We can Decode Chip Mitsubishi M30620ECFP, please view the MCU IC features for your reference:
The M16C/62 group of single-chip microcomputers are built using the high-performance silicon gate CMOS process using a M16C/60 Series CPU core and are packaged in a 100-pin plastic molded QFP. These single-chip microcomputers operate using sophisticated instructions featuring a high level of instruction efficiency.
With 1M bytes of address space, they are capable of executing instructions at high speed. They also feature a built-in multiplier and DMAC, making them ideal for controlling office, communications, industrial equipment, and other high-speed processing applications.
The M16C/62 group includes a wide range of products with different internal memory types and sizes and various package types.
