■ 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
