TMS320C6727GDH300

Digital Signal Processor Dsp Overview

The TMS320C6727GDH300 is a floating-point digital signal processor from the C672x family, manufactured by Texas Instruments. It features an enhanced C67x+ CPU operating at a maximum clock frequency of 300 MHz, delivering up to 2400 MIPS and 1800 MFLOPS. The device integrates 256 Kbytes of unified program/data RAM and 384 Kbytes of unified program/data ROM. It operates with a core voltage of 1.2 V and I/O voltage of 3.3 V. The component is housed in a 256-terminal, 1.0-mm, 16x16 mm Plastic Ball Grid Array (PBGA) package.

Digital Signal Processor Dsp Feature Summary

• Enhanced C67x+ CPU with 300 MHz operation, supporting up to eight parallel instructions per cycle including six floating-point operations.
• Integrated memory system comprising 256 Kbytes of RAM and 384 Kbytes of ROM, accessible via a high-performance crossbar switch.
• Universal Host-Port Interface (UHPI) providing a 32-bit-wide data bus for high-bandwidth external host access.
• Three Multichannel Audio Serial Ports (McASP) supporting I2S and TDM formats with transmit/receive clocks up to 50 MHz.

Digital Signal Processor Dsp Applications

• Professional audio processing systems
• Audio mixers and effects boxes
• Audio synthesis and instrument modeling
• Audio conferencing and broadcast equipment

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix GDH against the manufacturer's current documentation to confirm package type and temperature range. Confirm availability status as product lifecycles may change. Ensure compliance with RoHS directives and moisture sensitivity levels specified in the latest datasheet revision before procurement.

Digital Signal Processor Dsp Selection Notes

Select this model when a 300 MHz floating-point performance level is required alongside extensive on-chip memory. The inclusion of UHPI distinguishes it from lower-tier variants like the C6726 or C6722. Ensure the application requires the 256-pin PBGA form factor and can accommodate the 1.2 V core power supply requirements.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C672x series, which includes the C6727, C6726, and C6722. The C6727 variant is distinguished by its 32-bit EMIF width and the presence of the UHPI peripheral. It serves as an upgrade to the previous C67x generation, offering improved code density and floating-point performance while maintaining software compatibility.

Digital Signal Processor Dsp Replacement Considerations

Direct functional replacements within the same package include other speed grades of the C6727 such as the TMS320C6727ZDH300 or TMS320C6727BZDH250. Verify that the pinout and electrical characteristics remain identical when substituting between different suffixes or speed bins.
