■HANDLING DEVICES
Precautions for Handling Semiconductor Devices
• Strictly observe maximum rated voltages (prevent latchup)
When CMOS integrated circuit devices are subjected to applied voltages higher than VCC at input and output
pins other than medium- and high-withstand voltage pins, or to voltages lower than VSS, or when voltages in
excess of rated levels are applied between VCC and VSS, a phenomenon known as latchup can occur. In a latchup
condition, supply current can increase dramatically and may destroy semiconductor elements. In using semi-
conductor devices, always take sufficient care to avoid exceeding maximum ratings.
Also care must be taken when power to analog systems is switched on or off, to ensure that the analog power
supply (AVCC, AVRH) , analog input and dedicated power supply for the high current output buffer pins (DVCC)
do not exceed the digital power supply (VCC) .
Once the digital pow er supply (VCC) is switched on, the analog po wer (AVCC,AVRH) and dedicated power supply
for the high current output buffer pins (DVCC) may be turned on in any sequence.
• Stable supply voltage
Even within the warranted operating range of VCC supply voltage, sudden fluctuations in supply voltage can
cause abnormal operation. The recommended stability for ripple fluctuations (P-P values) at commercial fre-
quencies (50 Hz to 60 Hz) should be within 10% of the standard VCC value, and voltage fluctuations that occur
during switching of power supplies etc. should be limited to transient fluctuation rates of 0.1 V/ms or less.
• Power-on procedures
In order to pre vent abnormal operation of the internal b uilt-in step-down circuits, v oltage rise time during power-
on should be attained within 50 µs (0.2 V to 2.7 V) .
• Treatment of unused pins
If unused input pins are left open, the y ma y cause abnormal operation or latchup which ma y lead to permanent
damage to the semiconductor. Any such pins should be pulled up or pulled down through resistance of at least
2 kΩ.
Any unused input/output pins should be left open in output status, or if found set to input status, they should be
treated in the same way as input pins.
Any unused output pins should be left open.
• Treatment of A/D converter power supply pins
Even if the A/D converter is not used, pins should be connected so that AVCC = VCC, and AVSS = AVRH = VSS.
• Use of external clock signals
Even when an exter nal clock is used, a stabilization period is required following a power-on reset or release
from sub clock mode or stop mode . Also, when an external clock is used it should drive only the X0 pin and the
X1 pin should be left open, as shown in the following figure.

• Power supply pins
De vices are designed to prevent prob lems such as latchup when m ultiple VCC and VSS supply pi ns are used, b y
providing internal connections between pins having the same potential. However, in order to reduce unwanted
radiation, and to prevent abnormal operation of strobe signals due to rise in ground level, and to maintain total
output current ratings, all such pins should always be connected externally to power supplies and ground.
As shown in figure below, all VCC power supply pins must have the same potential. All VSS power supply pins
should be handled in the same wa y. If there are multiple VCC or VSS systems, the de vice will not operate properly
even within the warranted operating range.
In addition, care must be giv en to connecting the VCC and VSS pins of this device to a current source with as little
impedance as possible. It is recommended that a bypass capacitor of 1.0 µF be connected between VCC and
VSS as close to the pins as possible.
• Proper sequence of A/D converter power supply analog input
A/D converter power (AVCC, AVRH) and analog input (AN0-AN7) must be applied after the digital power supply
(VCC) is switched on. When power is shut off, the A/D converter power supply and analog input must be cut off
before the digital power supply is sw itched on (VCC) . In both power-on and shut-off, care should be taken that
AVRH does not exceed AVCC. Even when pins which double as analog input pins are used as input por ts, be
sure that the input voltage does not exceed AVCC. (There is no problem if analog power supplies and digital
power supplies are turned off and on at the same time.)
• Handling the power supply for high-current output buffer pins (DVCC, DVSS)
Alwa ys apply po wer to high-current output b uffer pins (DVCC, DVSS) after the digital power supply (VCC) is turned
on. Also when s witching power off, alwa ys shut off the pow er supply to the high-current output buff er pins (D VCC,
DVSS) bef ore s witching off the digital po w er supply (VCC) . (There will be no prob lem if high-current output b uffer
pins and digital power supplies are turned off and on at the same time.)
Even when high-current output b uff er pins are used as general purpose ports, the power f or high current output
buffer pins (DVCC, DVSS) should be applied to these pins.
• Pull-up/pull-down resistance
The MB90420G/425G series does not support internal pull-up/pull-down resistance. If necessary, use external
components.

