■ 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) ) .
* : F²MC is the abbreviation of FUJITSU Flexible Microcontroller.
■ FEATURES
• Clock
Embedded PLL clock multiplication circuit
Operating clock (PLL clock) can be selected from : divided-by-2 of oscillation or one to four times the oscillation
Minimum instruction execution time : 62.5 ns (operation at oscillation of 4 MHz, four times the oscillation clock,
VCC of 5.0 V)
Subsystem Clock : 32 kHz
