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.
