TMS320C51PQ100

Digital Signal Processor Dsp Overview

The TMS320C51PQ100 is a 16-bit digital signal processor from the Texas Instruments TMS320C5x family, housed in a 132-pin Quad Flat Package (PJ suffix). It features a powerful CPU capable of single-cycle 16 × 16-bit multiply/add operations. The device supports execution times of 50 ns, 35 ns, and 25 ns for 5-V operation. It includes 544 words of dual-access DARAM, 512 words of single-access SARAM, and 8K words of on-chip ROM. The architecture provides a maximum addressable external memory space of 224K × 16 bits.

Digital Signal Processor Dsp Feature Summary

• Single-cycle 16 × 16-bit multiply/add capability
• On-chip memory: 544-word DARAM, 512-word SARAM, 8K-word ROM
• Supports full-duplex synchronous serial port and time-division-multiplexed serial port
• Hardware or software wait-state generation capability

Digital Signal Processor Dsp Applications

• Coder/decoder interface applications via full-duplex synchronous serial port
• Control operations utilizing the on-chip timer
• Data and program management using block move instructions

Digital Signal Processor Dsp Procurement Notes

Verify the package suffix PJ corresponds to the 132-pin Quad Flat Package configuration. Confirm the operating voltage requirements align with the 5-V specification for this specific model variant. Ensure that the ordering information matches the exact part number TMS320C51PQ100 to guarantee correct pinout and electrical characteristics.

Digital Signal Processor Dsp Selection Notes

Select this component when a 16-bit DSP with on-chip ROM is required for fixed-function applications. The TMS320C51 offers upward-compatible source code with earlier C1x and C2x devices. Consider the available packaging options if pin count constraints differ; other variants like the PZ package offer 100 pins.

Digital Signal Processor Dsp Part Context

This device belongs to the TMS320C5x generation of digital signal processors fabricated with static CMOS technology. It is based on the architectural design of the TMS320C25. The family includes various models such as the TMS320C50, C52, and C53, which differ primarily in on-chip memory sizes and package types.

Digital Signal Processor Dsp Replacement Considerations

The TMS320LC51 is a low-power 3.3-V version of the same core architecture. For pin-compatible alternatives within the 100-pin form factor, consider the TMS320C52 or TMS320LC52, though they lack the on-chip ROM found in the C51.
