The MB90435 series is a 16-bit proprietary microcontroller with FLASH ROM specially designed for industrial applications. The instruction set by F2MC-16LX CPU core inherits an AT architecture of the F2MC family with additional instruction sets for high-level languages, extended addressing mode, enhanced multiplication/division instructions, and enhanced bit manipulation instructions. The microcontroller has a 32-bit accumulator for processing long word data. The MB90435 series has peripheral resources of 8/10-bit A/D converters, UART (SCI), extended I/O serial interfaces, 8/16-bit timer, I/O timer (input capture (ICU), output compare (OCU)).