• Precautions f or when not using a sub clock signal.
If the X0A and X1A pins are not connected to an oscillator, apply pull-down treatment to the X0A pin and lea ve
the X1A pin open.
• Notes on during operation of PLL clock mode
If the PLL clock mode is selected, the microcontroller attempt to be w orking with the self-oscillating circuit e v en
when there is no external oscillator or external clock input is stopped. Performance of this operation, however,
cannot be guaranteed.

■MEMORY MAP
Note : To select models without the ROM mirror function, see the “ROM Mirror Function Selection Module.” The
image of the ROM data in the FF bank appears at the top of the 00 bank, in order to enab le efficient use of
small C compiler models. The lower 16-bit address for the FF bank will be assign ed to the same address,
so that tables in ROM can be referenced without declaring a “far” indication with the pointer. For example
when accessing the address 00C000H, the actual access is to address FFC000H in ROM. Here the FF bank
ROM area exceeds 48 KB, so that it is not possible to see the entire area in the 00 bank image. Therefore
because the ROM data from FF4000H to FFFFFF H will appear in the image from 004000H to 00FFFFH, it is
recommended that the ROM data table be stored in the area from FF4000H to FFFFFFH.

■PERIPHERAL FUNCTIONS
1. I/O Ports
The I/O ports function is to send data from the CPU to be output from I/O pins and load input signals at the I/O
pins into the CPU, according to the port data register (PDR) . Port input/output at I/O pins can be controlled in
bit units by the port direction register (DDR) as required. The following list shows each of the functions as well
as the shared peripheral function for each port.
• Port 0 : General purpose I/O port, shared with peripheral functions (external interrupt/UART/PPG)
• Port 1 : General purpose I/O port, shared with peripheral functions (PPG/reload timer/watch timer/ICU)
• Port 3 : General purpose I/O port, shared with peripheral functions (LCD)
• Port 4 : General purpose I/O port, shared with peripheral functions (LCD)
• Port 5 : General purpose I/O port, shared with peripheral functions (External interrupt/CAN/SG)
• Port 6 : General purpose I/O port, shared with peripheral functions (A/D converter)
• Port 7 : General purpose I/O port, shared with peripheral functions (Stepping motor controller)
• Port 8 : General purpose I/O port, shared with peripheral functions (Stepping motor controller)
• Port 9 : General purpose I/O port, shared with peripheral functions (LCD)

2. Watchdog Timer/Time Base Timer/Watch Timer
The watchdog timer, timer base timer, and watch timer have the following circuit configuration.
• Watchdog timer : Watchdog counter, control register, watchdog reset circuit
• Time base timer : 18-bit timer, interval interrupt control circuit
• Watch timer : 15-bit timer, interval interrupt control circuit
(1) Watchdog timer function
The watchdog timer is composed of a 2-bit watchdog counter that uses the carr y signal from the 18-bit time
base timer or 15-bit watch timer as a clock source, plus a control register and watchdog reset control circuit.
After startup, this function will reset the CPU if not cleared within a given time.
(2) Time base timer function
The time base timer is an 18-bit free-run counter (time base counter) synchronized with the internal count cloc k
(base oscillator divided by 2) , with an interval timer function providing a selection of four interval times. Other
functions include a timer output for an oscillator stabilization wait time and clock feed to the watchdog timer or
other operating clocks. Note that the time base timer uses the main clock regardless of the setting of the MCS
bit or SCS bit in the CKSCR register.
(3) Watch timer function
The watch timer pro v ides functions including a clock source for the watchdog timer, a sub clock base oscillator
stabilization wait timer, and an interval timer to generate an interrupt at fix ed interv als. Note that the watch timer
uses the sub clock regardless of the setting of the MCS bit or SCS bit in the CKSCR register.

