DESCRIPTION
The FR family* is a series of standard single-chip microcontrollers that feature a variety of built-in I/O resources
and bus control functions, and that employ a high-performance 32-bit RISC CPU for embedded control applications
that demand powerful and fast CPU processing capabilities.
This product is one of the FR60 family based on the FR30/40 family CPU with enhanced bus access. The FR60
family is a line of single-chip oriented microcontrollers that incorporate a wealth of peripheral resources.
The FR60 family is optimized for embedded control applications that require high CPU processing power, such
as DVD players, navigation equipment, high performance fax machines, and printer controllers.
* : FR, the abbreviation of FUJITSU RISC controller, is a line of products of FUJITSU Limited.
