2.2 CPU
The M3A-HS37 is provided with the SH7137, the 32-bit RISC MCU operates with a maximum frequency of 80 MHz.
The SH7137 MCU is provided with a 256-KB flash memory, and a 16-KB RAM, which covers a wide range of applications
from data processing to equipment control.
The M3A-HS37 can be operated with a maximum CPU frequency of 80 MHz (external bus 40 MHz at maximum) using a 10.0
MHz of the input clock.
Figure 2.2.1 shows the SH7137 block diagram on the M3A-HS37.
