TMS320BC53SPZ80

Digital Signal Processor Dsp Overview

The TMS320BC53SPZ80 is a member of the Texas Instruments TMS320C5x generation of digital signal processors. It features a powerful 16-bit CPU capable of single-cycle 16 × 16-bit multiply/add operations and up to 50 million instructions per second (MIPS). The device provides an addressable external memory space of 224K × 16 bits, including on-chip program ROM and RAM options. It supports multiple clocking options via internal phase-locked loops and includes peripherals such as full-duplex synchronous serial ports, time-division-multiplexed serial ports, and a host port interface.

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'PZ' corresponds to the 100-pin Thin Quad Flat Package (TQFP) as defined in the TMS320C5x datasheet. Confirm voltage requirements; 'LC' variants operate at 3.3V while standard 'C' variants typically require 5V. Ensure the ordering code matches the exact memory configuration and package type required for the design.

Digital Signal Processor Dsp Selection Notes

Select based on required on-chip memory size (ROM/SARAM) and package pin count. The 'S' suffix often denotes a specific package variant or feature set within the C5x family. Compare against other C5x devices like the TMS320C50 or C51 if different memory capacities or peripheral sets are needed. Verify clock frequency requirements against the 20ns, 25ns, 35ns, or 50ns cycle time options available.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C5x DSP family, which succeeded the TMS320C25 architecture. It offers upward-compatible source code with earlier C1x and C2x DSPs. The family is characterized by its Harvard architecture, specialized instruction set, and static CMOS technology designed for low power dissipation and high performance.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same package and voltage domain include other TMS320C53 or TMS320LC53 variants. For broader compatibility, consider TMS320C50, C51, or C52 devices, noting differences in on-chip memory and peripheral availability such as the Host Port Interface.
