TMS320LBC51PZ57

Digital Signal Processor Dsp Overview

The TMS320LBC51PZ57 is a member of the Texas Instruments TMS320LC5x generation of 16-bit digital signal processors. It utilizes static CMOS technology and features a powerful 16-bit CPU capable of single-cycle 16 × 16-bit multiply/add operations. The device supports execution times of 25, 40, or 50 ns for 3-V operation. It provides up to 224K × 16-bit addressable external memory space and includes on-chip program ROM (2K–32K words) and RAM (1K–9K words). Key peripherals include full-duplex synchronous serial ports, a time-division-multiplexed serial port, a buffered serial port, and a host port interface.

Digital Signal Processor Dsp Feature Summary

• 16-bit Harvard architecture with single-cycle 16 × 16-bit multiply/add capability
• On-chip memory including single-access Program/Data RAM and Program ROM
• Multiple serial interfaces: Full-Duplex Synchronous Serial Port, TDM Serial Port, and Buffered Serial Port
• Host Port Interface (HPI) for direct connection to host microprocessors
• IEEE Standard 1149.1 Test-Access Port (JTAG) and on-chip scan-based emulation logic

Digital Signal Processor Dsp Applications

• Digital cellular system channel equalization
• Coder/decoder interface applications
• Control operations utilizing on-chip timers
• Host processor interfacing via HPI

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'PZ57' against official documentation, as standard datasheets list package suffixes such as PZ (100-Pin Thin Quad Flat Package) but do not explicitly define the '57' designation within the provided text. Confirm power supply requirements (3.3 V for LC5x devices) and operating temperature ranges prior to procurement.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring 16-bit DSP performance with low power consumption at 3 V operation. Ensure the design accommodates the 100-pin thin QFP package if the PZ suffix is confirmed. Consider the available on-chip memory sizes (ROM and RAM) to determine if external memory expansion is necessary for the target application.

Digital Signal Processor Dsp Part Context

This device belongs to the TMS320C5x/LC5x family, which offers upward-compatible source code with earlier C1x and C2x DSPs. The LC5x variants are optimized for 3.3 V operation, providing lower power dissipation compared to the 5 V C5x counterparts while maintaining similar architectural features and instruction sets.

Digital Signal Processor Dsp Replacement Considerations

TMS320C51PZ57: Equivalent 5 V variant with identical pinout and functionality, differing only in supply voltage and execution speed specifications.
