Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMS320C6670AXCYP2 is determined by the following critical parameters:

• Manufacturer Series: Parts must belong to the TMS320C66x series to maintain architectural compatibility
• DSP Type: Fixed/floating-point processing capability must be preserved
• Clock Rate: 1.2 GHz operational frequency
• Memory Configuration: On-chip RAM (6.25 MB) and ROM (128 kB) specifications
• Voltage Specifications: Core voltage (1.00 V) and I/O voltage levels (1.0 V, 1.5 V, 1.8 V)
• Package Compatibility: 841-BFBGA FCBGA form factor with 24x24 dimensions
• Compliance Standards: ROHS3 compliance and REACH unaffected status

The substitute part TMS3TCI6618AXCYP2H is evaluated against these parameters to determine functional and physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TMS320C6670AXCYP2 is in Last Time Buy status, requiring transition planning. The substitute part TMS3TCI6618AXCYP2H is currently in Active product status, providing ongoing availability and support from Texas Instruments.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for new designs and production continuity. The substitute part's active status offers supply chain stability compared to the main part's end-of-life designation.

Selection between these parts should be based on specific application requirements regarding clock rate, memory configuration, and interface specifications, as detailed parameter alignment cannot be confirmed from available data for the substitute part.

Frequently Asked Questions (FAQ)

Q: Why is the TMS320C6670AXCYP2 being phased out? A: The part is designated as Last Time Buy, indicating Texas Instruments has concluded production and is transitioning customers to alternative solutions. This is standard practice for mature processor lines.

Q: What are the critical parameters for substitution? A: The TMS320C66x series designation, fixed/floating-point DSP architecture, 1.2 GHz clock rate, 6.25 MB on-chip RAM, 841-BFBGA package format, and voltage specifications (1.00 V core, 1.0/1.5/1.8 V I/O) are the primary determinants of functional compatibility.

Q: Are both parts RoHS and REACH compliant? A: Yes, both the TMS320C6670AXCYP2 and TMS3TCI6618AXCYP2H are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
