The MB90520 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. The microcontroller has a 32-bit accumulator for processing long word data. The MB90520 series has peripheral resources of 8/10-bit A/D converter, 8-bit D/A converter, UART (SCI), extended I/O serial interfaces 0 and 1, 8/16-bit up/down counter/timers 0 and 1, 8/16-bit PPG timers 0 and 1, I/O timer (16-bit free-run timers 1 and 2, input captures 0 and 1 (ICU), output compares 0 and 1 (OCU)), and an LCD controller/driver.
The MB90520 series is a general-purpose 16-bit microcontroller developed by Fujitsu for process control applications in consumer products requiring high-speed real-time processing. It utilizes the F2MC-16LX CPU core, which inherits the AT architecture of the F2MC* family with additional instruction sets for high-level languages, extended addressing modes, and enhanced multiplication/division instructions.
