s DESCRIPTION
The MB91F109 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 Flash memory of 254 Kbytes and RAM of 2 Kbytes + 2 Kbytes are embedded in the MB91F109. The MB91F109 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.
