These are housed in 80-pin plastic molded QFP. These microcomputers have a CPU and a bus interface unit. The CPU is a 16-bit parallel processor that can also be switched to perform 8-bit parallel processing, and the bus interface unit enhances the memory access efficiency to execute instructions fast. In addition to the 7700 Family basic instructions, the M37753FFCFP and the M37753FFCHP have 6 special instructions which contain instructions for signed multiplication/division; these added instructions improve the servo arithmetic performance to control hard disk drives and so on. These microcomputers also include the flash memory, RAM, multiple-function timers, motor control function, serial I/O, A-D converter, D-A converter, and so on. The internal flash memory can be programed and erased by using a PROM programmer or by control of the central processing unit (CPU). Therefore, these microcomputers can change the program easily even after they are mounted on the board.

This pin controls the processor mode. Connect to VSS for single-chip mode or memory expansion mode. Connect to VCC for microprocessor mode. This is reset input pin. The microcomputer is reset when supplying "L" level to this pin. These are I/O pins of internal clock generating circuit. Connect a ceramic or quartzcrystal resonator between XIN and XOUT. When an external clock is used, the clock source should be connected to the XIN pin and the XOUT pin should be left open. Data or instruction read, data write are performed when output from this pin is "L". This pin determines whether the external data bus is 8-bit width or 16-bit width for memory expansion mode or microprocessor mode. The width is 16 bits when "L" signal inputs and 8 bits when "H" signal inputs. Power supply for the A-D converter and the D-A converter. Connect AVCC to VCC and AVSS to VSS externally. This is reference voltage input pin for the A-D converter and the D-A converter. In single-chip mode, port P0 is an 8-bit I/O port. This port has an I/O direction register and each pin can be programmed for input or output. These ports are in the input mode when reset. Address (A0-A7) is output in memory expansion mode or microprocessor mode. In single-chip mode, these pins have the same functions as port P0. When the BYTE pin is set to "L" in memory expansion mode or microprocessor mode and external data bus is 16-bit width, high-order data (D8-D15) is input or output if E output is "L" and an address (A8-A15) is output if E output is "H". When the BYTE pin is set to "H" and an external data bus is 8-bit width, only address (A8-A15) is output. In single-chip mode, these pins have the same functions as port P0. In memory expansion mode or microprocessor mode, low-order data (D0-D7) is input or output when E output is "L" and an address (A16-A23) is output when E output is "H". In single-chip mode, these pins have the same functions as port P0. In memory expansion mode or microprocessor mode, R/W, BHE , ALE, and HLDA signals are output. In single-chip mode, these pins have the same functions as port P0. In memory expansion mode or microprocessor mode, P40, P41, and P42 become HOLD and RDY input pins, and clock 1 output pin respectively. Functions of other pins are the same as in single-chip mode. In memory expansion mode, P42 can be programmed as I/O port. In addition to having the same functions as port P0 in single-chip mode, these pins also function as I/O pins for timer A0, timer A1, timer A2, timer A3, output pins for motor drive waveform, and input pins for key input interrupt. In addition to having the same functions as port P0 in single-chip mode, these pins also function as the I/O pin for timer A4, input pins for external interrupt input INT0, INT1, and INT2, and input pins for timer B0, timer B1, and timer B2, and output pin for motor drive wave form. In addition to having the same functions as port P0 in single-chip mode, these pins also function as input pins for A-D converter. In addition to having the same functions as port P0 in single-chip mode, these pins also function as I/O pins for UART0, UART1, output pins for D-A converter, and input pins for INT3, INT4. Analog supply input Reference voltage input I/O port P0 Input I/O P10-P17 I/O port P1 I/O P20-P27 I/O port P2 I/O P30-P33 I/O port P3 I/O P40-P47 I/O port P4 I/O P50-P57 I/O port P5 I/O P60-P67 I/O port P6 I/O P70-P77 P80-P87 I/O port P7 I/O port P8 I/O I/O Note: It is impossible to change the input level of the BYTE pin in each bus cycle. In other words, bus width cannot be switched dynamically. Fix the input level of the BYTE pin to "H" or "L" according to the bus width used. 6 PR e. n. atio chang cific o spe bject t l fina su ot a its are is n m This etric li m ice: Not e para Som MI ELI Y NAR MITSUBISHI MICROCOMPUTERS M37753FFCFP M37753FFCHP SHINGLE-CHIP 16-BIT CMOS MICROCOMPUTER FLASH MEMORY VERSION PIN DESCRIPTION (FLASH MEMORY PARALLEL I/O MODE) Pin VCC, VSS CNVSS BYTE _____ RESET XIN XOUT _ E AVCC, AVSS VREF P00-P07 P10-P17 P20-P27 P30-P33 P40-P47 P50-P57 P60-P67 P70-P77 P80-P87 Name Power supply VPP input Bus width select input Reset input Clock input Clock output Enable output Analog supply input Reference voltage input Address input (A0-A7) Address input (A8-A15) Data I/O (D0-D7) Input port P3 Input port P4 Control signal input Input port P6 Input port P7 Input port P8 Input /Output -- Input Input Input Input Output Output -- Input Input Input I/O Input Input Input Input Input Input Functions Supply 5 V 10 % to VCC and 0 V to VSS.

