1.1 Overview
The M3A-HS85 is the CPU board designed for users to evaluate the functionality and performance of the SH7285
group of Renesas Technology original microcomputer, as well as develop and evaluate the application software for
this group of microcomputers. The Sh7285's data bus, address bus and various internal peripheral circuit function
pins are connected to the extension connector of the M3A-HS85, 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-HS85.
