16-bit Proprietary Microcontroller
F2MC-16LX MB90980 Series
The MB90980 series is a 16-bit general-purpose FUJITSU microcontroller designed for process control in con-
sumer devices and other applications requiring high-speed real-time processing.
The F2MC-16LX CPU core instruction set retains the AT architecture of the F2MC*1 family, with additional instruc-
tions 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 MB90980 series features embedded peripheral resources including 8/16-bit PPG, expanded I/O serial inter-
face, UART, 10-bit A/D converter, 16-bit I/O timer, 8/16-bit up/down-counter, PWC timer, I2C*2 interface, DTP/
external interrupt, chip select, and 16-bit reload timer.
