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.

■ FEATURE

• FR CPU

• 32-bit RISC, load/store architecture, with a five-stage pipeline

• Maximum operating frequency : 50 MHz [PLL used : original oscillation 12.5 MHz]

• 16-bit fixed length instruction (basic instructions) ; 1 instruction per cycle

• Instruction set optimized for embedded applications : Memory-to-Memory transfer, bit manipulation, barrel shift

instructions

• Instructions adapted for high-level programming languages : Function entry/exit instructions, multiple-register

load/store instructions

• Register interlock function : Facilitating coding in assembles
