www.DataSheet4U.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 12.5 MHz) General purpose registers: 32 bits × 16 16-bit fixed length instructions (basic instructions), 1 instruction/1 cycle Memory to memory transfer, bit processing, barrel shifter processing: Optimized for embedded applications Function entrance/exit instructions, multiple load/store instructions of register contents, instruction systems supporting high level languages Register interlock functions, efficient assembly language coding Branch instructions with delay sl...
