www.DataSheet4U.com FUJITSU SEMICONDUCTOR DATA SHEET DS07-16305-2E 32-bit RISC Microcontroller CMOS FR Series MB91107/108 MB91107/108 s DESCRIPTION The MB91107 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 MB91107 normally operates in the external bus access mode and executes instructions on the internal 1 Kbyte cache memory and RAM (MB91107: 128 Kbytes, MB91108: 160 Kbytes) for enhanced performance. The MB91107 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 (Continued) 120-pin Plastic LQFP s PACKAGE (FPT-120P-M21) Da...
