The SH7125 includes 128-Kbyte flash memory, and 8-Kbyte SRAM, making it useful in a wide range of applications from data processing to equipment control. The M3A-HS25 can be operated with a maximum 50MHz of CPU clock frequency using a 12.5MHz input clock. Figure2.2.1 shows the block diagram of SH7125 in the M3A-HS25.
2.3 Serial Port Interface The SH7125 included in the M3A-HS25 contains a UART module. In the M3A-HS25, the pins of SCI channel 0 or SCI channel 1 can be connected to J2 (Serial Port connector). The pins of SCI channel 1 (RXD1(PA3) pin and TXD 1 (PA4)pin) are also connected to H-UDI connector, and extension connector (J5, J7).
2.4 I/O Ports In the M3A-HS25, all of the SH7125's I/O ports are connected to the extension connector. Some I/O ports are connected to DIP switches and LEDs of the M3A-HS25 board. Users are free to use these ports. Figure2.4.1 shows the block diagram of DIP switch and LEDs in the M3A-H25.
