TMS320DM8167BCYG2 Equivalent & Substitute Parts

Part Overview

The TMS320DM8167BCYG2 is a Digital Media System-on-Chip (DMSoC) from Texas Instruments' DM81x Video SOC DaVinci™ series, designed for embedded video processing applications. This part is classified as obsolete, making identification of compatible substitutes essential for ongoing system support, maintenance, and new design considerations where legacy compatibility is required.

The primary reason for identifying substitute parts is the obsolete product status, which affects long-term availability and supply chain continuity. Organizations maintaining systems based on this processor require validated alternatives to ensure operational continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the TMS320DM8167BCYG2 is determined by strict equivalence across the following critical parameters:

• Package / Case: Must be 1031-BFBGA, FCBGA (25x25) for mechanical and electrical compatibility
• Clock Rate: Must maintain 1GHz DSP and 1.2GHz ARM® specifications
• On-Chip RAM: Must provide 1.5MB capacity
• Non-Volatile Memory: Must include ROM (48kB)
• Voltage Specifications: Core voltage 1.00V; I/O voltages 1.5V, 1.8V, 3.3V
• Operating Temperature Range: 0°C ~ 95°C (TJ)
• Interface Set: Must support EBI/EMI, Ethernet, I2C, McASP, McBSP, PCI, Serial ATA, SD/SDIO, SPI, UART, USB
• Mounting Type: Surface Mount
• RoHS and Compliance: ROHS3 Compliant, REACH Unaffected

The TMS320DM8167SCYG2 qualifies as a direct substitute based on complete parameter alignment across all specified criteria.

Engineering Selection Recommendations

The TMS320DM8167SCYG2 is the qualified substitute for the TMS320DM8167BCYG2. Selection rationale is based on the following engineering factors:

Product Status: The TMS320DM8167SCYG2 maintains Active product status, ensuring ongoing manufacturer support, availability, and compliance updates. The original part's Obsolete classification necessitates transition to an actively supported alternative.

Compliance and Certifications: Both parts maintain identical ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for new designs and system upgrades.

Electrical and Mechanical Equivalence: Complete parameter alignment across core voltage, I/O voltage specifications, clock rates, memory configuration, interface set, and thermal operating range ensures functional interchangeability at the system level.

Packaging: Identical 1031-FCBGA (25x25) package specifications ensure direct PCB compatibility without layout modifications.

The primary differentiator is packaging format: the original part is supplied in standard packaging, while the substitute is supplied in Tray packaging. This distinction affects handling and storage procedures but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the TMS320DM8167SCYG2 be used as a direct replacement for the TMS320DM8167BCYG2 in existing designs?

A: Yes. The TMS320DM8167SCYG2 is electrically and mechanically equivalent across all specified parameters. No circuit modifications, firmware changes, or PCB layout adjustments are required for substitution.

Q: What is the difference between the BCYG2 and SCYG2 designations?

A: The letter designation in the part number indicates packaging format. The BCYG2 uses standard packaging, while the SCYG2 uses Tray packaging. The core silicon and electrical specifications are identical.

Q: Why is the original part classified as Obsolete?

A: Product obsolescence reflects Texas Instruments' end-of-life determination for this device. The DM81x Video SOC series has been superseded by newer processor generations. The TMS320DM8167SCYG2 remains in Active status and is the recommended path for ongoing system support.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts operate within the identical temperature range (0°C ~ 95°C TJ) and maintain identical clock rates (1GHz DSP, 1.2GHz ARM®). Thermal and performance characteristics are equivalent.

Q: What packaging considerations apply to the Tray format?

A: Tray packaging requires standard moisture control procedures consistent with MSL 4 (72 Hours) classification. Storage, handling, and reflow processes remain unchanged from the original part's requirements.

Q: Are compliance certifications identical between these parts?

A: Yes. Both parts maintain ROHS3 compliance and REACH Unaffected status. No additional compliance documentation or testing is required for substitution.

Q: What is the inventory status for the substitute part?

A: The TMS320DM8167SCYG2 has 2064 pieces in stock as new original inventory, providing supply continuity for design transitions and system maintenance.
