■ DESCRIPTION
The FR family* is a series of standard single-chip microcontrollers that feature a variety of built-in I/O resources
andbuscontrolfunctions, andthatemployahigh-performance32-bitRISCCPUforembeddedcontrolapplications
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.
■ FEATURES
1. FR CPU
• 32-bit RISC, load/store architecture with a five-stage pipeline
• Maximum operating frequency : 50 MHz (using the PLL at an oscillation frequency of 12.5 MHz)
• 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
etc.
• Instructions adapted for high-level languages : Function entry/exit instructions, multiple-register load/store
instructions
• Register interlock functions : Facilitate coding in assemblers
