Device Overview
RC32300 CPU core. This product incorporates a high-performance, low-
cost 32-bit CPU core with functionality common to a large number of
embedded applications. The RC32334 integrates these functions to
enable the use of low-cost PC commodity market memory and I/O
devices, allowing the aggressive price/performance characteristics of
the CPU to be realized quickly into low-cost systems.
