TMS320DM642AGNZ6

Digital Signal Processor Dsp Overview

The TMS320DM642AGNZ6 is a video and imaging fixed-point digital signal processor based on the C64x DSP core. It operates at clock rates of 500, 600, or 720 MHz, delivering up to 5760 MIPS. The device features VelociTI.2 extensions for advanced VLIW processing, supporting quad 8-bit and dual 16-bit arithmetic per cycle. It includes 16 KB L1P cache, 16 KB L1D cache, and 256 KB L2 unified RAM/cache. Key peripherals include three configurable video ports, a 10/100 Mb/s Ethernet MAC, McASP, I2C, McBSP, PCI, and EMIF. The AGNZ6 suffix indicates a 1.4-V internal core voltage and big-endian support, housed in a 548-pin BGA package.

• Network video surveillance

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade (-500, -600, or -720) required for the application timing constraints. Confirm that the 1.4-V core voltage requirement aligns with the power delivery design. Ensure the 548-pin BGA footprint matches the PCB layout, noting the 1.0-mm ball pitch associated with the ZNZ suffix.

Digital Signal Processor Dsp Selection Notes

Select this component for applications requiring high-performance fixed-point video processing with integrated networking capabilities. The GNZ/ZNZ suffix variants are necessary if big-endian operation is required. Compare against other DM64x devices if different peripheral sets or memory configurations are needed.

Digital Signal Processor Dsp Part Context

The TMS320DM642 belongs to the TMS320C6000 DSP platform, specifically the C64x generation. It is code-compatible with other C64x devices but offers specialized multimedia peripherals like video ports and Ethernet MACs not found in standard C64x processors.

Digital Signal Processor Dsp Replacement Considerations

Check for updated versions within the DM64x family such as the TMS320DM643 series for enhanced performance or additional interfaces. Verify pin compatibility and software migration requirements when considering alternatives.
