■
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.
• Register interlock function : Easier assembler coding enabled
• Built-in multiplier supported at the instruction level
Signed 32-bit multiplication : 5 cycles
Signed 16-bit multiplication : 3 cycles
