Substitute Part Grouping Explanation

Substitution of the TMS320DM6467ZUT7 is determined by strict equivalence across the following critical parameters:

• Processor Architecture: Identical DSP (729MHz) and ARM® (364.5MHz) core configurations
• Memory Configuration: Matching on-chip RAM (248kB) and ROM (8kB) capacity
• Power Supply Requirements: Identical core voltage (1.20V) and I/O voltage levels (1.8V, 3.3V)
• Interface Compatibility: Complete feature parity across all communication interfaces (Ethernet, USB, SPI, I2C, McASP, UART, HPI, EBI/EMI, PCI)
• Thermal Specifications: Operating temperature range 0°C ~ 85°C (TC)
• Package Compatibility: 529-BFBGA / 529-FCBGA (19x19) form factor for direct PCB substitution

The TMS320DM6467CCUT7 meets all these criteria and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The TMS320DM6467CCUT7 provides complete functional equivalence to the TMS320DM6467ZUT7 across all electrical, thermal, and interface specifications. Selection between these parts should be based on the following factors:

For Existing Systems: The TMS320DM6467ZUT7 remains suitable for maintenance and repair of deployed systems where component availability permits.

For New Designs: The TMS320DM6467CCUT7 is designated "Not For New Designs" by the manufacturer, indicating limited long-term availability. Both parts are classified as Obsolete or near-obsolete within the TMS320DM646x series. New design initiatives should evaluate alternative processor families from Texas Instruments' current product portfolio.

Compliance Considerations: The TMS320DM6467CCUT7 achieves ROHS3 compliance, whereas the TMS320DM6467ZUT7 is RoHS non-compliant. This distinction is relevant for applications subject to environmental regulations.

Moisture Sensitivity: The TMS320DM6467CCUT7 carries MSL rating 4 (72 hours), compared to MSL 2A (4 weeks) for the TMS320DM6467ZUT7. Storage and handling protocols must reflect the more stringent moisture sensitivity of the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the TMS320DM6467CCUT7 be used as a direct replacement for the TMS320DM6467ZUT7 in existing PCB designs?

A: Yes. Both parts share identical processor architecture, memory configuration, power supply requirements, operating temperature range, and package specifications (529-FCBGA 19x19). No PCB modifications are required for electrical or mechanical compatibility.

Q: Are there differences in interface functionality between these parts?

A: No. Both parts support the complete set of interfaces: EBI/EMI, Ethernet, HPI, I2C, McASP, PCI, SPI, UART, and USB. Interface behavior and electrical characteristics are identical.

Q: What is the significance of the different RoHS compliance statuses?

A: The TMS320DM6467CCUT7 meets ROHS3 requirements, while the TMS320DM6467ZUT7 does not. For applications subject to RoHS directives or customer specifications requiring RoHS compliance, the TMS320DM6467CCUT7 is the appropriate selection.

Q: How do the moisture sensitivity levels differ, and what does this mean for handling?

A: The TMS320DM6467ZUT7 has MSL 2A (4-week shelf life in controlled humidity), while the TMS320DM6467CCUT7 has MSL 4 (72-hour shelf life). The substitute part requires more stringent moisture control during storage and must be baked before reflow soldering if exposed to ambient humidity for extended periods.

Q: Why are both parts classified as Obsolete or Not For New Designs?

A: Both devices belong to the TMS320DM646x DaVinci™ series, which has reached end-of-life status within Texas Instruments' product roadmap. For new system development, alternative embedded processors from current product families should be evaluated.

Q: Are the clock rates and processing performance identical?

A: Yes. Both parts operate at 729MHz DSP and 364.5MHz ARM® clock rates with identical on-chip memory (248kB RAM, 8kB ROM), ensuring equivalent computational performance and real-time processing capability.
