The MB90570/A 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 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 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 MB90570/A series has peripheral resources of an 8/10-bit A/D converter, an 8-bit D/A converter, UART (SCI), an extended I/O serial interface, an 8/16-bit up/down counter/timer, an 8/16-bit PPG timer, I/O timer (a 16-bit free run timer, an input capture (ICU), an output compare (OCU)).
