Substitute Part Grouping Explanation

Substitution eligibility for the TMS320F2812GHHS is determined by strict alignment of the following core parameters:

• Core processor architecture (C28x)
• Core size (32-Bit Single-Core)
• Operating frequency (150MHz)
• Program memory capacity (256KB FLASH)
• RAM capacity (18K x 16)
• Supply voltage range (1.81V ~ 2V)
• Data converter specification (A/D 16x12b)
• I/O count (56 pins)
• Connectivity interfaces (CANbus, EBI/EMI, McBSP, SCI, SPI, UART/USART)
• Peripheral set (DMA, POR, PWM, WDT)
• Automotive grade and AEC-Q100 qualification
• BGA package family (179-pin configuration)

The TMS320F2812ZAYA meets all substitution criteria as a direct functional equivalent, with differences limited to packaging variant and operating temperature range.

Engineering Selection Recommendations

The TMS320F2812ZAYA is a direct functional substitute for the TMS320F2812GHHS based on identical core specifications, memory configuration, and peripheral architecture. Both devices are classified as obsolete products from Texas Instruments.

Key considerations for selection:

• Operating temperature range: The TMS320F2812GHHS supports -40°C to 125°C, while the TMS320F2812ZAYA supports -40°C to 85°C. Applications requiring operation above 85°C must use the original part number.
• RoHS compliance: The TMS320F2812ZAYA meets ROHS3 compliance, whereas the TMS320F2812GHHS is non-compliant. For designs with RoHS requirements, the substitute part is preferred.
• Package variant: Both parts use 179-pin BGA packages with identical footprints (12x12mm). The MicroStar and NFBGA designations represent packaging process variants from Texas Instruments with no functional impact on electrical performance or pinout.
• Automotive qualification: Both parts maintain AEC-Q100 qualification and automotive-grade designation, suitable for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can TMS320F2812ZAYA replace TMS320F2812GHHS in all applications?

A: The TMS320F2812ZAYA is functionally equivalent for applications operating within -40°C to 85°C. Applications requiring operation above 85°C must use the original TMS320F2812GHHS or identify alternative solutions, as the substitute part is not rated for higher temperatures.

Q: What is the difference between 179-BGA MicroStar and 179-NFBGA packaging?

A: Both designations refer to 179-pin ball grid array packages in a 12x12mm footprint. MicroStar and NFBGA are Texas Instruments packaging process variants. The electrical performance, pinout, and PCB footprint are identical. Selection between variants depends on supplier availability and manufacturing process compatibility.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the TMS320F2812GHHS and TMS320F2812ZAYA carry automotive-grade designation and AEC-Q100 qualification, making them suitable for automotive applications within their respective operating temperature ranges.

Q: Why is RoHS compliance different between these parts?

A: The TMS320F2812GHHS predates RoHS3 compliance requirements and is marked as non-compliant. The TMS320F2812ZAYA is a later production variant meeting ROHS3 standards. For designs with environmental or regulatory RoHS requirements, the substitute part is preferred.

Q: Are there any pinout differences between these parts?

A: No. Both parts maintain identical pinout, I/O count (56), and connectivity interfaces. PCB designs are fully compatible without modification.

Q: What should be considered when sourcing these obsolete parts?

A: Both parts are classified as obsolete. Inventory availability is limited. The TMS320F2812GHHS has 18,560 units in stock, while TMS320F2812ZAYA has 3,300 units available. For long-term production requirements, contact Texas Instruments for end-of-life support options or identify next-generation C2000 C28x alternatives.
