■DESCRIPTION

The MB90480B/485B series is a 16-bit general-purpose FUJITSU SEMICONDUCTOR microcontroller designed for process control in consumer devices and other applications requiring high-speed real-time processing.

The F2MC-16LX CPU core instruction set retains the AT architecture of the F2 MC*1

family, with additional instructions for high-level languages, expanded addressing mode, enhanced multiply-drive instructions, and complete bit processing. In addition, a 32-bit accumulator is provided to enable long-word processing.

The MB90480B/485B series features embedded peripheral resources including 8/16-bit PPG, expanded I/O serial interface, UART, 10-bit A/D converter, 16-bit I/O timer, 8/16-bit up/down-counter, PWC timer, I2C interface, DTP/external interrupt, chip select, and 16-bit reload timer.
