TMS320DM648ZUT1

Digital Signal Processor Dsp Overview

The TMS320DM648ZUT1 is a digital media processor from the TMS320DM64x family, manufactured by Texas Instruments. It integrates a C64x+ DSP core operating at clock rates up to 800 MHz, delivering 6400 MIPS performance. The device features a 529-pin Flip Chip Plastic BGA (ZUT) package with dimensions of 19x19 mm and a 0.8 mm pitch. Key hardware specifications include 32KB L1 program cache, 32KB L1 data cache, and 512KB unified L2 mapped RAM/cache. Power requirements consist of a 1.2 V core voltage and 1.8 V/3.3 V I/O voltages.

• Peripheral Set: Includes five configurable video ports, 3-port Gigabit Ethernet Switch Subsystem, DDR2 SDRAM controller, EMIFA, McASP, SPI, I2C, UART, and PCI interface.
• Package: 529-pin nFBGA (ZUT suffix), 19x19 mm footprint, 0.09-μm CMOS process.

Digital Signal Processor Dsp Applications

• Digital Video Recording
• Video Conferencing Systems
• Network Video Surveillance

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix associated with the ZUT package to confirm the exact operational frequency (e.g., -720, -800, -900). Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure the ordering part number matches the required temperature range and production status.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring high-throughput digital signal processing with integrated video and networking capabilities. The DM648 variant provides double the L2 memory compared to the DM647. Ensure the design supports the required 1.2V core and 1.8V/3.3V I/O power domains. Verify that the 529-pin BGA layout constraints fit the target PCB design.

Digital Signal Processor Dsp Part Context

This device belongs to the TMS320C6000 DSP platform, specifically the DM64x Digital Media Processor series. It is designed as an upward code-compatible successor to previous C6000 devices, leveraging the advanced VelociTI architecture. The ZUT suffix denotes the specific 529-pin flip-chip ball grid array packaging used for this model.

Digital Signal Processor Dsp Replacement Considerations

The TMS320DM647 is a pin-compatible alternative within the same family but offers reduced L2 memory (256KB vs 512KB) and different supported clock speeds. Software compatibility is maintained due to shared C64x+ instruction sets, but memory allocation strategies must be adjusted accordingly.
