s DESCRIPTION
The MB90M405 series is a general-purpose 16-bit microcontroller, developed for applications requiring fluorescent display tube panel control. Each microcontroller is equipped with 60 highly voltage-resistant output pins, needed for fluorescent display control. The command structure inherits the same AT architecture as the F2MC-8L and F2MC-16L, in order to provide enhanced C-language support, improved extended/signed multiplication/division instructions in addressing mode, and enhanced bit processing. In addition, an onboard 32-bit accumulator allows long word processing. Note : F2MC stands for FUJITSU Flexible MicroController, and is a registered trademark of Fujitsu Limited.

s HANDLING DEVICES
This section contains important information on handling the device, regarding the following : * Do not exceed maximum rated voltage (to prevent latch-up) * Supply voltage stability * Power-on precautions * Treatment of unused pins * Treatment of A/D converter power supply pin * Notes on using external clock * Power supply pin * Sequence for applying power analog input of A/D converter * Output of high-voltage output pin (circuit types C & D) * Do not exceed maximum rated voltage (to prevent latch-up) * With a CMOS IC, if voltage above VCC or below VSS is applied to an output or input pin other than a medium/ high voltage resistance pin, or if voltage between VCC and VSS, but exceeding the rated voltage, is applied, a latch-up state could be generated. In the event of a latch-up, the power current will increase drastically, possibly destroying the chip due to overheating. For this reason, make sure not to exceed the maximum rating. * When applying or shutting off analog power, make sure that the analog power (AVCC) and analog input voltage do not exceed the digital power voltage (VCC) . * Supply voltage stability Even within the scope of operational protection for VCC power voltage, a sudden increase in power voltage could cause the unit to malfunction. For this reason, please stabilize the VCC power voltage. The standard for stabilizing voltage is a VCC ripple fluctuation (peak to peak value) of no more than 10% of standard VCC power voltage at commercial power frequencies (50 Hz to 60 Hz) , and an excess fluctuation rate of no more than 0.1 V/ms for instantaneous changes when switching power. * Power-on precautions When turning on the power, ensure that the power voltage (VCC) power-up time is at least 50 microseconds (0.2 V to 2.7 V) , in order to keep the built-in step-down circuit from malfunctioning. * Treatment of unused pins Leaving unused input pins free could cause permanent damage due to malfunctions and latch-ups. For this reason, set unused input pins to pull-up or pull-down via resistance of 2 k or more. Additionally, if there are unused I/O pins, either set them to output and leave them free, or set them to input and treat them as input pins. * Notes on using external clock When using an external clock, please drive pin X1 only, and free pin X1. An example of using an external clock is shown in the figure below:
X0 OPEN X1 MB90M405 series

MB90M405 Series
* Power supply pin * When there are multiple VCC/VSS, in order to prevent latch-ups and other malfunctions, then from design considerations, although pins of the same potential are connected device-internally, make sure to connect the VCC and VSS pins to power and grounds, in order to reduce unneeded radiation, and prevent strobe signal malfunctions due to rises in ground level. * Connect VCC and VSS to MB90M405 series devices from a current supply source at low impedance. * Connect an approximately 0.1 F capacitor as a bypass capacitor between the VCC and VSS, near the VCC and Vss pins, in order to combat power-source noise in MB90M405 series devices. * Crystal Oscillation Circuit * Noise to the X0 and X1 pins can cause MB90M405 series devices to malfunction. Design the printed circuit board so that pins X0 and X1, and the crystal oscillator (or ceramic oscillator) and the capacitor to the ground, are near pins X0 and X1, and not crossing the X0 and X1, or other wiring. * Stable operation can be expected from PCB artwork that surrounds pins X0 and X1 with grounds. * Sequence for applying power analog input of A/D converter * Always make sure to apply voltage to the digital power pin (VCC) before applying voltage to the A/D converter power pin (AVCC) and analog input pins (AN0 to AN15) . * When shutting off the power, shut off digital power (VCC) after shutting off A/D converter power and analog input. * If a port pin also used for analog input is used as an input port, make sure that the analog input voltage does not exceed AVCC (there is no problem with simultaneously applying and cutting analog and digital power) . * Pin handling when not using A/D converter * When not using the A/D converter, connect so that AVCC = VCC and AVSS = VSS. * Output of high-voltage resistance output pin (circuit types C & D) If using high voltage-resistance output (circuit types C & D) as the ordinary output port, when outputting "L" level, a value of pulldown for VKK pin voltage is output. In this case, the VKK level voltage is applied to the external circuit, so add a diode clamp circuit as shown in the figure below:
Diode clamp circuit Pch Pout
RKK VKK
* Notes on PLL clock mode If the oscillator is disconnected, or clock input stops, when the PLL clock is selected on the microcontroller, the microcontroller may continue to operate, using the freerun frequency of the PLL-internal self-exciting oscillation circuit. This operation is not guaranteed.

