Description
The M30240 group is a 16-bit microcomputer based on the M16C family core technology. They are single-chip USB peripheral microcontrollers based on the Universal Serial Bus (USB) Version 1.1 specification. They are packaged in an 80-pin, molded plastic QFP. These single-chip microcontrollers operate using sophisticated instructions featuring a high level of instruction efficiency, making them 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.
