s 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.
s FEATURES
FR CPU
• 32-bit RISC, load/store architecture, 5-stage pipeline
