■ OVERVIEW
MB91245/S series is Fujitsu’s general-purpose 32-bit RISC microcontroller, which is designed for embedded control applications that require high-speed real-time processing of consumer appliances. This microcontroller uses FR60Lite as its CPU, compatible with other products in the FR* family. This series incorporates an LCD controller and stepping motor controller. * : FR, the abbreviation of FUJITSU RISC controller, is a line of products of FUJITSU Limited.
■ FEATURES
FR60Lite CPU 32-bit RISC, load/store architecture, 5-stage pipeline Maximum operating frequency : 32 MHz (Source oscillation is 4 MHz with x8 multiplier – PLL clock multiplier system) 16-bit fixed-length instructions (basic instructions) Instruction execution speed : 1 instruction per cycle Instruction set optimized for embedded application : Memory-to-memory transfer, bit manipulation, barrel shift instructions etc. Instructions adapted for programming C language : Function entry/exit instructions, multiple-register load/store instructions.
