DESCRIPTION

The MB90820 series is a line of general-purpose, Fujitsu 16-bit microcontrollers designed for process control applications which require high-speed real-time processing, such as consumer products. While inheriting the AT architecture of the F²MC*1 family, the instruction set for the F2MC-16LX CPU core of the MB90820 series incorporates additional instructions for high-level languages, supports extended addressing modes, and contains enhanced multiplication and division instructions as well as a substantial collection of improved bit manipulation instructions. In addition, the MB90820 series has an on-chip 32-bit accumulator which enables processing of long-word data. The peripheral resources integrated in the MB90820 series include: an 8/10-bit A/D converter, 8-bit D/A converters, UARTs (SCI) 0 to 1, multi-functional timer (16-bit free-running timer, input capture units (ICUs) 0 to 3, output compare units (OCUs) 0 to 5, 16-bit PPG timer 0, waveform generator), 16-bit PPG timer 1 to 2, PWC 0 to 1, 16-bit reload timer 0 to 1 and DTP/external interrupt.
