FR60 Lite MB91345 Series

MB91F345B/F346B

■

DESCRIPTION

The MB91345 series is the microcontrollers based on 32-bit high-perform RISC-CPU while integrating a variety

of I/O resources for embedded control applications which require high-performance, high-speed CPU processing.

It is suitable for the embedded control in digital home appliances or audio visual equipment, requiring high-

performance CPU processing power.

This product compactly integrates a variety of peripheral functions for single chip and is FR60 applicable to faster-

speed application.

Note : FR, the abbreviation of FUJITSU RISC controller, is a line of products of FUJITSU Limited.
