■ DESCRIPTION
The MB91270 series is single chip microcontroller that builds various I/O resources and the bus control mecha-
nisms into by using 32-bit efficient RISC CPU for the built-in control being demanded for CPU processing high per-
formance/high-speed. RAM (for reading data) is included in order to support CPU to access to the vast address
space and to speed up the execution of CPU instructions. This series is optimized to the embedded applications;
automotive applications such as car audio or car air-conditioning equipment that require high-performance CPU
processing power.
It is designed based on the FR-family* CPU.
* : FR, the abbreviation of FUJITSU RISC controller, is a line of products of FUJITSU Limited.
■ FEATURES
• FR CPU characteristics
• 32-bit RISC, load/store architecture with a five-stage pipeline
• Maximum operating frequency: 32 MHz (using the PLL at an oscillation frequency of 4 MHz)
• 16-bit fixed length instructions (basic instructions), 1 instruction per cycle
• Function entry/exit instructions, multiple - register load/store instructions :
Instructions adapted for high - level languages
• Memory-to-memory transfer, bit manipulation, barrel shift instruction etc.:
Instruction optimized for embedded applications
