TMS320DM647ZUT1

Digital Signal Processor Dsp Overview

The TMS320DM647ZUT1 is a digital media processor based on the C64x+ DSP core, operating at clock rates up to 1.1 GHz with an instruction cycle time of 0.91 ns. It delivers up to 8800 MIPS performance and features a two-level cache architecture comprising 32KB L1P, 32KB L1D, and 256KB unified L2 memory. The device integrates five configurable video ports, a 3-port Gigabit Ethernet switch subsystem, and multiple peripherals including EDMA3, UART, SPI, I2C, McASP, HPI, PCI, and VLYNQ. It utilizes a 529-pin nFBGA package (ZUT suffix) and operates with 1.2V core voltage and 1.8V/3.3V I/O.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix corresponding to the required clock frequency (e.g., -720, -900, or -1100) as the base model number does not specify it. Confirm RoHS compliance status for the specific manufacturing lot. Ensure compatibility with the 529-pin BGA footprint and thermal requirements during procurement planning.

Digital Signal Processor Dsp Selection Notes

Select the appropriate speed grade suffix based on the target system clock frequency requirements. Compare against the TMS320DM648 if 512KB of L2 memory is necessary instead of the DM647's 256KB. Verify that the peripheral pin multiplexing options meet the design's connectivity needs, particularly for the shared GPIO and video port functions.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320DM64x family of digital media processors from Texas Instruments. It shares the same 529-pin ZUT package and core architecture as the TMS320DM648, differing primarily in the amount of on-chip L2 memory (256KB vs 512KB). It is part of the C6000 DSP platform designed for high-performance fixed-point processing.

Digital Signal Processor Dsp Replacement Considerations

The TMS320DM648 is a direct architectural alternative within the same package offering higher L2 memory capacity. Other C64x+ devices in the C6000 family may require significant schematic and software modifications due to peripheral differences.
