■DESCRIPTION

The MB91106 is a standard single-chip microcontroller constructed around the 32-bit RISC CPU (FR* family) core with abundant I/O resources and bus control functions optimized for high-performance/high-speed CPU processing for embedded controller applications. To carry out hi-speed performance of CPU instructions, instruction/data ROM of 64 Kbytes and RAM of 2 Kbytes are embedded in the MB91106. The MB91101 is optimized for applications requiring high-performance CPU processing such as navigation systems, high-performance FAXs and printer controllers.

*: FR Family stands for FUJITSU RISC controller.
