■ DESCRIPTION
MB90455 series devices are general-purpose high-performance 16-bit micro controllers designed for process
control of consumer products, which require high-speed real-time processing.
The system, inheriting the architecture of F2MC* family, employs additional instruction ready for high-level languages, expanded addressing mode, enhanced multiply-divide instructions, and enriched bit-processing instructions. Furthermore, employment of 32-bit accumulator achieves processing of long-word data (32 bits).
The peripheral resources of MB90455 series include the following:
8/10-bit A/D converter, UART 1, 8/16-bit PPG timer, 16-bit input-output timer (16-bit free-run timer, input capture
0, 1, 2, 3 (ICU)).
*: F2MC is the abbreviation of FUJITSU Flexible Microcontroller.
■ FEATURES
• Clock
• Built-in PLL clock frequency multiplication circuit
• Selection of machine clocks (PLL clocks) is allowed among frequency division by two on oscillation clock, and
multiplication of 1 to 4 times of oscillation clock (for 4-MHz oscillation clock, 4 MHz to 16 MHz).
• Operation by sub-clock (8.192 kHz) is allowed.
• Minimum execution time of instruction: 62.5 ns (when operating with 4-MHz oscillation clock, and 4-time multiplied PLL clock).

Memory space
When testing with test product for evaluation, check the differences between the product and a product to be
used actually. Pay attention to the following points:
• The MB90V495G has no built-in ROM. However, a special-purpose development tool allows the operations
as those of one with built-in ROM. ROM capacity depends on settings on a development tool.
• On MB90V495G, an image from FF4000H to FFFFFFH is viewed on 00 bank and an image of FE0000H to
FF3FFFH is viewed only on FE bank and FF bank. (Modified on settings of a development tool.)
• On MB90F455 (S) /F456 (S) /F457 (S) , MB90455 (S) /456 (S) /457 (S) , an image from FF4000H to FFFFFFH
is viewed on 00 bank and an image of FE0000H to FF3FFFH is viewed only on FF bank.

■ HANDLING DEVICES
• Do not exceed maximum rating (preventing “latch up”)
• On a CMOS IC, latch-up may occur when applying a voltage higher than Vcc or a voltage lower than Vss to
input or output pin, which has no middle or high withstand voltage. Latch-up may also occur when a voltage
exceeding maximum rating is applied across Vcc and Vss.
• Latch-up causes drastic increase of power current, which may lead to destruction of elements by heat. Extreme
caution must be taken not to exceed maximum rating.
• When turning on and off analog power source, take extra care not to apply an analog power voltages (AVcc
and AVR) and analog input voltage that are higher than digital power voltage (Vcc).
• Handling unused pins
• Leaving unused input pins open may cause permanent destruction by malfunction or latch-up. Apply pull-up
or pull-down process to the unused pins using resistors of 2 kΩ or higher. Leave unused input/output pins
open under output status, or process as input pins if they are under input status.
• Using external clock
• When using an external clock, drive only X0 pin and leave X1 pin open. An example of using an external clock
is shown below.
Using external clock
X0
Open
X1
MB90455 series
• Notes when using no sub clock
• If an oscillator is not connected to X0A and X1A pin, apply pull-down resistor to X0A pin and leave X1A pin open.
• About power supply pins
• If two ore more Vcc and Vss exist, the pins that should be at the same potential are connected to each other
inside the device. For reducing unwanted emissions and preventing malfunction of strobe signals caused by
increase of ground level, however, be sure to connect the Vcc and Vss pins to the power source and the ground
externally.
• Pay attention to connect a power supply to Vcc and Vss of MB90455 series device in a lowest-possible
impedance.
• Near pins of MB90455 series device, connecting a bypass capacitor is recommended at 0.1 μF across Vcc
and Vss.
• Crystal oscillator circuit
• Noises around X0 and X1 pins cause malfunctions on a MB90455 series device. Design a print circuit so that
X0 and X1 pins, an crystal oscillator (or a ceramic oscillator), and bypass capacitor to the ground become as
close as possible to each other. Furthermore, avoid wires to X0 and X1 pins crossing each other as much as
possible.
• Print circuit designing that surrounds X0 and X1 pins with grounding wires, which ensures stable operation,
is strongly recommended.