The purpose of the ROM mirror function is to use a small C compiler model. The lower 16-bit address of the FF bank is the same as the lower 16-bit address of the 00 bank. However, as the ROM area of the FF bank exceeds 48 Kbytes, a mirror image of all the data in the ROM area cannot be shown in the 00 bank. When using a small C compiler model, storing a data table in "FF4000H to FFFFFFH" allows a mirror image of the data table to be shown in "004000H to 00FFFFH". Consequently, it is possible to refer to the data table in the ROM area without declaring a far pointer. * When setting the ROM mirror function register, a mirror image of the data in the upper side of bank FF ("FF4000H to FFFFFFH") can be seen in the upper side of bank 00 ("004000H to 00FFFFH") . * See "s PERIPHERAL FUNCTIONS 15. ROM Mirror Function Selection Module" for details on setting the ROM mirror function.

s PERIPHERAL FUNCTIONS
1. I/O Ports
There are a maximum of 26 I/O ports (parallel I/O ports) , which are also used as resource I/O pins (peripheral function I/O pins) . * I/O Port Functions There are two kinds of I/O port : port direction registers (DDRs) and port data registers (PDRs) . The port direction register (DDR) can set port pin I/O at the bit level. The port data register (PDR) sets output data to the port pins. If the port direction register (DDR) sets the I/O port pin to input, the port pin level value can be read by reading the port data register (PDR) . If the port direction register (DDR) sets the I/O port pin to output, the port data register (PDR) value is output to the port pin. Below is a list of the functions of each I/O port, and dual use resources. * Port 8 : I/O port/resource use (external interrupt input pin, ICU, UART) * Port 9 : I/O port/resource use (I2C, serial I/O ch3) * Port A : I/O port/resource use (A/D converter, time clock output) * Port B : I/O port/resource use (A/D converter, serial I/O ch2, external interrupt input pin, reload timer ch0) I/O Port Name Port 8 Input Format Output Function Format I/O Port P80 to P87 CMOS P87 P86 SC1 PA6 AN6 PB6 P85 SI1 PA5 AN5 PB5 SO2 TO P84 SO0 PA4 AN4 PB4 SC2 TIN P83 SC0 PA3 AN3 PB3 P82 SI0 PA2 AN2 PB2 P81 IC1 INT1 P91 SCL SC3 PA1 AN1 PB1 P80 IO0 INT0 P90 SDA SO3 PA0 AN0 TMCK PB0 AN8

2. Serial I/O
Serial I/O allows data transfer via synchronization with a clock consisting of two 8-bit channels. In addition, LSB first or MSB first can be selected for data transfer. * Overview of Serial I/O There are two types of serial I/O operation mode : * Internal shift clock mode Data is transferred in synchronization with internal clock (communication prescaler) * External shift clock mode Data is transferred in synchronization with clock input from external pin (SC) . In this mode, it is also possible to transfer data via CPU instructions (port inversion instruction execution timing) by manipulating the generalpurpose port sharing the external pin (SC) . * Block Diagram of Serial I/O

