Texas Instruments TMS320C5x/TMS320LC5x Digital Signal Processors Data Sheet
This document provides a comprehensive overview of the TMS320C5x generation of Digital Signal Processors (DSPs) from Texas Instruments. The devices are fabricated with static CMOS technology and feature an enhanced Harvard architecture based on the earlier TMS320C25 design. Key capabilities include powerful 16-bit CPU performance, single-cycle instruction execution times ranging from 20 to 50 nanoseconds depending on voltage and device speed, and a specialized instruction set optimized for high-level language operation.
