■ DESCRIPTION
The MB90480B/485B series is a 16-bit general-purpose FUJITSU MICROELECTRONICS microcontroller de-
signed 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 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 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*² interface, DTP/
external interrupt, chip select, and 16-bit reload timer.
*1 : F²MC is the abbreviation of FUJITSU Flexible Microcontroller.
*2 : Purchase of Fujitsu I²C components conveys a license under the Philips I²C Patent Rights to use, these com-
ponents in an I²C system provided that the system conforms to the I²C standard a Specification as defined by
Philips.
