1.1 Overview  
1.1 Overview  
The M3A-HS25 is the CPU board designed for users to evaluate the functionality and performance of the SH7125  
group of Renesas Technology original microcomputers, as well as develop and evaluate the application software for  
this group of microcomputers. The SH7125's internal peripheral circuit function pins are connected to the extension  
connector of the M3A-HS25, allowing users to evaluate the timing relationship with peripheral devices using  
measurement instruments or develop extension boards tailored to suit development purposes. Furthermore, the  
E10A-USB or the on-chip emulator made by Renesas Technology can also be connected to the M3A-HS25.

2.2 CPU  
The M3A-HS25 contains the 32-bit RISC microcomputer SH7125 that operates with a maximum 50MHz of CPU  
clock frequency. 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). Switch the setting of the JP3 and  
JP4 according to the connector used.  
Figure2.3.1 shows the block diagram of serial port interface in the M3A-HS25.

2.5 Clock Module  
The clock module in the M3A-HS25 consists of the following two blocks:  
• Output from a oscillator connected to EXTAL of the SH7125  
• Ceramic resonator connected to EXTAL and XTAL  
The M3A-HS25 has a 12.5MHz oscillator connected to it as standard specification.  
Figure2.5.1 shows the block diagram of clock module.

2.8 E10A-USB Interface  
The M3A-HS25 has a 14-pin H-UDI connector included in it for connection to the E10A-USB.  
TMS pins and TRST pins of SH7125 are multiplexed with transmit/receive pins of SCI channel 1. When H-UDI  
connector is used, make sure that the settings of JP3 and JP4 are set to 1-2 side.  
In addition, H-UDI pin of SH7125 is connected to the extension connector, do not use the applicable pins of the  
extension connector when debugging with the H-UDI connector.
