TMS320C6727ZDH250

Digital Signal Processor Dsp Overview

The TMS320C6727ZDH250 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 250 MHz. The device integrates 256 Kbytes of unified program/data RAM and 384 Kbytes of unified program/data ROM. It utilizes a 256-terminal PBGA package with dimensions of 17x17 mm. The core operates at 1.2 V, while I/O pins support 3.3 V levels. Key peripherals include three Multichannel Audio Serial Ports (McASP), two SPI ports, two I2C ports, a Universal Host-Port Interface (UHPI), and a Dual Data Movement Accelerator (dMAX).

Digital Signal Processor Dsp Feature Summary

• Enhanced C67x+ CPU with up to eight parallel instructions per cycle at 250 MHz.
• Unified memory architecture comprising 256 KB RAM and 384 KB ROM.
• Universal Host-Port Interface (UHPI) supporting high-bandwidth parallel data transfers.
• Dual Data Movement Accelerator (dMAX) for concurrent data transfer requests.

Digital Signal Processor Dsp Applications

• Professional audio mixers and effects boxes.
• Audio synthesis and instrument/amplifier modeling.
• Active acoustic noise cancellation systems.
• Audio conferencing and broadcast equipment.

Digital Signal Processor Dsp Procurement Notes

Verify the specific ordering suffix ZDH250 against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure that the 256-terminal PBGA package dimensions align with the target PCB footprint. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly planning.

Digital Signal Processor Dsp Selection Notes

Select this component when a 32-bit/64-bit floating-point DSP with a 250 MHz clock speed is required. The presence of the UHPI interface distinguishes it from lower-tier models like the C6726 or C6722. Ensure the design accommodates the 1.2 V core voltage and 3.3 V I/O voltage requirements. Verify that the 256-pin BGA package is suitable for the manufacturing capabilities of the production facility.

Digital Signal Processor Dsp Part Context

This part 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 inclusion of the UHPI peripheral. The 'ZDH' suffix indicates the 256-terminal PBGA package, while '250' denotes the 250 MHz speed grade. This series represents an upgrade to the previous C67x generation with improved code density and performance.

Digital Signal Processor Dsp Replacement Considerations

Direct functional substitutes within the same package and speed grade are not explicitly listed in the provided documentation. The TMS320C6727ZDH300 offers identical functionality but operates at a higher 300 MHz frequency. Other members of the C672x family, such as the C6726 or C6722, lack the UHPI interface and have different EMIF widths, requiring significant hardware redesign if used as replacements.
