DESCRIPTION
The MB90435 series with FLASH ROM is specially designed for industrial applications.
The instruction set by 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 micro controller has a 32-bit accumulator for processing
long word data.
The MB90435 series has peripheral resources of 8/10-bit A/D converters, UART (SCI) , extended I/O serial
interfaces, 8/16-bit timer, I/O timer (input capture (ICU) , output compare (OCU) ) .
