MC-16LX MB90590G Series
MB90591G/F591G/594G/F594G/V590G
■
DESCRIPTION
The MB90590G series with two FULL-CAN interfaces and FLASH ROM is especially designed for automotive
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 F
2
MC-16LX CPU core inherits an AT architecture of the F
2
MC* family with additional
instruction sets for high-level languages, extended addressing mode, enhanced multiplication/division instruc-
tions, and enhanced bit manipulation instructions. The microcontroller has a 32-bit accumulator for processing
long word data.
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.
