TMS320DM6446AZWTA

Digital Signal Processor Dsp Overview

The TMS320DM6446AZWTA is a DaVinci Digital Media System-on-Chip manufactured by Texas Instruments. It integrates an ARM926EJ-S RISC core and a TMS320C64x+ DSP core within a 361-pin NFBGA package. The device supports maximum clock frequencies of 594 MHz for the ARM core and up to 810 MHz for the DSP core, operating at a 1.2 V supply voltage with 1.8 V/3.3 V I/O levels. Key on-chip resources include 16 kB data RAM, configurable L1/L2 caches, two video ports, an Ethernet MAC, USB, and UART interfaces.

Digital Signal Processor Dsp Feature Summary

• Dual-core architecture combining ARM926EJ-S and TMS320C64x+ DSP
• Integrated 10/100 Mb/s Ethernet MAC (EMAC) with MDIO
• Two configurable video ports for digital media processing
• Supports fixed-point DSP operations with up to 6480 MIPS performance

Digital Signal Processor Dsp Applications

• Network media encoding and decoding applications
• Embedded devices requiring robust OS support and rich user interfaces
• Digital video surveillance systems
• Portable multimedia players

Digital Signal Processor Dsp Procurement Notes

Verify component authenticity through authorized Texas Instruments distributors or certified partners. Confirm the specific suffix 'A' indicates the 594 MHz ARM / 810 MHz DSP speed grade variant. Check RoHS compliance documentation as required by regional regulations. Ensure ESD handling procedures are followed during procurement and storage.

Digital Signal Processor Dsp Selection Notes

Select this model when high-performance digital signal processing is required alongside general-purpose control via the ARM core. The 361-pin NFBGA package requires appropriate PCB layout considerations for thermal management and signal integrity. Verify that the target application utilizes the available memory map and peripheral interfaces, such as EMAC and video ports, effectively.

Digital Signal Processor Dsp Part Context

This part belongs to the TMS320DM6446 series within the DaVinci family. It shares the same core architecture and peripheral set as other variants like DM6446ANB6C2127VC, differing primarily in packaging, speed grades, and temperature ranges. The AZWTA designation specifically identifies the 361-pin NFBGA package with industrial/commercial temperature ratings.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacements may include other TMS320DM6446 variants with compatible packages, such as DM6446AZWT. Verify speed grade compatibility, as some variants operate at lower frequencies (e.g., 513 MHz). Ensure software drivers and hardware configurations support the specific peripheral capabilities of the substitute.
