Description

The Electronic Component Model 437L178 is part of the MB90435 series with FLASH ROM, specially designed for industrial applications. This model features the F2MC-16LX CPU core with an AT architecture inherited from the F2MC* family. It includes 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 also offers peripheral resources such as 8/10-bit A/D converters, UART (SCI), extended I/O serial interfaces, 8/16-bit timer, and I/O timer (input capture (ICU), output compare (OCU)).
