2.2.1 SH7206
The M3A-HS60 contains SH7206, the 32-bit RISC microcomputer, which operates with a maximum 200MHz of CPU
clock frequency. The SH7206 includes 128-Kbyte RAM, 8-Kbyte instruction cache and 8-Kbyte data cache, and it can
deal with a wide range of applications from data processing to equipment control.
The M3A-HS60 can be operated with a maximum 200MHz of CPU clock frequency (external bus 66.67MHz, max.)
using a 16.67MHz input clock.
Figure2.2.1 shows the block diagram of SH7206 in the M3A-HS60.