The user can use this mode to perform read, program, and erase operations for the internal flash memory. The M37753FFCFP and the M37753FFCHP have three modes the user can choose: the parallel input/output and serial input/output mode, where the flash memory is handled by using the external programmer, and the CPU reprogramming mode, where the flash memory is handled by the central processing unit (CPU). The following explains these modes. Functional outline (Parallel input/output mode) In the parallel input/output mode, the M37753FFCFP and the M37753FFCHP allow the user to choose an operation mode between the read-only mode and the read/write mode (software command control mode) depending on the voltage applied to the VPP pin. When VPP = VPPL, the read-only mode is selected, and the user can choose one of three states (e.g., read, output disable, or standby) de___ ___ ___ pending on inputs to the CE, OE, and WE pins. When VPP = VPPH, the read/write mode is selected, and the user can choose one of four states (e.g.,__ __ read, output ___ disable, standby, or write) depending on inputs to the CE, OE, and WE pins. Table 2 shows assignment states of control input and each state. Flash memory mode 1 (parallel I/O mode) The parallel I/O mode can be selected by connecting wires as shown in Figures 6, 7 and supplying power to the VCC and VPP pins. In this mode, the M37753FFCFP and the M37753FFCHP operate as an equivalent of MITSUBISHI's CMOS flash memory M5M28F101. However, because the M37753FFCFP and the M37753FFCHP's internal memory has a capacity of 120 Kbytes, programming is available for addresses 0100016 to 1EFFF16, and make sure that the data in addresses 0000016 to 00FFF16 and addresses 1F00016 to 1FFFF16 are FF16. Note also that the M37753FFCFP and the M37753FFCHP do not contain a facility to read out a device identification code by applying a high voltage to address input (A9). Be careful not to erratically set program conditions when using a general-purpose PROM programmer. Table 1 shows the pin assignments when operating in the parallel input/output mode. Read __ __ The microcomputer enters the read state by driving the CE, and OE ___ pins low and the WE pin high; and the contents of memory corresponding to the address to be input to address input pins (A0-A16). are output to the data input/output pins (D0-D7). Output disable __ The microcomputer enters the output disable state by driving the CE ___ __ pin low and the WE and OE pins high; and the data input/output pins enter the floating state. Standby __ The microcomputer enters the standby state by driving the CE pin high. The M37753FFCFP and the M37753FFCHP are placed in a power-down state consuming only a minimal supply current. At this time, the data input/output pins enter the floating state. Table 1.

In this state, software commands can be input from the data input/output pins, and the user can choose program or erase operation depending on the contents of this software command. Table 2.

When control signals are input in the second cycle at the timing shown in Figure 11, the M37753FFCFP and the M37753FFCHP output the contents of the specified address to the external. Note: If any memory location where the contents have not been erased is found in the erase verify operation, execute the operation of "erase erase verify" over again. In this case, however, the user does not need to write data 0016 to memory locations before erasing.

This is called the serial I/ O (input/output) mode. This mode can be selected by driving the __ SDA (serial data input/output), SCLK (serial clock input ), and OE pins high after connecting wires as shown in Figures 13, 14 and powering on the VCC pin and then applying VPPH to the VPP pin. In the serial I/O mode, the user can use seven types of software commands: bank (0, 1) select, read, program, program verify, auto erase, and error check. Serial input/output is accomplished synchronously with the clock, beginning from the LSB (LSB first).

The input data is read from the SDA pin into the internal circuit synchronously with the rising edge of the serial clock pulse; the output data is output from the SDA pin synchronously with the falling edge of the serial clock pulse.

In the first transfer, the user inputs the command code. This is followed by address input and data input/output according to the contents of the command.

