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 expanded to add support for high-level language instructions, expanded addressing mode, and enhanced multiply/
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 value of your device, in order to prevent a latch-up.
• When turning the analog power supply on or off, make sure that the analog power voltage (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
device. Prevent this by connecting it to a pull-up or pull-down resistor of no less than 2 kΩ. Leave 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.

X1
MB90495G Series
• 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 multiple VCC or VSS pins, pins of the same potential are internally connected in the device
in order to avoid 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. Make
sure to provide bypass capacitors via the shortest possible 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 provide 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 power
(VCC) .
• Turn off digital power after turning off the A/D converter power supply and analog inputs. In this case, make
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 power is turned on, if the RST pin is set to “H” during step-down circuit stabilization standby (during poweron reset) , ports 0 and 1 output will be undefined. If the RST pin is set to “L”, ports 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 continue the operation using the freerunning 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.

* : Addresses #1 and #3 are product-specific.
Note : When the internal ROM is operational, the ROM 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 referenced without specifying a far pointer.
For example, say 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.

■ PERIPHERAL RESOURCES
1. I/O Port
(1) Overview
General-purpose (parallel) I/O ports can be used as the I/O ports. The MB90495G Series has 7 ports (49) .
Each port doubles as a peripheral device I/O pin.
• I/O Port Features
I/O ports output data to I/O pins and load signals input to them, by means of the port data register (PDR) .
Additionally, the port direction register (DDR) sets the I/O direction of the I/O pins at the bit level. Below is a
description of each pin’s function, and the peripheral device that shares it.
• Port 0 : general-purpose I/O port/doubles as external address data bus pin
• Port 1 : general-purpose I/O port/doubles as PPG timer output, input capture input, and external address data
bus pin
• Port 2 : general-purpose I/O port/doubles as reload timer I/O, external interrupt input pin, and external address
bus pin
• Port 3 : general-purpose I/O port/doubles as UART0 I/O, free-run timer, and A/D converter startup trigger pin
• Port 4 : general-purpose I/O port/doubles as UART1 I/O, and CAN controller transmit/receive pin
• Port 5 : general-purpose I/O port/doubles as analog input pin
• Port 6 : general-purpose I/O port/doubles as external interrupt input pin

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 interval set by the interval 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
Count Clock
Interval Time
212/HCLK (approx. 1.0 ms)
214/HCLK (approx. 4.1 ms)

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 output selection bit of the
watchdog timer control register (WDTC : WT1, WT0) .

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.

The 16-bit I/O timer is a complex module comprising 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-run timer can be cleared to “0000H” 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
value of the 16-bit free-run timer in the input capture data register, for 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-run timer.
The interrupt request number of the 16-bit free-run 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.

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 for subclock oscillation stabilization standby, and an operational clock for the watchdog timer.
• The subclock is always the count clock, regardless of the clock selection register (CKSCR) setting.
• Interval timer feature
• When the interval 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 watch timer counter, and sets
the overflow flag bit (WTC : WTOF = 1) .
• Interrupts arising 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 four 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 for each interval time, allowing the timer to be used as an interval timer.
• The use of an external circuit allows the timer to be used as a D/A converter.

13. ROM Correction Function
In the case that the address of the instruction after the one that a program is currently processing matches the
address configured in the detection address configuration register, the program forces 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 you to individually configure each register to enable/prohibit the generation of
interrupts when the address stored in the address latch matches the one configured in the detection address
configuration register.

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 arrayed in bank FFH on the CPU memory map, 1-Mbit flash memory is arrayed 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 KWords × 16-bit (16-Kbyte + 8-Kbyte + 8-Kbyte + 32-Kbyte)
sector architecture
• 1-Mbit flash memory : 128 KWords × 8-bit/64 KWords × 16-bit (16-Kbyte + 8-Kbyte + 8-Kbyte + 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.

*1 : AVCC and AVR shall never exceed VCC. Also, AVR shall never exceed AVCC.
*2 : VI and VO shall never exceed VCC + 0.3 V. However, if the maximum current to/from an input is limited by some
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 average current output from one of the corresponding
pins over a period of 100 ms (the average value is taken by multiplying operating current by operational rate) .
*5 : The standard for computing average total output current is the average current output from all of the corresponding 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.

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.

6. A/D Converter Glossary
Resolution
Linearity error
: Analog changes that are identifiable with the A/D converter
: The deviation of the straight line connecting the zero transition 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 value and the theoretical value, which includes
zero-transition error/full-scale transition error, linearity error, and differential linearity error.

7. Notes on Using A/D Converter
Select the output impedance value for the external circuit of analog input according to the following 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 recommended in order to minimize the effect of voltage distribution 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) .
