■ DESCRIPTION

The MB90880 series is a general-purpose 16-bit microcontroller, designed by Fujitsu, for process control of devices such as consumer appliances, which require high-speed real-time processing capabilities.

The instruction set of the F2MC-16LX CPU core retains the same AT architecture as the F2MC*1 family, with further refinements including high-level language instructions, an expanded addressing mode, enhanced multiplierdivider instructions and bit processing. In addition, a 32-bit accumulator is built in to enable long word processing.
