TMS320DM648ZUTD1

Digital Signal Processor Dsp Overview

The TMS320DM648ZUTD1 is a digital media processor from the TMS320DM64x family, manufactured by Texas Instruments. It integrates a C64x+ DSP core operating at frequencies up to 1.1 GHz (0.91 ns cycle time), delivering up to 8800 MIPS. The device features 512 KB of L2 unified mapped RAM/cache and 32 KB each for L1P and L1D memory. Key peripherals include five configurable video ports, a 3-port Gigabit Ethernet switch subsystem with two SGMII ports, DDR2 and EMIFA controllers, and standard interfaces like UART, SPI, I2C, McASP, and PCI. It utilizes a 529-pin nFBGA package.

• Internet video protocol servers
• Machine vision systems

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (e.g., D1) against the datasheet Table 2-1 to confirm the maximum operating frequency and temperature range. Ensure compatibility with the 529-pin ZUT package dimensions and pinout. Confirm power supply requirements for the 1.2 V core and 1.8 V/3.3 V I/O domains during design-in.

Digital Signal Processor Dsp Selection Notes

Select this model for high-performance fixed-point digital signal processing requiring extensive video I/O. Compare L2 memory size (512 KB vs. 256 KB in DM647) if larger on-chip buffer capacity is needed. Verify that the required peripheral set (e.g., dual SGMII ports) is available on the DM648 variant rather than the DM647.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320DM64x Digital Media Processor series, which combines C64x+ DSP cores with application-specific hardware logic. It is part of the TMS320C6000 platform, offering upward code compatibility with previous C64x devices. The DM648 variant specifically provides enhanced memory and connectivity compared to the DM647.

Digital Signal Processor Dsp Replacement Considerations

The TMS320DM647 is a related device within the same family but offers only 256 KB of L2 memory and one SGMII port. Other C64x+ processors may require significant architectural changes due to differences in peripheral sets and memory maps.
