The M30245 group is a 16-bit microcomputer based on the M16C family core technology that uses a high performance silicon gate CMOS process with an M16C/62 Series CPU core. It comes packaged in a 100-pin molded plastic LQFP. They are single-chip USB peripheral microcontrollers that operate at Full Speed (12 Mbps) and are compliant with the Universal Serial Bus (USB) Version 2.0 specification. They also include many built-in peripherals including: A/D converter, Timers, UARTs, Serial Sound Interface, I2C, DMAC, CRC and more. These microcontrollers operate using sophisticated instructions featuring a high level of instruction efficiency, making them capable of executing instructions at high speed.
