32-bit FR Family
■
FR Family Features
• CPU core capable of running at a peak rate of 64 VAX MIPS (CPU core performance) at 50 MHz while featuring
its compactness equivalent to 16-bit microcontrollers
• 5-stage pipelining and harvard-bus architecture, allowing efficient execution
• Implementation of, basically, 16-bit fixed length commands, providing high object code efficiency
• The command group enhanced for controllers and an algorithm engine, resulting in faster execution of instruc-
tions
• A variety of resources including the sum-of-product units
• Many kinds of internal peripheral devices
• FR architecture features
• Fujitsu embedded RISC controller
The FR family is designed for optimum use in control systems while the SPARClite is suitable for data
processing systems.