DS07-13728-5E
MB90455 Series
• Caution on Operations during PLL Clock Mode
• If the PLL clock mode is selected, the microcontroller attempt to be working with the self-oscillating circuit even
when there is no external oscillator or external clock input is stopped. Performance of this operation, however,
cannot be guaranteed.
• Sequence of turning on power of A/D converter and applying analog input
• Be sure to turn on digital power (Vcc) before applying signals to the A/D converter and applying analog input
signals (AN0 to AN7 pins).
• Be sure to turn off the power of A/D converter and analog input before turning off the digital power source.
• Be sure not to apply AVR exceeding AVcc when turning on and off. (No problems occur if analog and digital
power is turned on and off simultaneously.)
• Handling pins when A/D converter is not used
• If the A/D converter is not used, connect the pins under the following conditions: “AVcc=AVR=Vcc,” and
“Avss=Vss”
• Note on turning on power
• For preventing malfunctions on built-in step-down circuit, maintain a minimum of 50 μs of voltage rising time
(between 0.2 V and 2.7 V) when turning on the power.
• Stabilization of supply voltage
• A sudden change in the supply voltage may cause the device to malfunction even within the specified Vcc
supply voltage operating range. Therefore, the Vcc supply voltage should be stabilized.
For reference, the supply voltage should be controlled so that Vcc ripple variations (peak-to-peak values) at
commercial frequencies (50 Hz to 60 Hz) fall below 10% of the standard VCC supply voltage and the coefficient
of fluctuation does not exceed 0.1 V/ms at instantaneous power switching.

“FEFFFFH” is to read out “FF0000H” to “FFFFFFH”.
Note : When internal ROM is operating, F2MC-16LX allows viewing ROM data image on FF bank at upper-level of
00 bank. This function is called “mirroring ROM,” which allows effective use of C compiler small model.
F2MC-16LX assigns the same low order 16-bit address to FF bank and 00 bank, which allows referencing
table in ROM without specifying “far” using pointer.
For example, when accessing to “00C000H”, ROM data at “FFC000H” is accessed actually. However, because
ROM area of FF bank exceeds 48 Kbytes, viewing all areas is not possible on 00 bank image. Because
ROM data of “FF4000H” to “FFFFFFH” is viewed on “004000H” to “00FFFFH” image, store a ROM data table
in area “FF4000H” to “FFFFFFH”.

■ PERIPHERAL RESOURCES
1. I/O Ports
The I/O ports are used as general-purpose input/output ports (parallel I/O ports). The MB90455 series model
is provided with 5 ports (34 inputs). The ports function as input/output pins for peripheral functions also.
• I/O port functions
An I/O port, using port data resister (PDR), outputs the output data to I/O pin and input a signal input to I/O port.
The port direction register (DDR) specifies direction of input/output of I/O pins on a bit-by-bit basis.
The following summarizes functions of the ports and sharing peripheral functions :
• Port 1 : General-purpose input/output port, used also for PPG timer output and input capture inputs.
• Port 2 : General-purpose input/output port, used also for reload timer input/output and external interrupt input.
• Port 3 : General-purpose input/output port, used also for A/D converter activation trigger pin.
• Port 4 : General-purpose input/output port, used also for UART input/output.
• Port 5 : General-purpose input/output port, used also analog input pin.
• Port 1 pins block diagram (single-chip mode)

2. Time-Base Timer
The time-base time is a 18-bit free-run counter (time-base timer counter) that counts up in synchronization with
the main clock (dividing main oscillation clock by 2).
• Four choices of interval time are selectable, and generation of interrupt request is allowed for each interval time.
• Provides operation clock signal to oscillation stabilizing wait timer and peripheral functions.
• Interval timer function
• When the counter of time-base timer reaches an interval time specified by interval time selection bit
(TBTC:TBC1, TBC0), an overflow (carrying-over) occurs (TBTC: TBOF=1) and interrupt request is generated.
• If an interrupt by overflow is permitted (TBTC: TBIE=1), an interrupt is generated when overflow occurs (TBTC:
TBOF=1).
• The following four interval time settings are selectable :
Interval time of time-base timer
Count clock
Interval time
12
2 /HCLK (Approx. 1.0 ms)
2/HCLK (0.5 μs)
214/HCLK (Approx. 4.1 ms)
216/HCLK (Approx. 16.4 ms)