Third ---------- ---------- Read address H (Input) Program address H (Input) ---------- ---------- ---------- Fourth ---------- ---------- Read data (Output) Program data (Input) ---------- ---------- ---------- Bank select command This is the command which specifies the bank of the flash memory, which is to be read/programmed, before executing the read command or the program command (and the program verify command). There are the bank 0 select command (command code "E016"), which selects bank 0 (addresses 0000016 to 0FFFF16), and the bank 1 select command (command code "E116"), which selects bank 1 (addresses 1000016 to 1FFFF16). When any bank select command is input once, specified bank is valid until the next bank select command is input. Accordingly, when the read command or the program command (and the program verify command) is executed to plural bytes in the same bank, if any bank select command is input first, it is unnecessary to input the bank select command again for the following bytes. When selecting the serial I/O mode (before bank command input), bank 0 is selected. Note: Bank select command does not affect the auto erase command, that is to say, when executing the auto erase command, all flash memory is erased collectively regardless of specified bank. And in the same way, the bank select command does not affect the error check command. tCH SCLK SCLK tCH SDA 00000111 Command code input (E016) SDA 10000111 Command code input (E116) OE "H" OE "H" BUSY "L" BUSY "L" Bank 0 select command Bank 1 select command Fig. 15 Timings during bank select 26 PR e. n. atio chang cific o spe bject t l fina su ot a its are is n m This etric li m ice: Not e para Som MI ELI Y NAR MITSUBISHI MICROCOMPUTERS M37753FFCFP M37753FFCHP SHINGLE-CHIP 16-BIT CMOS MICROCOMPUTER FLASH MEMORY VERSION Read command Input command code 0016 in the first transfer.

If the E0 of the 8-bit error information is 1, it indicates that a command error has occurred. A command error means that some invalid commands other than commands shown in Table 4 has been input. When a command error occurs, the serial communication circuit sets the corresponding flag and stops functioning to avoid an erroneous programming or erase. When being placed in this state, the serial communication circuit does not accept the subsequent serial clock and data (even including an error check command). Therefore, if the user wants to execute an error check command, temporarily drop the VPP pin input to the VPPL level to terminate the serial input/output mode. Then, place the M37753FFCFP and the M37753FFCHP into the serial I/O mode back again. The serial communication circuit is reset by this operation and is ready to accept commands. The error flag alone is not cleared by this operation, so the user can examine the serial communication circuit's error conditions before reset. This examination is done by the first execution of an error check command after the reset. The error flag is cleared when the user has executed the error check command. Because the error flag is undefined immediately after power-on, always be sure to execute the error check command. tCH SCLK E0 SDA 00000001 Command code input (8016) "H" ???????

Remaining 8 Kbytes of the flash memory (addresses 00F00016 to 010FFF16) cannot be reprogrammed, but can be read. (It is possible to reprogram this remaining 8 Kbytes in the parallel I/O mode and the serial I/O mode). This area of 8 Kbytes can be used as an area where the control program of CPU reprogramming mode is stored. In CPU reprogramming mode, the flash memory is handled by writing and reading to/from the flash memory control register (see Figure 21) and the flash command register (see Figure 22). The CNVSS pin is used as the VPP power supply pin in CPU reprogramming mode. It is necessary to apply the power-supply voltage of VPPH from the external to this pin. Functional outline (Parallel input/output mode) Figure 21 shows the flash memory control register bit configuration. Figure 22 shows the flash command register bit configuration. Bit 0 of the flash memory control register is the CPU reprogramming mode select bit. When this bit is set to "1" and VPPH is applied to the CNVss/VPP pin, the CPU reprogramming mode is selected. Whether the CPU reprogramming mode is realized or not is judged by reading the CPU reprogramming mode monitor flag (bit 3 of the flash memory control register). Bit 1 is a busy flag which becomes "1" during auto erase, erase, and program execution. Whether these operations have been completed or not is judged by checking this flag after each command of auto erase, erase, and the program is executed. Bits 4, 5 of the flash memory control register are the erase/program area select bits. These bits specify an area where auto erase, erase, and program is operated. When the auto erase and the erase commands are executed after an area is specified by these bits, only the specified area is erased. Only for the specified area, programming is enabled; for the other areas, programming is disabled. Figure 23 shows the processor mode register 0 bit configuration in the CPU reprogramming mode. Set bit 1 to "0" (single-chip or memory expansion mode) in the CPU reprogramming mode. Set bit 2 (internal memory access bus cycle select bit) to "0."

