MB91101/MB91101A
s DESCRIPTION
The MB91101 and MB91101A are 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 support the vast memory space accessed
by the 32-bit CPU, the MB91101 and MB91101A normally operate in the external bus access mode and executes
instructions on the internal 1 Kbyte cache memory and 2 Kbytes RAM for enhanced performance.
The MB91101 and MB91101A are 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.
