TMS320DM647CUT9

Digital Signal Processor Dsp Overview

The TMS320DM647CUT9 is a digital media processor from the TMS320DM64x family, manufactured by Texas Instruments. It integrates a C64x+ DSP core operating at a maximum clock frequency of 1100 MHz, delivering up to 8800 MIPS performance. The device features a two-level cache architecture with 32 KB L1P and 32 KB L1D memory, alongside 256 KB of unified L2 mapped RAM/cache. Key peripherals include five configurable video ports, a 3-port Gigabit Ethernet switch subsystem, DDR2 SDRAM controller, EMIFA, VLYNQ interface, McASP, UART, SPI, I2C, and PCI. It utilizes a 529-pin nFBGA package (ZUT suffix) and operates with 1.2 V core voltage and 1.8 V/3.3 V I/O voltages.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix '9' corresponds to the 1100 MHz operational frequency as defined in the device characteristics table. Confirm the ZUT package designation matches the required 529-pin nFBGA form factor. Ensure compatibility with 1.2 V core and 1.8 V/3.3 V I/O power requirements during system design validation.

Digital Signal Processor Dsp Selection Notes

Select this model for applications requiring high-performance fixed-point DSP processing with integrated video interfaces. The DM647 variant provides 256 KB L2 memory, suitable for code-intensive or moderate data-buffering tasks compared to the DM648's 512 KB L2. Consider the 1100 MHz speed grade if maximum instruction throughput is critical for real-time video decoding or encoding algorithms.

Digital Signal Processor Dsp Part Context

The TMS320DM647CUT9 belongs to the TMS320DM64x Digital Media Processor series, which extends the TMS320C6000 platform. It shares architectural similarities with the TMS320DM648 but differs in L2 memory capacity (256 KB vs 512 KB). The device is part of the DaVinci technology family, designed specifically for complex digital media applications leveraging the advanced C64x+ VLIW architecture.

Digital Signal Processor Dsp Replacement Considerations

TMS320DM648CUTA8 offers similar functionality with increased L2 memory (512 KB) and an additional SGMII port, but requires verification of pin-to-pin compatibility and software adaptation for the different memory map and peripheral availability.
