TMS320DM643AGNZ5

Digital Signal Processor Dsp Overview

The TMS320DM643AGNZ5 is a video and imaging fixed-point digital signal processor based on the C64x DSP core with VelociTI.2 extensions. It operates at clock rates of 500 MHz or 600 MHz, delivering up to 4800 MIPS. The device features a 64-bit external memory interface (EMIF), two configurable video ports, an Ethernet MAC, and a multichannel audio serial port. It utilizes a 1.4 V internal core voltage and 3.3 V I/O voltage. The component is housed in a 548-pin BGA package with a 1.0 mm ball pitch.

Digital Signal Processor Dsp Procurement Notes

Verify the suffix GNZ indicates big-endian mode and a 1.0 mm ball pitch BGA package. Confirm the specific speed grade (-500 or -600) required for the design. Check current production status as devices may be subject to obsolescence notices.

Digital Signal Processor Dsp Selection Notes

Select based on required clock frequency (500 MHz vs 600 MHz) and endianness requirements. Ensure the 1.0 mm pitch BGA package fits the PCB layout constraints. Verify power supply compatibility with 1.4 V core and 3.3 V I/O levels.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320DM643 family within the C6000 DSP platform. It shares architectural similarities with other DM64x devices but offers specific peripheral configurations tailored for video and imaging tasks. It is code-compatible with other C64x processors.

Digital Signal Processor Dsp Replacement Considerations

Consult Texas Instruments documentation for direct pin-to-pin or software-compatible alternatives within the C6000 family. Verify peripheral availability and package dimensions when considering substitutes.