Set the CPU reprogramming mode select bit to "0." Each software command is explained as follows. Read command When "0016" is written to the flash command register, the M37753FFCFP and the M37753FFCHP enter the read mode. The contents of the corresponding address can be read by reading the flash memory (For instance, with the LDA instruction etc.) under this condition. The read mode is maintained until another command code is written to the flash command register. Accordingly, after setting the read mode once, the contents of the flash memory can continuously be read.

Subsequently to this, if the instruction (for instance, STA or LDM instruction) for writing byte data in the address to be programmed is executed, the control circuit of the flash memory executes the program. The auto erase/erase/program busy flag of the flash memory control register is set to "1" when the program starts, and becomes "0" when the program is completed. Accordingly, after the write instruction is executed, CPU can recognize the completion of the program by polling this bit. The programmed area must be specified beforehand by the erase/ program area select bits. During programming, watchdog timer stops with "FFF16" set. Note: A programming operation is not completed by executing the program command once. Always be sure to execute a program verify command after executing the program command. When the failure is found in this verification, the user must repeatedly execute the program command until the pass. Refer to Figure 24 for the flow chart of the programming. Erase command When writing "2016" twice continuously to the flash command register, the flash memory control circuit performs erase to the area specified beforehand by the erase/program area select bits. Auto erase/erase/program busy flag of the flash memory control register becomes "1" when erase begins, and it becomes "0" when erase completes. Accordingly, CPU can recognize the completion of erase by polling this bit. Data "0016" must be written to all areas to be erased by the program and the program verify commands before the erase command is executed. During programming, watchdog timer stops with "FFF16" set. Note: The erasing operation is not completed by executing the erase command once. Always be sure to execute an erase verify command after executing the erase command. When the failure is found in this verification, the user must repeatedly execute the erase command until the pass. Refer to Figure 24 for the erasing flowchart. Erase verify command When "A016" is written to the flash command register, the M37753FFCFP and the M37753FFCHP enter the erase verify mode. Subsequently to this, if the instruction (for instance, LDA instruction) for reading byte data from the address to be verified, the contents of the address is read. CPU must erase and verify to all erased areas in a unit of address. If the address of which data is not "FF16" (i.e., data is not erased) is found, it is necessary to discontinue erasure verification there, and execute the operation of "erase erase verify" again. Note: By executing the operation of "erase erase verify" again when the memory not erased is found. It is unnecessary to write data "0016" before erasing in this case. Program verify command When "C016" is written to the flash command register, the M37753FFCFP and the M37753FFCHP enter the program verify mode. Subsequently to this, if the instruction (for instance, LDA instruction) for reading byte data from the address to be verified (i.e., previously programmed address), the contents which has been written to the address actually is read. CPU compares this read data with data which has been written by the previous program command. In consequence of the comparison, if not agreeing, the operation of "program program verify" must be executed again. 33 PR e. n. atio chang cific o spe bject t l fina su ot a its are is n m This etric li m ice: Not e para Som MI ELI Y NAR MITSUBISHI MICROCOMPUTERS M37753FFCFP M37753FFCHP SHINGLE-CHIP 16-BIT CMOS MICROCOMPUTER FLASH MEMORY VERSION Program START Erase START ADRS = first location YES ALL BYTES = 0016 ?

(1) Data "0016" is written to the area to be erased in the flash memory. (2) The erasure is executed. (3) The contents of the erased flash memory is erase-verified one by one. When the address which is not erased is found, verification is interrupted, and after the erase command is executed again, erase-verification is operated again. (4) When the erasure of all areas specified to be erased, is confirmed by erase-verify-operation, the auto erase command is ended. The auto erase/erase/program busy flag of the flash memory control register becomes "1" when auto erase starts, and becomes "0" when auto erase completes. Accordingly, CPU can recognize the completion of auto erase by polling this bit. During auto erase, watchdog timer stops with "FF16" set. Note: When the flash memory is erased by using the auto erase command, it is unnecessary to execute the erase and erase verify commands. Figure 25 shows the flowchart when auto erase is executed. Reset command The reset command is a command to discontinue the program, erase, or the auto erase command on the way. When "FF16" is written to the command register two times continuously after "4016," "2016," or "3016" is written to the flash command register, the program, erase, or auto erase command becomes invalid (reset), and the M37753FFCFP and the M37753FFCHP enters the reset mode.
