DESCRIPTIONS
The FUJITSU MICROELECTRONICS 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 MICROELECTRONICS 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
* 16-bit input capture (4 channels) Detects rising, falling, or both edges. 16-bit capture register x 4 Pin input edge detection latches the 16-bit free-run timer counter value, and generates an interrupt request. * 16-bit reload timer (2 channels) 16-bit reload timer operation (select toggle output or one-shot output) Event count function selection provided * Watch timer (main clock) Operates directly from oscillator clock.

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 semiconductor 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 power supply (VCC) 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 frequencies (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 poweron should be attained within 50 s (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 k. 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 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 the following figure.

Sample external clock connection DS07-13711-5E 13
MB90420G/425G Series
* Power supply pins Devices are designed to prevent problems such as latchup when multiple VCC and 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 VCC power 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 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 F 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 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 (DVCC, DVSS) Always apply power to high-current output buffer pins (DVCC, 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 (DVCC, DVSS) 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 DS07-13711-5E
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 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 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 ( x 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 ( x 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 , /2, /4, /8, /16, /32, /64, /128 where 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. (3) Block diagram

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) . (1) 16-bit Reload timer operating modes Clock mode Counter mode Reload mode Internal clock mode Event count mode (external clock mode) (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.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 "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 inverts at each underflow can be output from the TOT0/1 pin.

6. PPG Timer
The PPG timer consists of a prescaler, one 16-bit down-counter, 16-bit data register with buffer for period setting, and 16-bit compare register with buffer for duty setting, plus pin control circuits. The timer can output pulses synchronized with an externally input soft trigger. The period and duty of the output pulse can be adjusted by rewriting the values in the two 16-bit registers. (1) PWM function Programmable to output a pulse, synchronized with a trigger. Can also be used as a D/A converter with an external circuit. (2) One-shot function Detects the edge of a trigger input, and outputs a single pulse. (3) Pin control * Set to "1" at a duty match (priority) . * Reset to "0" at a counter borrow event * Has a fixed output mode to output a simple all "L" ( or "H") signal. * Polarity can be specified (4) 16-bit down counter * Select from four types of counter operation clocks. Four internal clocks (, /4, /16, /64) cycles. * The counter value can be initialized to "FFFFH" at a reset or counter borrow event. (5) Interrupt requests * Timer startup * Counter borrow event (period match) * Duty match event * Counter borrow event (period match) or duty match event (6) Multiple channels can be set to start up at an external trigger, or to restart during operation.

8. DTP/External Interrupt Circuit
The DTP (Data transfer peripheral) /external interrupt circuit is located between an externally connected peripheral 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. External interrupt Input pins DTP function

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 s (at machine clock frequency of 16 MHz, including sampling time) . * Minimum sampling time is 3.75 s (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 Conversion mode Single conversion operation Single conversion mode

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 s. 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

Extreme variations in voltage supply may activate a power-on reset. As the illustration below shows, when varying supply voltage during operation the use of a smooth voltage rise with suppressed fluctuation is recommended. Also in this situation, the PLL clock on the device should not be used, however it is permissible to use the PLL clock during a voltage drop of 1V/s or less.

(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 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. * 10-bit A/D converter conversion characteristics
