1.1 Overview
1.1 Overview
The M3A-HS25 is the CPU board designed for users to evaluate the functionalit y and performance of the SH7125
group of Renesas Technology original microcomputers, as well as develop an d 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.
