TMS320C53SPZ

Digital Signal Processor Dsp Overview

The TMS320C53SPZ is a 16-bit digital signal processor from the Texas Instruments TMS320C5x family, fabricated using high-performance static CMOS technology. It features a single-cycle 16 × 16-bit multiply/add unit and supports execution times of 50 ns, 35 ns, or 25 ns for 5-V operation. The device includes 3K × 16-bit on-chip program ROM and 16K × 16-bit single-access SARAM. It provides a maximum addressable external memory space of 224K × 16 bits and incorporates full-duplex synchronous serial ports, a buffered serial port, and a host port interface.

Digital Signal Processor Dsp Applications

• Industrial control systems requiring real-time processing
• Data communications equipment utilizing serial interfaces
• Consumer electronics applications demanding low power consumption
• Automotive embedded control modules

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix corresponding to the required cycle time (50 ns, 35 ns, or 25 ns). Confirm package compatibility with the 100-pin Thin Quad Flat Package (PZ suffix) design. Ensure voltage supply requirements match the 5-V operational specification for this part variant.

Digital Signal Processor Dsp Selection Notes

Select based on on-chip memory needs, as this model contains 3K ROM and 16K SARAM. Consider the 100-pin PZ package constraint if board space is limited compared to the 132-pin PQ option. Evaluate PLL clocking requirements against available external oscillator frequencies.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C5x generation of DSPs, which are upward-compatible with source code from earlier TMS320C1x and C2x devices. The architecture utilizes an advanced Harvard design optimized for high-speed digital signal processing tasks within a modular framework.

Digital Signal Processor Dsp Replacement Considerations

TMS320LC53S offers a 3.3-V compatible alternative with identical memory and peripheral configurations in the same 100-pin package.
