TNETV6446AINZWT Equivalent & Substitute Parts

Part Overview

The TNETV6446AINZWT is a Digital Media System-on-Chip (DMSoC) from Texas Instruments' TMS320DM644x DaVinci™ series, designed for embedded video and multimedia processing applications. This device integrates a 594MHz DSP core with a 297MHz ARM® processor, supporting multiple interface protocols including ASP, EBI/EMI, Host Interface, I2C, SPI, UART, and USB.

The TNETV6446AINZWT carries a Last Time Buy product status, indicating that Texas Instruments has discontinued this part number and will no longer accept new orders after a specified date. This status necessitates identification of equivalent substitute components to maintain design continuity and ensure long-term supply chain reliability for existing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNETV6446AINZWT is determined by strict equivalence across the following critical parameters:

• Series and architecture compatibility (TMS320DM644x DaVinci™ family)
• Identical processor configuration (594MHz DSP, 297MHz ARM®)
• Matching memory specifications (160kB on-chip RAM, 8kB ROM)
• Identical package and pinout (361-LFBGA, 361-NFBGA 16x16)
• Equivalent voltage requirements (1.20V core, 1.8V/3.3V I/O)
• Identical interface support (ASP, EBI/EMI, Host Interface, I2C, SPI, UART, USB)
• Matching thermal and compliance specifications (0°C ~ 85°C, ROHS3, MSL 3)

The substitute part TMS320DM6446BZWT meets all these criteria and is therefore electrically and mechanically interchangeable with the TNETV6446AINZWT.

Parameter Comparison

Engineering Selection Recommendations

The TMS320DM6446BZWT is the direct substitute for the TNETV6446AINZWT based on complete electrical and mechanical equivalence. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The primary distinction between these parts is product status: the TNETV6446AINZWT is designated Last Time Buy, while the TMS320DM6446BZWT is marked Not For New Designs. This status difference reflects Texas Instruments' lifecycle management but does not affect functional compatibility or performance characteristics.

For applications currently using the TNETV6446AINZWT, the TMS320DM6446BZWT provides full drop-in replacement capability without design modifications, PCB layout changes, or firmware adjustments. Both parts share identical pinout, electrical specifications, and interface protocols.

Frequently Asked Questions (FAQ)

Q: Can the TMS320DM6446BZWT be used as a direct replacement for the TNETV6446AINZWT?

A: Yes. The TMS320DM6446BZWT is electrically and mechanically equivalent to the TNETV6446AINZWT. All critical parameters including processor configuration, memory specifications, voltage requirements, package type, and interface protocols are identical. No design changes are required.

Q: What is the difference between Last Time Buy and Not For New Designs status?

A: Last Time Buy indicates that the TNETV6446AINZWT will no longer be manufactured after a specified date, and existing inventory will be depleted. Not For New Designs indicates that the TMS320DM6446BZWT is no longer recommended for new product development but remains available for existing applications. Both statuses reflect end-of-life management rather than functional differences.

Q: Are the packages identical between these two parts?

A: Yes. Both parts use the 361-LFBGA package with 361-NFBGA (16x16) supplier device package designation. Pinout, ball layout, and mechanical dimensions are identical.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both the TNETV6446AINZWT and TMS320DM6446BZWT are ROHS3 compliant, REACH unaffected, and share identical ECCN and HTSUS classifications.

Q: Are there any performance differences between these parts?

A: No. Both parts feature identical clock rates (594MHz DSP, 297MHz ARM®), memory configurations (160kB on-chip RAM, 8kB ROM), voltage specifications, and operating temperature ranges.
