Overview
The TMS320C53SPZ is a digital signal processor (DSP) from Texas Instruments, part of the TMS320C5x generation. This DSP is fabricated using advanced static CMOS integrated circuit technology and is based on the architectural design of the earlier TMS320C25 DSP. The TMS320C53SPZ combines a powerful 16-bit CPU with on-chip peripherals, memory, and a highly specialized instruction set, enabling high performance and versatility.
The device executes up to 50 million instructions per second (MIPS) and features single-cycle instruction execution times of 20-, 25-, 35-, and 50-ns for 5-V operation and 25-, 40-, and 50-ns for 3-V operation. It also includes a single-cycle 16 × 16-bit multiply/add capability.
