■ DESCRIPTION

The FR family* is a line of single-chip microcontrollers based on the 32-bit high-performance RISC CPU while

integrating a variety of I/O resources for embedded control applications which require high-performance, high-

speed CPU processing.

The FR family contains multiple channels of data slicer and communication macros, best suited for embedded

applications such as TV control.

* : FR, the abbreviation of FUJITSU RISC controller, is a line of products of FUJITSU Limited.

■ FEATURES

1. FR CPU

• 32-bit RISC, load/store architecture with a five-stage pipeline

• Operating frequency 33 MHz [PLL used : Oscillation frequency 16.5 MHz : Doubled]

• 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

instructions etc.

• 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

Signed 32-bit multiplication : 5 cycles

Signed 16-bit multiplication : 3 cycles
