M16C/62

The Mitsubishi M16C/62 series of microcontrollers is a 16-bit family of MCUs, based on Mitsubishi's popular M16C CPU core. These parts provide high memory efficiency, power-saving ability, low noise emission, and improved noise immunity. The flash versions of the device contain flash memory that can be rewritten with a single voltage.

The M16C/62 flash can be programmed using one of three methods: Parallel I/O Mode, Standard Serial I/O Mode, and CPU Rewrite Mode. Standard Serial I/O Mode can be further divided into a synchronous mode (Standard Serial I/O Mode 1) and an asynchronous mode (Standard Serial I/O Mode 2). The flash memory is divided into two major blocks, a user program area and a boot ROM area. The user program area is for the normal application program and data. Any program in the boot ROM area is accessed only when a special hardware reset sequence is initiated. This boot ROM area has a control program stored in it when shipped from the factory. The program allows asynchronous or synchronous serial programming of the user area of the flash. Changes to the boot area of the flash can only be made using Parallel I/O Mode.

Mitsubishi M16C/62 provides a Windows based program, FlashStart, to serially download code (in S-record format) to  16C/62 MCUs. The website for downloading the program is given in the Reference section.
