TMS320C51PZ57

Digital Signal Processor Dsp Overview

The TMS320C51PZ57 is a 16-bit fixed-point digital signal processor from the Texas Instruments TMS320C5x family, fabricated using static CMOS technology. It features a modular Harvard architecture with single-cycle instruction execution times of 20 ns, 25 ns, 35 ns, or 50 ns for 5-V operation, and 25 ns, 40 ns, or 50 ns for 3-V operation. The device includes 544 words of dual-access DARAM, 512 words of single-access SARAM, 1K word of on-chip ROM, and an addressable external memory space of 224K x 16 bits. It supports full-duplex synchronous serial ports, a buffered serial port, and a host port interface.

Digital Signal Processor Dsp Feature Summary

• Single-cycle 16 × 16-bit multiply/add capability
• On-chip memory: 544-word DARAM, 512-word SARAM, 1K-word ROM
• Full-duplex synchronous serial port and buffered serial port (BSP)
• Host Port Interface (HPI) for direct host access

Digital Signal Processor Dsp Applications

• Coder/decoder interfaces via synchronous serial port
• Time-division-multiplexed (TDM) serial communication
• Control operations utilizing on-chip timer
• Applications requiring Host Port Interface connectivity

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix '57' against the official datasheet to confirm the exact cycle time and voltage rating. Confirm the PZ package designation corresponds to the 100-pin Thin Quad Flat Package. Ensure the component matches the production data specifications published in SPRS030A.

Digital Signal Processor Dsp Selection Notes

Select this device if the application requires the specific memory configuration of 1K ROM and 544 DARAM within the C5x family. Verify that the 100-pin PZ package fits the board layout constraints. Check compatibility with 5-V or 3-V power supplies based on the required execution speed.

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 C51 variant specifically offers a balance of on-chip memory and peripheral interfaces suitable for general-purpose digital signal processing tasks.

Digital Signal Processor Dsp Replacement Considerations

The TMS320LC51 serves as a low-power 3.3-V compatible alternative within the same family. Other C5x variants like the C52 or C53 offer different memory sizes but may require pinout adjustments.
