TMS320DM640AZDKA4

Digital Signal Processor Dsp Overview

The TMS320DM640AZDKA4 is a video and imaging fixed-point digital signal processor from the Texas Instruments TMS320DM64x family. It integrates a C64x DSP core operating at a maximum clock frequency of 600 MHz with 128 KB of L2 cache memory. The device features two 8-bit video ports, an Ethernet MAC, and multiple serial communication interfaces including McASP, McBSP, I2C, and EMIF. Designed for high-performance media processing, it supports SD and HD video applications within a specified operating temperature range.

Digital Signal Processor Dsp Feature Summary

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'ZDKA4' against the manufacturer's official documentation to confirm package type, pin count, and thermal rating. Ensure the component meets RoHS compliance requirements for the intended manufacturing process. Confirm that the silicon revision matches the design specifications.

Digital Signal Processor Dsp Selection Notes

Select this model when a 600 MHz C64x core speed is required alongside integrated video and Ethernet peripherals. Compare against the TMS320DM641 if additional audio or serial interfaces are needed. Verify power supply sequencing requirements for the 1.2V core and 3.3V I/O domains during system design.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320DM64x series, which combines a C64x DSP with ARM9 or peripheral sets for digital media processing. The DM640 variant specifically offers dual video ports and an Ethernet MAC, distinguishing it from lower-speed models like the DM640A or higher-end variants in the DaVinci family.

Digital Signal Processor Dsp Replacement Considerations

The TMS320DM641AZDKA4 is a compatible alternative within the same datasheet (SPRS222F), offering similar architecture but potentially different peripheral configurations such as additional McBSP channels.