3. Input Capture
This circuit is composed of a 16-bit free-run timer and four 16-bit input capture circuits.
(1) Input capture ( × 4)
The input capture circuits consist of four independent external input pins and corresponding capture registers
and control registers. When the specified edge of the e xternal signal input (at the input pin) is detected, the value
of the 16-bit free-run timer is saved in the capture register, and at the same time an interrupt can also be
generated.
• The valid edge (rising edge, falling edge, both edges) of the external signal can be selected.
• The four input capture circuits can operate independently.
• The interrupt can be generated from the valid edge of the external input signal.
(2) 16-bit free-run timer ( × 1)
The 16-bit free-run timer is composed of a 16-bit up-counter, control register, 16-bit compare register, and
prescaler. The output values from this counter are used as the base time for the input capture circuits.
• The counter clock operation can be selected from 8 options. The eight inter nal clock settings are φ, φ/2, φ/4,
φ/8, φ/16, φ/32, φ/64, φ/128 where φ represents the machine clock cycle.
• Interrupts can be generated from overflow events, or from compare match events with the compare register.
(Compare match operation requires a mode setting.)
• The counter value can be initialized to “0000H” by a reset, soft clear, or a compare match with the compare
register.

4. 16-bit Reload Timer
The 16-bit reload timer can either count down in synchronization with three types of internal clock signals in
internal cloc k mode, or count down at the detection of the designated edge of an external signal. The user may
select either function. This timer defines a transition from 0000H to FFFFH as an underflow event. Thus an
underflow occurs when counting from the value [Reload register setting + 1].
A selection of two counter operating modes are a vailab le. In reload mode, the counter is reset to the count value
and continues counting after an underflow, and in one-shot mode the count stops after an underflow. The counter
can generate an interrupt when an underflow occurs, and is compatible with the expanded intelligent I/O services
(EI2OS) .
(1) 16-bit Reload timer operating modes
(2) Internal clock mode
One of three input clocks is selected as the count clock, and can be used in one of the following operations.
• Soft trigger operation
When “1” is written to the TRG bit in the timer control status register (TMCSR0/1) , the count operation
starts.Tr igger input at the TRG bit is normally valid with an ex ternal trigger input, as well as an external gate
input.
• External trigger operation
Count operation starts when a selected edge (rising, falling, both edges) is input at the TIN0/1 pin.
• External gate input operation
Counting continues as long as the selected signal level (“L” or “H”) is input at the TIN0/1 pin.
(3) Event count mode (External clock mode)
In this mode a down count event occurs when a selected valid edge (r ising, falling, both edges) is input at the
TIN0/1 pin. This function can also be used as an interval timer when an external clock with a fixed period is used.
(4) Counter operation
• Reload mode
In down count operation, when an underflow event (transition from “0000H” to “FFFFH”) occurs, the set count
value is reloaded and count operation continues. The function can be used as an interval timer by generating
an interrupt request at each underflow event. Also, a toggle waveform that inver ts at each underflow can be
output from the TOT0/1 pin.

8. DTP/External Interrupt Circuit
The DTP (Data transf er peripheral) /e xternal interrupt circuit is located between an e xternally connected periph-
eral de vice and the F2MC-16LX CPU and sends interrupt requests or data transf er requests generated from the
peripheral de vice to the CPU, thereby generating e xternal interrupt requests or starting the expanded intelligent
I/O services (EI2OS) .
(1) DTP/external interrupt function
The DTP/e xternal interrupt function uses a signal input from the DTP/e xternal interrupt pin as a startup source.
And it is accepted by the CPU by the same procedure as a normal hardware interrupt, and can generate an
external interrupt or start the expanded intelligent I/O service (EI2OS) .
When the interrupt is accepted by the CPU, if the corresponding expanded intelligent I/O service (EI2OS) is
prohibited the interrupt operates as an external interrupt function and branches to an interrupt routine. If the
EI2OS is permitted the interrupt functions as a DTP function, using EI2OS for automatic data transfer, then
branching to an interrupt routine after the completion of the specified number of data transfers.

