Features
1.0 Description
The M3024 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 microcomputers
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.
