GENERAL DESCRIPTION This document describes the differences between the ADSP-BF52xC and the ADSP-BF52x standard Blackfin® product. Please refer to the published ADSP-BF52x data sheet for general description and specifications. This document only describes the differences from that data sheet. PROCESSOR FEATURES Up to 600 MHz high performance Blackfin processor RISC-like register and instruction model for ease of programming and compiler-friendly support Advanced debug, trace, and performance monitoring Accepts a wide range of supply voltages for internal and I/O operations. See operating conditions in the published ADSP-BF52x processor data sheet.
