www.DataSheet4U.com FUJITSU SEMICONDUCTOR DATA SHEET DS07-16505-2E Proprietary 32-bit Microcontroller CMOS FR60 MB91310 Series MB91F312A/FV310A s DESCRIPTION The FR families are lines of single-chip microcontrollers based on a 32-bit high-performance RISC CPU, incorporating a variety of I/O resources for embedded control applications which require high CPU performance for high-speed processing. The FR families are best suited for embedded applications which require high-performance CPU power for processing, such as TV and POP control. Based on the FR30/FR40 family CPU, this FR60 family is enhanced in bus access for use in faster applications. s FEATURE FR CPU 32-bit RISC, load/store architecture with a five-stage pipeline Operating frequency: 40 MHz (using PLL at an oscillation frequency of 10 MHz) 16 - bit fixed length instructions (basic instructions), 1 instruction per cycle Instruction set optimized for embedded applications: Memory-to-memory transfer, bit manipulation, barrel shift etc. (Continued) s PACKAGE 144-pin plastic LQFP (FTP-144P-M08) DataSheet 4 U .com www.DataSheet4U.com MB91310 Series Instructions adapted for high-level languages: Function entry/exit instructions, multiple-register load/store instructions Register interlock functions: Facilitating coding in assemblers On-chip multiplier supported at the instruction level.
