Substitute Part Grouping Explanation

Substitution eligibility for the DM6446ANB6C2127VC is determined by strict equivalence across the following critical parameters:

• Manufacturer and Series: Both parts must be from Texas Instruments' TMS320DM644x DaVinci™ series
• Type: Digital Media System-on-Chip (DMSoC) classification
• Processing Performance: Identical clock rates (594MHz DSP, 297MHz ARM®)
• Memory Configuration: Matching on-chip RAM (160kB) and ROM (8kB)
• Electrical Specifications: Identical core voltage (1.20V) and I/O voltage levels (1.8V, 3.3V)
• Thermal Range: Operating temperature 0°C ~ 85°C (TC)
• Package Compatibility: 361-LFBGA package with 361-NFBGA (16x16) supplier device package
• Interface Set: Complete ASP, EBI/EMI, Host Interface, I2C, SPI, UART, USB support
• Compliance: ROHS3 compliance and MSL 3 rating

The TMS320DM6446BZWT meets all these criteria and is identified as the manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

The TMS320DM6446BZWT is a direct functional equivalent to the DM6446ANB6C2127VC. Both devices share identical electrical, thermal, and mechanical specifications, as well as complete interface compatibility. The primary distinction is product lifecycle status: the DM6446ANB6C2127VC is in Last Time Buy phase, while the TMS320DM6446BZWT is marked Not For New Designs.

For existing designs currently using the DM6446ANB6C2127VC, the TMS320DM6446BZWT provides continuity during the transition period. Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring no changes to manufacturing or handling procedures are required.

For new design initiatives, alternative solutions outside the TMS320DM644x series should be evaluated, as both variants are subject to end-of-life constraints.

Frequently Asked Questions (FAQ)

Q: Can the TMS320DM6446BZWT be used as a direct replacement for the DM6446ANB6C2127VC?

A: Yes. The TMS320DM6446BZWT is electrically and mechanically equivalent. All electrical parameters, clock rates, memory configurations, interface sets, voltage specifications, and package dimensions are identical. No circuit modifications are required.

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

A: Last Time Buy indicates the manufacturer will accept final orders before discontinuation. Not For New Designs means the part is no longer recommended for new product development but remains available for existing applications. Both statuses indicate limited future availability.

Q: Are there any handling or storage differences between these parts?

A: No. Both parts have identical Moisture Sensitivity Level (MSL) ratings of 3 (168 Hours), requiring the same storage and handling protocols.

Q: Will the 361-NFBGA (16x16) package fit existing PCB layouts designed for the DM6446ANB6C2127VC?

A: Yes. Both parts use the identical 361-LFBGA package with 361-NFBGA (16x16) supplier device package specifications. PCB footprints, solder pad layouts, and assembly processes remain unchanged.

Q: Are both parts RoHS compliant?

A: Yes. Both the DM6446ANB6C2127VC and TMS320DM6446BZWT are ROHS3 compliant and REACH unaffected.
