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, DVCC) and analog input do not exceed the digital power supply (VCC) . Once the digital power supply (VCC) is switched on, the analog power (AVCC,AVRH,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 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 input 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. Also 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. * 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. 13 MB90420G/5G (A) Series * 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. X0 X1 OPEN MB90420G/425G (A) Series Sample external clock connection * 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 4, 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. VCC VSS VCC VSS VSS VCC VCC VSS VSS VCC 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.) 14 MB90420G/5G (A) Series * 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/5G series does not support internal pull-up/pull-down resistance. If necessary, use external components. * 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. 15 MB90420G/5G (A) Series BLOCK DIAGRAM P57/SGA P56/SGO/FRCK P55/RX0 P54/TX0 P53/INT3 P52/INT2 (/TX1) P51/INT1 (/RX1) P50/INT0/ADTG P00/SIN0/INT4 P01/SOT0/INT5 P02/SCK0/INT6 P03/SIN1/INT7 P04/SOT1 P05/SCK1/TRG P06/PPG0/TOT1 P07/PPG1/TIN1 Clock control circuit CPU F2MC-16LX core RAM Interrupt controller ROM Low voltage detector reset Sound generator CAN controller Port 5 External interrupt (8 ch) Port 8 Stepping motor Controller 0/1/2/3 UART0/1 Prescaler 0/1 Port 0 PPG0/1/2 P10/PPG2 P11/TOT0/WOT P12/TIN0/IN3 P13/IN2 P14/IN1 P15/IN0 F2MC-16LX BUS X0, X1 X0A, X1A RST Port 7 A/D converter (8 ch) P67 - P60/ AN7 - AN0 AVCC/AVSS AVRH Port 9 P91 - P90/ SEG23 - SEG22 Port 4 P47 - P40/ SEG21 - SEG14 Port 3 P37 - P36/ SEG13 - SEG12 Real-time Clock timer ICU0/1/2/3 Free-run timer Evaluation device (MB90V420G) No built-in ROM Built-in RAM is 6 KB. 16 P77/PWM2M1 P76/PWM2P1 P75/PWM1M1 P74/PWM1P1 P73/PWM2M0 P72/PWM2P0 P71/PWM1M0 P70/PWM1P0 Port 6 Port 1 Reload timer 0/1 P87/PWM2M3 P86/PWM2P3 P85/PWM1M3 P84/PWM1P3 P83/PWM2M2 P82/PWM2P2 P81/PWM1M2 P80/PWM1P2 LCD controller/ driver SEG11 - SEG0 COM3 - COM0 V3 - V0 MB90420G/5G (A) Series MEMORY MAP Single chip mode (with ROM mirror function) 000000H Peripheral area 0000C0H 000100H Register RAM area Address #2 003900H Peripheral area 004000H 010000H ROM area (FF bank image) FF0000H Address #1 ROM area FFFFFFH : Internal access memory : Access prohibited Parts No. Address #1 Address #2 MB90423G (A) FE0000H 001900H MB90427G (A) FF0000H 001100H MB90428G (A) FE0000H 001900H MB90F423G (A) FE0000H 001900H MB90F428G (A) FE0000H 001900H MB90V420G FE0000H * 001900H * : MB90V420G has no built-in ROM. On the tool side this area may be considered a ROM decoder. 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. 17 MB90420G/5G (A) Series I/O MAP * Other than CAN Interface Address Register name Symbol Read/write Peripheral function Initial value 00H Port 0 data register PDR0 R/W Port 0 XXXXXXXX 01H Port 1 data register PDR1 R/W Port 1 -

Watchdog Timer/Time Base Timer/Clock Timer The watchdog timer, timer base timer, and clock 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 * Clock 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 clock 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) Clock timer function The clock 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 clock timer uses the sub clock regardless of the setting of the MCS bit or SCS bit in the CKSCR register. 36 MB90420G/5G (A) Series * Block Diagram Main base oscillator divided by 2 TBTC TBC1 Selector TBC0 TBR TBIE AND Q 211 213 216 218 TBTRES Clock input Time base timer 211 213 216 218 S R TBOF Time base interrupt WDTC WT1 Selector 2-bit counter OF CLR WT0 Watchdog reset generator circuit CLR WTE To WDGRST internal reset generator circuit F2MC-16LX bus WTC WDCS SCE AND Q SGW Power-on reset, sub-clock stop S R WTC2 Selector WTC0 WTR WTIE WTOF Clock interrupt AND Q S R 28 29 210 211 212 213 214 216 WTRES 210 213 214 216 Clock timer Clock input Sub base oscillator divided by 4 WDTC PONR From power-on generator WRST ERST RST pin SRST From RST bit in STBYC register 37 MB90420G/5G (A) Series 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.

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) One-shot mode Reload mode One-shot mode 16-bit reload timer operation Soft trigger operation External trigger operation External gate input operation Soft trigger operation (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.

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.

Real Time Clock Timer The real time clock timer is composed of a real time clock timer control register, sub second data register, second/ minute/hour data registers, 1/2 clock divider, 21-bit prescaler and second/minute/hour counters. Because the MCU oscillation frequency operates on a given real time clock timer operation, a 4 MHz frequency is assumed.

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.

