cycle time with an
external 4 MHz clock. Further more it features 4 channels Output Capture Units and 8
channels Input Capture Units with a 16-bit free running timer. Two UARTs constitute
additional functionality for communication purposes. The external bus interface allows full
use to be made of the 16MByte address space. A 32-bit accumulator is also provided,
making it possible to process long word (32-bit) data. The MB90495G Series peripheral
resources include on chip 8/10-bit A/D converter, UART (SCI) 0/1, 8/16-bit PPG timer, 16-
bit I/O timer (16-bit free-run timer, input capture 0, 1, 2, 3 (ICU) ) , and CAN controller.
