Description
The FUJITSU FR family of single-chip microcontrollers using a 32-bit high-performance RISC CPU, with a variety of built-in I/O resources and bus control mechanisms for built-in control applications requiring high-capability, high-speed CPU processing.
Key Features
- 32-bit RISC, load/store architecture, 5-stage pipeline
- Operating frequency 66MHz [with PLL: base frequency 16.5 MHz]
- 16-bit fixed length instructions (basic instructions), 1 instruction per cycle
- Instructions for built-in applications: memory-to-memory transfer, bit processing, barrel shift etc
- Easier assembler notation: register interlock function
- Built-in multiplier/instruction level support Signed 32-bit multiplication: 5 cycles Signed 16-bit multiplication: 3 cycles
- Interrupt (PC, PS removal): 6 cycles, 16 priority levels
- Harvard architecture for simultaneous execution of program access and data access
- CPU hold 4-word queue allows advanced instruction fetch function
- 4G bytes expanded memory space enables linear access
