32-bit Microcontroller
CMOS
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.
■ 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
