The MB90570 series is a general-purpose 16-bit microcontroller developed and designed by Fujitsu for process control applications in consumer products that require high-speed real time processing. It contains an I2C*2 bus interface that allows inter-equipment communication to be implemented readily. This product is well adapted to car audio equipment, VTR systems, and other equipment and systems. The instruction set of F2MC-16LX CPU core inherits AT architecture of F2MC*1 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.
