F2MC-16LX MB90435 Series

MB90437L (S) /438L (S) /F438L (S)

MB90439 (S) /F439 (S) /V540G

■ 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
