TMS320DM642AGNZ7

Digital Signal Processor Dsp Overview

The TMS320DM642AGNZ7 is a video/imaging fixed-point digital signal processor based on the C64x+ DSP core. It operates at clock rates of 500, 600, or 720 MHz, delivering up to 5760 MIPS. The device features VelociTI.2 extensions for advanced VLIW parallelism, supporting quad 8-bit and dual 16-bit arithmetic per cycle. It includes three configurable video ports (VP0–VP2), a 10/100 Mb/s Ethernet MAC, McASP, McBSP, I2C, PCI, and an EMIF. The GNZ suffix indicates support for big-endian mode and utilizes a 548-pin BGA package with a 1.0-mm ball pitch.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade (-500, -600, or -720) required for the application, as performance varies by clock rate. Confirm that the 1.0-mm pitch 548-pin BGA package fits the PCB layout constraints. Ensure the design supports the 1.2V core voltage and 3.3V I/O requirements specified in the datasheet electrical characteristics.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring high-throughput video processing and network integration. The GNZ suffix is necessary if big-endian memory mode is required. Compare against DM643 or DM644 if additional peripherals like USB or higher-speed interfaces are needed. Ensure the development environment supports the C6000 toolchain for code compilation.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320DM64x family of digital media processors from Texas Instruments. It shares architectural similarities with other C64x-based devices but is optimized for video and imaging tasks. The GNZ variant specifically denotes the package type and endianness configuration within the broader DM642 product line.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacements may include other DM642 variants with different speed grades or package pitches (e.g., ZDK). For upgraded functionality, consider the DM644 or DM6467 series, though these require schematic and software modifications due to peripheral differences.
