MB90F439 - Brand New FUJITSU Microcontrollers
-
■ DESCRIPTION
The MB90435 series with FLASH ROM is specially designed for industrial applications.
The instruction set by F2MC-16LX CPU core inherits an AT architecture of the F2MC* 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) ) .■ FEATURES
