FR8052
PIPELINED HIGH PERFORMANCE 8-BIT MICROCONTROLLER
Version 1.6 | March 2006
General Description
FR8052 is an ultra high performance, speed optimized hard core of a single-chip 8-bit embedded controller dedicated for
operation with fast (typically on-chip) and slow (off-chip) memories.
FR8052 hard core is 100% binary-compatible with the industry standard 8051 8-bit microcontroller. FR8052 has Pipelined
RISC architecture 10 times faster than the standard architecture.
