TMS320DM647CUT7

Digital Signal Processor Dsp Overview

The TMS320DM647CUT7 is a digital media processor from the TMS320DM64x family, manufactured by Texas Instruments. It integrates a C64x+ DSP core operating at up to 1.1 GHz (0.91 ns cycle time), delivering 8800 MIPS. The device features a two-level cache architecture with 32 KB L1P and 32 KB L1D memory, plus 256 KB of unified L2 mapped RAM/cache. Key peripherals include five configurable video ports, a 3-port Gigabit Ethernet switch subsystem with one SGMII port, a 32-bit DDR2 controller, EMIFA, VLYNQ, McASP, SPI, I2C, UART, and PCI. It utilizes a 529-pin nFBGA package and supports 1.2 V core voltage with 1.8 V/3.3 V I/O.

Digital Signal Processor Dsp Procurement Notes

Verify the ordering suffix 'ZUT' corresponds to the 529-pin Flip Chip Plastic BGA package. Confirm the temperature grade matches the required operational range (-40°C to +125°C for industrial). Ensure the specific speed bin (e.g., -1100 for 1.1 GHz) aligns with system timing requirements. Check for RoHS compliance status in the latest datasheet revision.

Digital Signal Processor Dsp Selection Notes

Select this model if the application requires a single-core C64x+ DSP with integrated Gigabit Ethernet switching and extensive video I/O. Compare against TMS320DM648 if higher L2 memory (512 KB) or dual SGMII ports are needed. Verify that the 1.2 V core supply and 1.8 V/3.3 V I/O levels match the board design constraints.

Digital Signal Processor Dsp Part Context

The TMS320DM647CUT7 belongs to the DaVinci Digital Media Processor family, designed for high-throughput video and audio processing. It is part of the TMS320C6000 platform, ensuring code compatibility with previous C64x devices while offering enhanced performance through the C64x+ architecture and additional multimedia peripherals.

Digital Signal Processor Dsp Replacement Considerations

TMS320DM648CUT7 offers similar functionality but includes 512 KB L2 memory and two SGMII ports instead of one. TMS320DM6437 is a lower-performance alternative with a 400 MHz core and different peripheral set. Direct pin-to-pin replacement within the DM647 series is not applicable as it is the base model for this package/speed combination.
