TMS320DM648ZUTD9

Digital Signal Processor Dsp Overview

The TMS320DM648ZUTD9 is a high-performance digital media processor from Texas Instruments, belonging to the C6000 DSP platform. It integrates a C64x+™ DSP core operating at clock rates up to 1.1 GHz (0.91 ns cycle time), delivering up to 8800 MIPS. The device features a two-level cache architecture with 32KB L1P and 32KB L1D memory, plus 512KB of unified L2 mapped RAM/cache. Key peripherals include five configurable video ports, a 3-port Gigabit Ethernet Switch Subsystem with SGMII, DDR2 SDRAM controller, EMIFA, McASP, SPI, I2C, UART, and VLYNQ interface. It utilizes a 529-pin nFBGA package.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix 'D9' against the official datasheet Table 2-1, which lists supported frequencies as 720, 800, 900, and 1100 MHz. Confirm the package type matches the 529-pin Flip Chip Plastic BGA (ZUT) specification. Ensure compliance with the specified voltage requirements: 1.2 V core and 1.8 V/3.3 V I/O.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring fixed-point DSP performance up to 8800 MIPS. The DM648 variant provides 512KB L2 memory, double that of the DM647. Consider the 529-pin ZUT package constraints and the need for 1.2V core power supplies. Verify peripheral availability, as some pins are multiplexed between video ports, GPIO, and other interfaces.

Digital Signal Processor Dsp Part Context

This device is part of the TMS320DM64x family, based on the third-generation VelociTI VLIW architecture. It is upward code-compatible with previous C6000 devices. The DM648 specifically offers enhanced L2 memory capacity compared to the DM647, supporting more complex digital media algorithms.

Digital Signal Processor Dsp Replacement Considerations

TMS320DM647: Offers similar architecture but with 256KB L2 memory and slightly different frequency options. Check pin compatibility and software migration guides for C64x to C64x+ transitions if upgrading from older C64x cores.
