描述

■ DESCRIPTION
The FR family* is a line of microcontrollers based on a high-performance 32-bit RISC CPU that contains a variety of built-in I/O resources for embedded control applications which require high-performance, high-speed CPU processing. MB91313 series has multiple communication macro channels, suitable for embedded control applications such as TV control.■ FEATURES
1. FR CPU
• 32-bit RISC load/store architecture with a five-stage pipeline
• Operating frequency 33 MHz (oscillator frequency: 16.5 MHz; oscillator frequency multiplier: 2 (PLL clock
multiplication method))
• 16-bit fixed length instructions (basic instructions)
• Instruction execution speed : 1 instruction per cycle
• Instructions including memory-to-memory transfer, bit manipulation, and barrel shift instructions : Instructions suitable for embedded applications
• Function entry/exit instructions and register data multi-load store instructions : Instructions supporting C language
• Register interlock functions : Facilitates assembly-language coding
• On-chip multiplier supported at the instruction level
- Signed 32-bit multiplication : 5 cycles
- Signed 16-bit multiplication : 3 cycles
• Interrupt (PC, PS save) : 6 cycles, 16 priority levels
• Harvard architecture enabling program access and data access to be executed simultaneously
• Instruction prefetch feature implemented using a 4-word queue in the CPU
• Instruction compatible with the FR family
