DESCRIPTION

The MB90570 series is a general-purpose 16-bit microcontroller developed and designed by Fujitsu for process
control applications in consumer products that require high-speed real time processing. It contains an I

bus

interface that allows inter-equipment communication to be implemented readily. This product is well adapted to
car audio equipment, VTR systems, and other equipment and systems.

The instruction set of F

MC-16LX CPU core inherits AT architecture of F

MC*

family with additional instruction

sets for high-level languages, extended addressing mode, enhanced multiplication/division instructions, and en-
hanced bit manipulation instructions. The microcontroller has a 32-bit accumulator for processing long word data.

The MB90570 series has peripheral resources of an 8/10-bit A/D converter, an 8-bit D/A converter, UART (SCI),
an extended I/O serial interface, an 8/16-bit up/down counter/timer, an 8/16-bit PPG timer, I/O timer (a 16-bit free
run timer, an input capture (ICU), an output compare (OCU)).

MC stands for FUJITSU Flexible Microcontroller.

*2: Purchase of Fujitsu I

C components conveys a license under the Philips I

C Patent Rights to use these

components in an I

C system, provided that the system conforms to the I

C Standard Specification as

defined by Philips.
