■ 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.
■ FEATURE
