Functional Overview 2 2.2 CPU 2.2 CPU The M3A-HS85 contains the 32-bit RISC microcomputer SH7285 that operates with a maximum 100MHz of CPU clock frequency. The SH7285 includes 768-Kbyte flash memory, and 32-Kbyte RAM, making it useful in a wide range of applications from data processing to equipment control. The M3A-HS85 can be operated with a maximum 100MHz of CPU clock frequency (external bus maximum 50 MHz) using a 12.5 MHz input clock. Figure 2.2.1 shows the SH7285 block diagram in the M3A-HS85.
Functional Overview 2 2.3 Memory 2.3 Memory 2.3.1 SH7285 On-Chip Memory The SH7285 includes a 768-Kbytes flash memory and 32-Kbytes RAM. 2.3.2 SRAM Two Mbytes of SRAM can be mounted on the M3A-HS85 (Not mounted). In the M3A-HS85 specification, 3.3V power is supplied to SRAM so that SH7285 should be used in 3.3V when SRAM is mounted (CPU power supply switch jumper (JP1) should be set to “2-3”). SRAM is controlled by the bus state controller built into SH7285.
Functional Overview 2 2.3.3 SDRAM 2.3.3 SDRAM The M3A-HS85 can mount 16Mbytes of SDRAM (Not mounted). In the M3A-HS85 specification, 3.3V power is supplied to SDRAM so that SH7285 should be used in 3.3V when SDRAM is mounted (CPU power supply switch jumper (JP1) should be set to “2-3”). The SDRAM is controlled by the bus state controller built into SH7285. Table 2.3.2 lists the SDRAM specifications. Figure 2.3.2 shows the block diagram for the connection between SH7285 and SDRAM. Table 2.3.
Functional Overview 2 2.3.4 EEPROM 2.3.4 EEPROM The M3A-HS85 can mount the 128k-bits of EEPROM (Not mounted). The EEPROM is controlled by the I2C bus interface included in SH7285. Table 2.3.3 lists the specification outline of EEPROM. Figure 2.3.3 shows the connection circuit block diagram of SH7285 and EEPROM.

Functional Overview 2 2.6 Power Supply Module 2.6 Power Supply Module In M3A-HS85, 5V power is input to the board and 3.3V is generated by using a regulator. The regulator used is output voltage variable type and given voltage value can be generated by changing the resistance value. 5V power can be supplied from DC stabilized power supply (via power supply connector (J4)) and AC adapter (via DC power supply jack (J7)). SH7285 system power supply (VCC) can be switched to 3.
Functional Overview 2 2.7 USB Interface 2.7 USB Interface The M3A-HS85 contains a USB connector (Standard-B receptacle). When a cable is connected to USB host/hub in the state that this CPU board is not turned on, the voltage is impressed from USB host/hub to VBUS. Thus, the CPU board should be turned on before USB cable is connected. When you want to delay a notification of connection to USB host/hub (the cases such as in the processing of high priority or initialization), it can be controlled by PB10.
Functional Overview 2 2.8 Clock Module 2.8 Clock Module The clock module in the M3A-HS85 consists of the following two blocks: • • Output from a oscillator connected to EXTAL of the SH7285 Ceramic resonator connected to EXTAL and XTAL The M3A-HS85 has a 12.5MHz ceramic oscillator connected to it as standard specification. (The oscillator is mounted via 8-pin IC socket.) When the ceramic resonator is used, R7 should be removed. Figure 2.8.1 shows the block diagram of clock module.
Functional Overview 2 2.9 Reset Module 2.9 Reset Module This circuit controls the reset signal of SH7285 mounted on the M3A-HS85. Figure 2.9.1 shows the block diagram of reset module in the M3A-HS85. Figure 2.9.1 Block Diagram of Reset Module 2.10 Interrupt Switches In the M3A-HS85, the push switches are connected with the pins NMI and IRQ1 of SH7285. Figure 2.10.1 shows the block diagram of interrupt switch. Figure 2.10.1 Block Diagram of Interrupt Switch Rev.1.04 2008.7.
Functional Overview 2 2.11 E10A-USB Interface 2.11 E10A-USB Interface The M3A-HS85 has the H-UDI connectors (J1 and J2) to connect with E10A-USB. ____________________ ________________ ASEBRKAK/ASEBRK/FWE pin of SH7285 is connected to DIP switch for system setting (SW4-1). When the M3A-HS85 is connected to E10A-USB, SW4-1 should be set to “OFF” after FWE switch jumper (JP6) is set to “1-2”. When it is connected to E10A-USB in the state that SW4-1 is set to “ON”, it cannot be normally debugged. Figure 2.
