Substitute Part Grouping Explanation

Substitution eligibility for the TMS320DM648ZUT9 is determined by strict equivalence across the following critical parameters:

• Clock Rate: 900MHz
• Type: Fixed Point
• On-Chip RAM: 576kB
• Non-Volatile Memory (ROM): 64kB
• Voltage - Core: 1.20V
• Voltage - I/O: 1.8V, 3.3V
• Operating Temperature Range: 0°C ~ 90°C (TC)
• Package / Case: 529-BFBGA
• Supplier Device Package: 529-FCBGA (19x19)
• Interface: Host Interface, I2C, McASP, PCI, SPI, UART
• Series: TMS320DM64x, DaVinci™

The TMS320DM648CUT9 meets all electrical, mechanical, and functional parameters required for direct substitution. The primary distinction is product status: the original part is obsolete, while the substitute is active.

Parameter Comparison

Engineering Selection Recommendations

Frequently Asked Questions (FAQ)

Q: Can the TMS320DM648CUT9 be used as a direct replacement for the TMS320DM648ZUT9?

A: Yes. Both parts share identical electrical specifications, memory configuration, clock rate, interface protocols, package type, and operating temperature range. No design modifications are required.

Q: Are there any differences in pin configuration or package dimensions?

A: No. Both parts use the 529-FCBGA (19x19) package with 529-BFBGA case designation. Pin configuration and mechanical dimensions are identical.

Q: What is the significance of the product status difference?

A: The TMS320DM648ZUT9 is obsolete, meaning Texas Instruments no longer manufactures or supports this part. The TMS320DM648CUT9 is active, ensuring continued availability and manufacturer support.

Q: Does the RoHS3 compliance of the substitute part affect compatibility?

A: No. RoHS3 compliance is a manufacturing and environmental standard that does not alter electrical or functional performance. The substitute part is fully compatible with designs originally specified for the obsolete part.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both parts have MSL 4 (72 Hours) rating, requiring identical handling and storage protocols.