Delayed Interrupt Generator Module The delayed interrupt generator module is a module that generates interrupts for task switching. This module makes it possible to use software to generate/cancel interrupt requests to the F2MC-16LX CPU. * Block diagram F2MC-16LX bus Delayed interrupt source generate/delete decoder Source latch 44 MB90420G/5G (A) Series 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 Interrupt sources DTP function 8 pins (P50/INT0 to P53/INT3, P00/INT4 to P03 INT7) Request level setting register (ELVR) sets the detection level, or selected edge for each pin "H" level/ "L" level/ rising edge/falling edge input "H" level/ "L" level input Interrupt numbers #16 (10H) , #18 (12H) , #20 (14H) , #22 (16H) , #24 (18H) , #26 (1AH) Interrupt control DTP/interrupt enable register (ENIR) permits/prohibits interrupt request output Interrupt flags DTP/interrupt enable register (EIRR) stores interrupt sources Process selection When EI2OS prohibited (ICR : ISE = 0) When EI2OS is enabled (ICR : ISE = 1) Processing Branch to external interrupt processing routine EI2OS performs automatic data transfer, then after a specified number of cycles, branches to an interrupt routine ICR : Interrupt control register 45 MB90420G/5G (A) Series (2) Block diagram Request level setting register (ELVR) LB7 LA7 LB6 LA6 LB5 LA5 LB4 LA4 LB3 LA3 LB2 LA2 LB1 LA1 LB0 LA0 Pin Selector Selector Internal data bus P03/INT7 Pin P50/INT0 Pin Selector Selector P02/INT6 Pin P51/INT1 Selector Pin Selector P01/INT5 Pin P52/INT2 Selector Pin Selector Pin P00/INT4 P53/INT3 ER7 ER6 ER5 ER4 ER3 ER2 ER1 ER0 Interrupt request number #16 (10H) #18 (12H) #20 (14H) #22 (16H) #24 (18H) #26 (1AH) EN7 46 EN6 EN5 EN4 EN3 EN2 EN1 EN0 MB90420G/5G (A) Series 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) .

Functions include normal bi-directional functions, as well as master/slave type communication functions (multi-processor mode : master side only supported) .

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 Number of oscillation clock cycles Approx. 262 ms * 220 cycles * : This value assumes an oscillation clock speed 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 clock mode 6.

Stepping Motor Controller The stepping motor controller is composed of two PWM pulse generators, four motor drivers and selector logic circuits. The four motor drivers have a high output drive capacity and can be directly connected to the four ends of two motor coils. They are designed to operate together with the PWM pulse generators and selector logic circuits to control motor rotation. A synchronization mechanism assures synchronization of the two PWM pulse generators. * Block diagram Machine clock OE1 Prescaler CK PWM1Pn PWM1 pulse generator EN P1 Output enable Selector PWM PWM1Mn P0 PWM1 compare register PWM1 selector register OE2 Output enable CK SC PWM2Pn PWM2 pulse generator CE EN Selector PWM PWM2Mn Load PWM2 compare register BS PWM2 select register n:0~3 57 MB90420G/5G (A) Series 15.

Address Match Detect Function If the address setting is the same as the ROM correction address register, an INT9 instruction is executed. The ROM correction 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.

Lower-case letters: Replaced when described in assembler. Numbers after lower-case letters: Indicate the bit width within the instruction code. Indicates the number of bytes. Indicates the number of cycles. m : When branching n : When not branching See Table 4 for details about meanings of other letters in items. Indicates the number of accesses to the register during execution of the instruction. It is used calculate a correction value for intermittent operation of CPU. Indicates the correction value for calculating the number of actual cycles during execution of the instruction. (Table 5) The number of actual cycles during execution of the instruction is the correction value summed with the value in the "~" column. Indicates the operation of instruction. Indicates special operations involving the upper 8 bits of the lower 16 bits of the accumulator. Z : Transfers "0". X : Extends with a sign before transferring. - : Transfers nothing. Indicates special operations involving the upper 16 bits in the accumulator. * : Transfers from AL to AH. - : No transfer. Z : Transfers 00H to AH. X : Transfers 00H or FFH to AH by signing and extending AL. Indicates the status of each of the following flags: I (interrupt enable), S (stack), T (sticky bit), N (negative), Z (zero), V (overflow), and C (carry). * : Changes due to execution of instruction. - : No change. S : Set by execution of instruction. R : Reset by execution of instruction. Indicates whether the instruction is a read-modify-write instruction. (a single instruction that reads data from memory, etc., processes the data, and then writes the result to memory.) * : Instruction is a read-modify-write instruction. - : Instruction is not a read-modify-write instruction. Note: A read-modify-write instruction cannot be used on addresses that have different meanings depending on whether they are read or written. * Number of execution cycles The number of cycles required for instruction execution is acquired by adding the number of cycles for each instruction, a corrective value depending on the condition, and the number of cycles required for program fetch. Whenever the instruction being executed exceeds the two-byte (word) boundary, a program on an internal ROM connected to a 16-bit bus is fetched. If data access is interfered with, therefore, the number of execution cycles is increased. For each byte of the instruction being executed, a program on a memory connected to an 8-bit external data bus is fetched. If data access in interfered with, therefore, the number of execution cycles is increased. When a general-purpose register, an internal ROM, an internal RAM, an internal I/O device, or an external bus is accessed during intermittent CPU operation, the CPU clock is suspended by the number of cycles specified by the CG1/0 bit of the low-power consumption mode control register. When determining the number of cycles required for instruction execution during intermittent CPU operation, therefore, add the value of the number of times access is done x the number of cycles suspended as the corrective value to the number of ordinary execution cycles. 78 MB90420G/5G (A) Series Table 2 Explanation of Symbols in Tables of Instructions Symbol A Meaning 32-bit accumulator The bit length varies according to the instruction.
