TMS320BC51PQ

Digital Signal Processor Dsp Overview

The TMS320BC51PQ is a member of the Texas Instruments TMS320C5x generation of digital signal processors. It utilizes a powerful 16-bit CPU architecture based on advanced static CMOS technology, enabling single-cycle instruction execution times of 20 ns, 25 ns, 35 ns, or 50 ns depending on the specific speed grade and voltage supply. The device features a highly specialized instruction set optimized for high-speed algorithms and includes on-chip memory resources such as SARAM and DARAM to support efficient data processing.

Digital Signal Processor Dsp Feature Summary

• 16-bit Harvard architecture with single-cycle 16 × 16-bit multiply/add capability
• Execution speeds ranging from 20 ns to 50 ns per machine cycle
• On-chip memory including 1K × 16-bit SARAM and 8K × 16-bit ROM
• Integrated full-duplex synchronous serial port and time-division-multiplexed (TDM) serial port

Digital Signal Processor Dsp Applications

• Digital audio signal processing
• Modem and codec interface applications
• Real-time control systems requiring fast algorithmic execution

Digital Signal Processor Dsp Procurement Notes

Verify the exact speed grade suffix (e.g., -20, -25, -35, -50) required for the target clock frequency. Confirm that the PQ package (132-pin Quad Flat Package) matches the PCB footprint design. Ensure power supply requirements align with the 5-V operation specifications typical for the C51 variant.

Digital Signal Processor Dsp Selection Notes

Select this component when a balance of moderate on-chip memory and high processing speed is needed. The TMS320C51 offers 8K ROM and 1K SARAM, suitable for applications where code size exceeds smaller variants but does not require the larger memory maps of the C53 or C57. Consider the 132-pin package density for board layout constraints.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320C5x family, which succeeded the TMS320C25. The C5x generation introduced enhanced performance through static CMOS technology and an expanded instruction set. The 'BC' designation typically indicates a specific manufacturing lot or temperature range variant within the commercial C51 line, housed in the PQ package.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-compatible replacements within the same package include other TMS320C51 variants with different speed grades (e.g., TMS320C51PQ-25). For upward compatibility, source code written for TMS320C1x and TMS320C2x DSPs can be reused.
