com FUJITSU SEMICONDUCTOR DATA SHEET DS07-16301-2E 32-bit RISC Microcontroller CMOS FR30 Series MB91101/MB91101A s DESCRIPTION The MB91101 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 support the vast memory space accessed by the 32-bit CPU, the MB91101 normally operates 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 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 Operating clock frequency: Internal 50 MHz/external 25 MHz (PLL used at source oscillation 12.