3. Timebase Timer
The timebase timer is a 18-bit free-run counter that counts up in synchronization with the main clock. The timer has an interval timer function capable of setting four different intervals, and a function for supplying clocks to the oscillator stabilization standby timer, watchdog timer, and time clock output circuit. * Interval timer function The interval timer function sends an interrupt request at set intervals. * When the timebase timer counter's interval timer counter overflows, an interrupt request is output. * One of four intervals can be set for the interval timer. Main Clock Cycle Interval Times 212/HCLK (Approx. 0.97 ms) 2/HCLK (0.5 s) 214/HCLK (Approx. 3.90 ms) 216/HCLK (Approx. 15.62 ms) 219/HCLK (Approx. 125.00 ms) HCLK : Oscillator clock frequency Values in parentheses ( ) are when oscillator clock frequency is 4.194 MHz. * Clock Supply Function The clock supply function supplies operation clocks to the oscillation stabilization standby timer and some peripheral functions. Clock Supply Destination Clock Cycles 213/HCLK (Approx. 1.95 ms) Oscillation stabilization standby 215/HCLK (Approx. 7.81 ms) 218/HCLK (Approx. 62.50 ms) 212/HCLK (Approx. 0.97 ms) Watchdog timer 214/HCLK (Approx. 3.90 ms) 216/HCLK (Approx. 15.62 ms) 219/HCLK (Approx. 125.00 ms) HCLK : Oscillator clock frequency Values in parentheses ( ) are when oscillator clock frequency is 4.194 MHz. Reference : Immediately after oscillation begins, the oscillation cycles are unstable; oscillation stabilization standby is a rough measure of the time for oscillation to become stable.

4. Watchdog Timer
The watchdog timer is a two-bit timer that uses the output of the timebase timer as a count clock. When the watchdog timer is started, if it is not cleared within the set interval, the CPU is reset. * Watchdog Timer Function * The watchdog timer detects runaway programs. When the watchdog timer is started, it must be cleared within a set interval. If a program enters an infinite loop, or for some other reason the watchdog timer is not cleared within the minimum time, a watchdog reset is generated to the CPU, sending it to a reset state. The watchdog timer interval is set by the interval time setting bits (WT1 and WT0) of the watchdog timer control register (WDTC) . WT1 0 0 1 1 WT0 0 1 0 1 Interval Times Minimum* Approx. 3.58 ms Approx. 14.33 ms Approx. 57.23 ms Maximum* Approx. 4.61 ms Approx. 18.3 ms Approx. 73.73 ms Oscillator clock cycles 214 211 cycles 216 213 cycles 218 215 cycles 221 218 cycles
Approx. 458.75 ms Approx. 589.82 ms
* : When oscillator clock frequency is 4.19 MHz. Reference : After the watchdog timer is started, it can be halted via a power-on reset, or a reset by the watchdog timer. While an external reset, internal reset, setting the watchdog control bit (WTE) of the watchdog timer control register (WDTC) , or going to sleep or stop mode can clear the watchdog timer, these actions will not change the watchdog function setting, or halt the watchdog timer. Note: The watchdog timer is made up of a two-bit timer that counts the carry signal of the timebase timer. Because the watchdog timer uses the carry signal of the timebase timer, if the timebase timer is cleared, then the watchdog reset interval may be longer than the set time. * Block Diagram of Watchdog Timer

5. 16-bit Reload Timer
The MB90M405 series has 3 built-in 16-bit reload timer channels. They can be configured with the following clock modes and counter operation modes : * * * * * * * Clock Modes Internal Clock Mode : In this mode, the timer counts down in synchronization with the internal clock Event Count Mode : In this mode, the timer counts down in accordance with external input pulses Counter Operation Modes Reload Mode : In this mode, the count setting is reloaded, and the count is repeated One-shot Mode : In this mode, the count is halted due to an underflow 16-bit Reload Timer Operation Modes Clock Mode Counter Operation Mode Operation Mode Reload mode Internal Clock Mode Event Count Mode (External Clock Mode) * Internal Clock Mode When the count clock setting bits (CSL1, CSL0) of the timer control status register (TMCSR) are set to "00B", "01B", or "10B", the mode is set to internal clock mode. In internal clock mode, the following operation modes can be set : * Software trigger operation If the count enable bit (CNTE) of the timer control status register (TMCSR) is set to "1", setting the software trigger bit (TRG) to "1" will initiate count operation. * External trigger input operation If the count enable bit (CNTE) of the timer control status register (TMCSR) is set to "1", then when a valid edge (rising, falling, or both edges can be set) set beforehand in the operation mode setting bits (MOD2, MOD1, MOD0) is input to the TIN pin, count operation is initiated. * External gate input operation If the count enable bit (CNTE) of the timer control status register (TMCSR) is set to "1", then count operation is conducted while a valid gate input level ("L" or "H" can be set) set beforehand in the operation mode setting bits (MOD2, MOD1, MOD0) is input to the TIN pin. * Event Count Mode (External Clock Mode) When the count clock setting bits (CSL1, CSL0) of the timer control status register (TMCSR) are set to "11B", the mode is set to event count mode (external clock) . If the count enable bit (CNTE) is set to "1", then when a valid edge (rising, falling, or both edges can be set) set in the operation mode setting bits (MOD2, MOD1, MOD0) is input to the TIN pin, count operation is initiated. If an external clock is input at set intervals, then it can also be used as an interval timer.

