TMS320DM642AZNZ5

Digital Signal Processor Dsp Overview

The TMS320DM642AZNZ5 is a video and imaging fixed-point digital signal processor from Texas Instruments, 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 quad 8-bit and dual 16-bit parallel processing. It includes three configurable video ports, a 10/100 Mb/s Ethernet MAC, and an EMIF supporting up to 1 GByte of external memory. The AZ suffix indicates a 1.4 V internal core voltage with 3.3 V I/O. It is housed in a 548-pin BGA package with a 1.0 mm ball pitch.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade (500, 600, or 720 MHz) required for the design, as the base part number covers multiple variants. Confirm that the 1.4 V core voltage requirement aligns with the power delivery network. Ensure the 548-pin BGA footprint matches the PCB layout, specifically noting the 1.0 mm ball pitch associated with the ZNZ suffix.

Digital Signal Processor Dsp Selection Notes

Select this component for high-performance digital media processing requiring significant parallel arithmetic throughput. The inclusion of dedicated video ports and Ethernet MAC reduces external component count for video surveillance or communication devices. Consider the 1.4 V core voltage if lower power consumption than the standard 1.2 V variant is acceptable or if specific board constraints apply.

Digital Signal Processor Dsp Part Context

This device belongs to the TMS320DM64x family within the C6000 DSP platform. It is code-compatible with other C64x processors but adds specialized peripherals for video and imaging. The AZNZ5 suffix denotes the 1.4 V core voltage, ZNZ package type (548-pin BGA, 1.0 mm pitch), and potentially temperature or revision specifications defined by TI.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the same family include the TMS320DM641 or TMS320DM643 series, provided pin compatibility and peripheral requirements match. Verify that alternative models support the necessary video port configurations and memory interfaces for the existing design.