13. Low voltage/Program Looping Detection Reset Circuit
The Low v oltage detection reset circuit is a function that monitors po wer supply voltage in order to detect when
a voltage drops below a given voltage level. When a low voltage condition is detected, an inter nal reset signal
is generated.
The Program Looping detection reset circuit is a count clock with a 20-bit counter that generates an internal
reset signal if not cleared within a given time after startup.
(1) Low voltage detection reset circuit
When a low voltage condition is detected, the low voltage detection flag (LVRC : LVRF) is set to “1” and an
internal reset signal is output.
Because the low voltage detection circuit continues to operate even in stop mode, detection of a low voltage
condition generates an internal reset and releases stop mode.
During an inter nal RAM write cycle, an internal reset is generated after the completion of writing. During the
output of this internal reset, the reset output from the low voltage detection circuit is suppressed.
(2) Program Looping detection reset circuit
The Program Looping detection reset circuit is a counter that prevents program looping. The counter starts
automatically after a power-on reset, and must be continually cleared within a given time. If the given time interval
elapses and the counter has not been cleared, a cause such as infinite program looping is assumed and an
internal reset signal is generated. The internal reset generated form the Program Looping detection circuit has
a width of 5 machine cycles.
* : This value assumes an oscillation clock waveform of 4 MHz.
During recovery from standby mode the detection period is the maximum interval plus 20 µs.
This circuit does not operate in modes where CPU operation is stopped.
The Program Looping detection reset circuit counter is cleared under any of the following conditions.
1. Writing “0” to the LVRC register CL bit
2. Internal reset
3. Main oscillation clock stop
4. Transition to sleep mode
5. Transition to time base timer mode or watch mode

16. Address Match Detect Function
If the address setting is the same as the address detection register, an INT9 instruction is executed. The
integrated address match detection function can be implemented by processing the INT9 interrupt service
routine.
Two address registers are used, each with its own compare enable bit. When there is a match between the
address register and program counter, and the compare enable bit is set to “1” , the INT9 instruction is forcibly
executed by the CPU.

■ELECTRICAL CHARACTERISTICS
1. Absolute Maximum Ratings
*1 : The parameter is based on VSS = AVSS = DVSS = 0.0 V.
*2 : AVCC, AVRH and DVCC shall never exceed VCC.
Also, AVRH shall never exceed AVCC.
*3 : The maximum current to/from and input is limited by some means with extenal components, the ICLAMP rating
supersedes the VI rating.
*4 : Maximum output current is defined as the peak value of the current of any one of the corresponding pins.
*5 : Average output current is defined as the value of the average current flowing over 100 ms at any one of the
corresponding pins. The “average value” can be calculated from the formula of “operating current” times
“operating factor”. (Continued)

*6 : Average total output current is defined as the value of the average current flowing over 100 ms at all of the
corresponding pins. The “average value” can be calculated from the formula of “operating current” times
“ operating factor”.
*7 : • Applicable to pins : P00 to P07, P10 to P15, P50 to P57, P70 to P77, P80 to P87
• Use within recommended operating conditions.
• Use at DC voltage (current) .
• The + B signal should always be applied with 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 current 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 (LCD drive pins, comparator input pins, etc.) cannot accept + B
signal input.
• Sample recommended circuits :
WARNING: Semiconductor devices can be permanently damaged by application of stress (voltage, current,
temperature, etc.) in excess of absolute maximum ratings. Do not exceed these ratings.

• Notes of the external impedance of the analog input and its sampling time
•A/D converter with sample and hold circuit. If the external impedance is too high to keep sufficient sampling
time, the analog voltage charged to the internal sample and hold capacitor is insufficient, adversely affecting
A/D conversion presicion.
•To satisfy the A/D conversion precision standard, consider the relationship between the external impedance
and minimum sampling time and either adjust the resistor value and operating frequency or decrease the
external impedance so that the sampling time is longer than the minimum value.
•If the sampling time cannot be sufficient, connect a capacitor of about 0.1 µF to the analog input pin.
•About errors
As |AVRH| becomes smaller, values of relative errors grow larger.

(2) Definition of terms
• Resolution
Indicates the ability of the A/D converter to discriminate in analog conversion.
10-bit resolution indicates that analog voltage can be resolved into 210 = 1024 levels.
• Total error
Expresses the difference between actual and logical values. It is the total value of errors that can come from
offset error, gain error, non-linearity error and noise.
• Linearity error
Expresses the de viation between actual con version char acteristics and a straight line connecting the device’s
zero tr ansition point (00 0000 0000 ←→ 00 0000 0001) and full scale transition point (11 1111 1110 ←→ 11
1111 1111) .
• Differential linearity error
Expresses the deviation of the logical value of input voltage required to create a variation of 1 LSB in output code.