* Counter Operation * Reload mode When the 16-bit down counter underflows ("0000H" to "FFFFH") , the value of the 16-bit reload register (TMRLR) is loaded into the 16-bit down counter, and count operation is conducted. In addition, when an underflow occurs an interrupt request is output, so this can also be used as an interval timer. It is possible to output the inverted toggle waveform from the TO pin with each underflow.

The 16-bit I/O timer can perform dual independent waveform output, input pulse width measurement, and external clock cycle measurement, based on the 16-bit freerun timer. * 16-bit freerun timer (1 channel) The 16-bit freerun timer is made up of a 16-bit up counter (timer data register (TCDT) ) , timer control status register (TCCS) , and prescaler. The counter output value of the 16-bit freerun timer is used as the base timer for output comparison and input capture. * Counter operation clock (4 different settings available) 4 internal clock types : /4, /16, /32, /64 : Machine clock frequency * Interrupt An interrupt can be output to the CPU when the counter value overflows, or when it matches the value of comparison register 0. * Initialize When a reset is input, if the software reset bit is cleared to "0", or if the values of comparison register 0 and the freerun timer count match, the counter value can be initialized to "0000H". * Output compare (1 channel) The output comparison module consists of a 1-channel 16-bit comparison register, and control register. If the value of the 16-bit freerun timer and that of the compare register match, an interrupt request can be output to the CPU. * Input capture (2 channels) The input capture module consists of a capture register and a control register. Both support two independent external input pin channels. The capture register can store the value of the 16-bit freerun timer. Additionally, the register can detect signal input edges from external pins, and simultaneously output interrupts to the CPU. * The detection edge of the external input signal can be configured (rising edge, falling edge, both edges) * The two input capture channels can operate independently Interrupts can be output upon detection of a valid edge in an external input signal * Input capture interrupts start the extended intelligent I/O service

8. DTP/External Interrupt Circuit
The DTP (Data Transfer Peripheral) /external interrupt circuit detects interrupt requests input from the external interrupt input pin, and outputs interrupt requests. * DTP/External Interrupt Function The DTP/external interrupt circuit outputs interrupt requests upon detection of an edge input from the external interrupt input pin, or a level signal. Interrupt requests are accepted by the CPU, and if extended intelligent I/O service (EI2OS) is enabled, the CPU conducts automated data transfer (DTP function) via EI2OS, then branches into an interrupt processing routine. If EI2OS is disabled, the CPU branches into an interrupt processing routine, without starting automated data transfer (DTP function) via EI2OS. External Interrupt Function Input pins Interrupt conditions Interrupt number Interrupt control Interrupt flag Processing selection Operation 4 channels (P80/INT0, P81/INT1, PB6/INT2, PB7/INT3) The level or edge to detect can be set independently for each pin in the detection level setup register (ELVR) "L" level/"H" level input #11 (0BH), #13 (0DH) , #16(10H) Enable/disable interrupt request output in the DTP/external interrupt enable register (ENIR) The DTP/interrupt factor register (EIRR) stores interrupt conditions.

Sudden changes in the power supply voltage may cause a power-on reset. The recommended practice if you wish to change the power supply voltage while the device is operating is to raise the voltage smoothly as shown below. Also, changes to the supply voltage should be performed when the PLL clock is not in use. The PLL clock may be used, however, if the rate of voltage change is 1 V/s or less.
VCC
Recommended rate of voltage rise is 50 mV/ms or less.
