This document describes the FUJITSU MB90420G/425G series, a 16-bit original microcontroller CMOS F2MC-16LX designed for vehicle meter control applications. The microcontroller features 16-bit input capture, 16-bit reload timer, watch timer, and 16-bit pulse width modulation.
The Fujitsu MB90420G/425G Series is a 16-bit general purpose high-capacity microcontroller designed for vehicle meter control applications. The instruction set retains the same AT architecture as the original F2MC-8L and F*MC-16L series, with refinements including high-level language instructions, expanded addressing modes, and enhanced multipler-divider computation. A 32-bit accumulator is built-in to enable long word processing.
