■ DESCRIPTIONS

The FUJITSU MB90420G/425G Series is a 16-bit general purpose high-capacity microcontroller designed for

vehicle meter control applications etc.

The instruction set retains the same AT architecture as the FUJITSU original F²MC-8L and F²MC-16L series, with

further refinements including high-level language instructions, expanded addressing mode, enhanced (signed)

multipler-divider computation and bit processing.

In addition, a 32-bit accumulator is built in to enable long word processing.

■ FEATURES

■ 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 V^CCat 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 (AV^CC, 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 power supply (V^CC) is switched on, the analog power (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 prevent abnormal operation of the internal built-in step-down circuits, voltage 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, they may cause abnormal operation or latchup which may 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 AV^CC= VCC, and AVSS = AVRH = VSS.

• Use of external clock signals

Even when an external 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 Figure 3.

MB90420G/425G Series

• Power supply pins

Devices are designed to prevent problems such as latchup when multiple V^CCand VSS supply pins are used, by

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 V^CCpower supply pins must have the same potential. All VSS power supply pins

should be handled in the same way. If there are multiple VCC or VSS systems, the device will not operate properly

even within the warranted operating range.

Power supply input pins (VCC/VSS)

In addition, care must be given to connecting the V^CCand 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 (AV^CC, 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 switched 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 ports, 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 (DV^CC, DV^SS)

Always apply power to high-current output buffer pins (DV^CC, DVSS) after the digital power supply (VCC) is turned

on. Also when switching power off, always shut off the power supply to the high-current output buffer pins (DV^CC,

DV^SS) before switching off the digital power supply (VCC) . (There will be no problem if high-current output buffer

pins and digital power supplies are turned off and on at the same time.)

Even when high-current output buffer pins are used as general purpose ports, the power for 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.

14

MB90420G/425G Series

• Precautions for 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 leave

the X1A pin open.

• Notes on during operation of 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.

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 enable efficient use of

small C compiler models. The lower 16-bit address for the FF bank will be assigned 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 00C000^H, 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 FFFFFFH 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.

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 carry 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 clock

(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 provides 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 fixed intervals. 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 external 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 internal 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 “0000^H” 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 clock 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 available. 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) .

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.Trigger input at the TRG bit is normally valid with an external 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 (rising, 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 “0000^H” 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 inverts at each underflow can be

output from the TOT0/1 pin.

In down count operation, the count stops when an underflow event (transition from “0000^H” to “FFFFH”) occurs.

This function can generate an interrupt at each underflow. While the counter is operating, a rectangular wave

form indicating that the count is in progress can be output form the TOT0 and TOT1 pins.

8. DTP/External Interrupt Circuit

The DTP (Data transfer peripheral) /external interrupt circuit is located between an externally connected periph-

eral device and the F²MC-16LX CPU and sends interrupt requests or data transfer requests generated from the

peripheral device to the CPU, thereby generating external interrupt requests or starting the expanded intelligent

I/O services (EI²OS) .

(1) DTP/external interrupt function

The DTP/external interrupt function uses a signal input from the DTP/external 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.

9. 8/10-bit A/D Converter

The 8/10-bit A/D converter has functions for using RC sequential comparator conversion format to convert analog

input voltage into 10-bit or 8-bit digital values. The input signal is selected from 8-channel analog input pins, and

the conversion start can be selected from three types : by software, 16-bit reload timer 1 or a trigger input from

an external signal pin.

(1) 8/10-bit A/D converter functions

The A/D converter takes analog voltage signals (input voltage) input at analog input pins, and converts these to

digital values, providing the following features.

• Minimum conversion time is 6.13 µs (at machine clock frequency of 16 MHz, including sampling time) .

• Minimum sampling time is 3.75 µs (at machine clock 16 MHz)

• The conversion method is an RC sequential conversion in comparison with a sample hold circuit.

• Either 10-bit or 8-bit resolution can be selected.

• The analog input pin can select from 8 channels by a program setting.

• At completion of A/D conversion, an interrupt request can be generated, or EI²OS can be started.

• Because the conversion data protection function operates in an interrupt enabled state, no data is lost even

in continuous conversion.

• The conversion start source may be selected from : software, 16-bit reload timer 1 (rising edge) , or external

trigger input (falling edge) .

Three conversion modes are available

13. Low voltage/Program Looping Detection Reset Circuit

The Low voltage detection reset circuit is a function that monitors power supply voltage in order to detect when

a voltage drops below a given voltage level. When a low voltage condition is detected, an internal 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

Detection voltage

4.0 V ± 0.3 V

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 internal 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.

Interval duration

2²⁰/FC (Approx. 262 ms *)

* : 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 clock mode

*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 I^CLAMPrating

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”.

*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 V^CCpin, 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 :

• Input/Output equivalent circuits

(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 deviation between actual conversion characteristics and a straight line connecting the device’s

zero transition point (00 0000 0000 ←→ 00 0000 0001) and full scale transition point (11 1111 1110 ←→ 11
