TMS320DM647ZUT7

Digital Signal Processor Dsp Overview

The TMS320DM647ZUT7 is a fixed-point digital signal processor from the Texas Instruments DaVinci family, housed in a 529-ball Flip Chip Ball Grid Array (FCBGA) package. It integrates a C64x+ DSP core operating at up to 594 MHz and an ARM926EJ-S subsystem running at 297 MHz. The device features 248 KB of on-chip RAM and 8 KB of ROM. Key interfaces include Ethernet, USB, SPI, I2C, UART, McASP, and EBI/EMI. It supports video processing applications with integrated hardware accelerators for MPEG-4, H.264, and VC-1 codecs.

Digital Signal Processor Dsp Procurement Notes

Verify RoHS compliance status as older revisions may differ. Confirm lead time and availability as this component series has reached end-of-life stages in many regions. Ensure proper ESD handling during procurement and storage due to moisture sensitivity classification.

Digital Signal Processor Dsp Selection Notes

Select this model when high-performance video decoding is required alongside general-purpose control via the ARM core. Compare against the TMS320DM6467 if lower clock speeds are sufficient or if pin compatibility with existing designs is critical. Verify power supply requirements for 1.2V core and 1.8V/3.3V I/O domains.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320DM647x series of Digital Media Processors. It is designed for complex video processing tasks requiring both high-throughput DSP capabilities and efficient system management through the embedded ARM processor. It serves as a successor to earlier single-core DSP solutions in multimedia applications.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements are limited due to the specific dual-core configuration and FCBGA footprint. Consider the TMS320DM6467ZUTA for similar functionality but verify pinout and performance differences. Newer generations like the DM81xx series offer improved performance but require significant design changes.