3. Watchdog Timer
The watchdog timer is a 2-bit counter that uses time-base timer or Watch timer as count clock. If the counter is
not cleared within an interval time, CPU is reset.
• Watchdog timer functions
• The watchdog timer is a timer counter that prevents runaway of a program. Once a watchdog timer is activated,
the counter of watchdog timer must always be cleared within a specified time of interval. If specified interval
time elapses without clearing the counter of a watchdog timer, CPU resetting occurs. This is the function of a
watchdog timer.
• The interval time of a watchdog timer is determined by a clock cycle, which is input as a count clock. Watchdog
resetting occurs between a minimum time and a maximum time specified.
• The output target of a clock source is specified by the watchdog clock selection bit (WTC: WDCS) in the Watch
timer control register.
• Interval time of a watchdog timer is specified by the time-base timer output selection bit/Watch timer output
selection bit (WDTC: WT1, WT0) in the watchdog timer control register.

DTP/external interrupt transfers an interrupt request generated by an external peripheral device or a data transmission request to CPU, generating external interrupt request and activating expanded intelligent I/O service.
• DTP/external interrupt function
An interrupt request input from external peripheral device to external input pins (INT7 to INT4), just as interrupt
request of peripheral device, generates an interrupt request. The interrupt request generates an external interrupt
and activates expanded intelligent I/O service (EI2OS).
If the expanded intelligent I/O service (EI2OS) has been disabled by interrupt control register (ICR: ISE=0),
external interrupt function is enabled and branches to interrupt processing.
If the EI2OS has been enabled, (ICR: ISE=1), DTP function is enabled and automatic data transmission is
performed by EI2OS. After performing specified number of data transmission processes, the process branches
to interrupt processing.

12. Address Matching Detection Function Outline
The address matching detection function checks if an address of an instruction to be processed next to a currentlyprocessed instruction is identical with an address specified in the detection address register. If the addresses
match with each other, an instruction to be processed next in program is forcibly replaced with INT9 instruction,
and process branches to the interrupt process program. Using INT9 interrupt, this function is available for
correcting program by batch processing.
• Address matching detection function outline
• An address of an instruction to be processed next to a currently-processed instruction of the program is always
retained in an address latch via internal data bus. By the address matching detection function, the address
value retained in the address latch is always compared with an address specified in detection address setting
register. If the compared address values match with each other, an instruction to be processed next by CPU
is forcibly replaced with INT9 instruction, and an interrupt process program is executed.
• Two detection address setting registers are provided (PADR0 and PADR1), and each register is provided with
interrupt permission bit. Generation of interrupt, which is caused by address matching between the address
retained in address latch and the address specified in address setting register, is permitted and prohibited on
a register-by-register basis.

Note : P35 and P36 are applicable only for products of MB90F455S/F456S/F457S, MB90455S/456S/457S.
• 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.
• 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.

Total error
: Analog variation that is recognized by an A/D converter.
: Deviation between a line across zero-transition line (“00 0000 00 0 0” ←→“00 0000 0001”)
and full-scale transition line (“11 1111 11 1 0” ←→ “11 1111 1111”) and actual conversion
characteristics.
: Deviation of input voltage, that is required for changing output code by 1 LSB, from an ideal
value.
: Difference between an actual value and an ideal value. A total error includes zero transition
error, full-scale transition error, and linear error.

7. Notes on A/D Converter Section
Use the device with external circuits of the following output impedance for analog inputs:
Recommended output impedance of external circuits are: Approx. 3.9 kΩ or lower (4.5 V ≤ AVcc ≤ 5.5 V)
(sampling period=2.00 μs at 16-MHz machine clock), Approx. 11 kΩ or lower (4.0 V ≤ AVcc < 4.5 V) (sampling
period=8.0 μs at 16-MHz machine clock).
If an external capacitor is used, in consideration of the effect by tap capacitance caused by external capacitors
and on-chip capacitors, capacitance of the external one is recommended to be several thousand times as high
as internal capacitor.
If output impedance of an external circuit is too high, a sampling period for an analog voltage may be insufficient.
