16-bit Proprietary Microcontroller
F2MC-16LX MB90590/590G Series
The MB90590/590G series with two FULL-CAN*1 interfaces and FLASH ROM is especially designed for automo-
tive and industrial applications. Its main features are two on board CAN Interfaces, which conform to V2.0 Part A
and Part B, while supporting a very flexible message buffer scheme and so offering more functions than a normal
full CAN approach.
The instruction set of F2MC-16LX CPU core inherits an AT architecture of the F2MC*2 family with additional
instruction sets for high-level languages, extended addressing mode, enhanced multiplication/division instructions,
and enhanced bit manipulation instructions. The microcontroller has a 32-bit accumulator for processing long
The MB90590/590G series has peripheral resources of 8/10-bit A/D converters, UART (SCI), extended I/O serial
interface, 8/16-bit PPG timer, I/O timer (input capture (ICU), output compare (OCU)), stepping motor controller,
and sound generator.
