TMS320C6727ZDHA250

Digital Signal Processor Dsp Overview

The TMS320C6727ZDHA250 is a floating-point digital signal processor from the TMS320C672x family, manufactured by Texas Instruments. It features an enhanced C67x+ CPU operating at a maximum clock frequency of 250 MHz. The device integrates 256 Kbytes of unified program/data RAM and 384 Kbytes of unified program/data ROM. Key peripherals include three Multichannel Audio Serial Ports (McASP), a Universal Host-Port Interface (UHPI) with a 32-bit data bus, two SPI ports, two I2C ports, and an External Memory Interface (EMIF) supporting 32-bit SDRAM. The processor operates on a 1.2 V core voltage and 3.3 V I/O voltage, housed in a 256-terminal PBGA package.

Digital Signal Processor Dsp Feature Summary

• Enhanced C67x+ CPU with up to eight parallel instructions per cycle at 250 MHz
• Unified memory system comprising 256 KB RAM and 384 KB ROM
• Universal Host-Port Interface (UHPI) for high-bandwidth external host access
• Three Multichannel Audio Serial Ports (McASP) supporting I2S and TDM formats

Digital Signal Processor Dsp Applications

• Professional audio processing and mixing
• Active acoustic noise cancellation systems
• Audio encoding and decoding algorithms
• Audio conferencing and broadcast equipment

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'A' against the official datasheet to confirm temperature range or revision details, as standard documentation primarily lists ZDH variants. Confirm availability status directly with Texas Instruments or authorized distributors, as production status may vary. Ensure compliance with RoHS directives and moisture sensitivity level (MSL) handling requirements during assembly.

Digital Signal Processor Dsp Selection Notes

Select this model when a 250 MHz execution speed is sufficient for the target algorithm, offering a cost-effective alternative to the 300 MHz variant. The presence of UHPI distinguishes it from lower-tier models like the C6726 or C6722. Ensure the design accommodates the 1.2 V core power supply and utilizes the 32-bit EMIF width available only on the C6727 series.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C672x series, which upgrades the previous C67x architecture. It shares the same package and peripheral set as the TMS320C6727BZDH250 but may differ in manufacturing revision or specific electrical characteristics defined by the 'A' suffix. It is part of the broader TMS320C6000 family designed for high-performance floating-point applications.

Digital Signal Processor Dsp Replacement Considerations

The TMS320C6727BZDH250 is a direct functional equivalent within the same package and feature set. The TMS320C6727ZDH300 offers higher performance at 300 MHz but requires verification of thermal and power constraints. Lower-speed variants such as the C6726 or C6722 lack the UHPI interface and have narrower EMIF buses.
