Substitute Part Grouping Explanation

Substitution eligibility for the TMX320F28075PTPT is determined by strict equivalence across the following critical parameters:

• Core processor architecture (C28x)
• Core configuration (32-Bit Single-Core)
• Operating frequency (120MHz)
• Program memory capacity and type (512KB FLASH)
• RAM capacity (50K x 16)
• I/O count (97 pins)
• Supply voltage range (1.14V ~ 3.47V)
• Data converter specifications (A/D 17x12b; D/A 3x12b)
• Operating temperature range (-40°C ~ 105°C)
• Package type (176-LQFP Exposed Pad)
• Connectivity interfaces (CANbus, EBI/EMI, I2C, McBSP, SCI, SPI, UART/USART, USB)
• Peripheral set (DMA, POR, PWM, WDT)
• Environmental compliance (ROHS3 Compliant)

The TMS320F28075PTPT meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The TMS320F28075PTPT is a direct functional equivalent to the TMX320F28075PTPT. Both devices share identical electrical specifications, core architecture, memory configuration, I/O count, and package geometry. The primary distinction is product status: the TMX320F28075PTPT is obsolete, while the TMS320F28075PTPT is active and currently in production.

The TMS320F28075PTPT offers additional advantages for new designs and ongoing production:

• Active product status ensures continued availability and manufacturing support
• Functional Safety (FuSa) certification in the TMS320F28075PTPT series provides enhanced reliability documentation
• Improved moisture sensitivity level (MSL 3 vs. MSL 4) allows extended storage and handling windows
• ROHS3 compliance is maintained across both variants

For applications currently using the TMX320F28075PTPT, direct substitution with the TMS320F28075PTPT is electrically and mechanically compatible without design modification.

Frequently Asked Questions (FAQ)

Q: Can the TMS320F28075PTPT replace the TMX320F28075PTPT in existing designs?

A: Yes. The TMS320F28075PTPT is a direct substitute. Both devices are pin-compatible, electrically equivalent, and housed in the same 176-LQFP package. No PCB redesign or firmware modification is required.

Q: What is the difference between the TMX320F28075PTPT and TMS320F28075PTPT?

A: The devices are functionally identical in core processor, memory, I/O, and connectivity specifications. The TMS320F28075PTPT is the active production variant with Functional Safety (FuSa) certification, while the TMX320F28075PTPT is obsolete. The TMS320F28075PTPT also features improved moisture sensitivity handling (MSL 3 vs. MSL 4).

Q: Are there any package or pinout differences?

A: No. Both parts use the 176-LQFP Exposed Pad package with identical pinout and mechanical dimensions (24x24mm).

Q: What is the moisture sensitivity level difference, and does it affect substitution?

A: The TMX320F28075PTPT has MSL 4 (72-hour floor life), while the TMS320F28075PTPT has MSL 3 (168-hour floor life). The TMS320F28075PTPT provides a longer handling window before baking is required. This does not prevent substitution but offers improved manufacturing flexibility.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the TMX320F28075PTPT and TMS320F28075PTPT are ROHS3 compliant and meet environmental regulatory requirements.

Q: Can I use the TMS320F28075PTPT in safety-critical applications?

A: The TMS320F28075PTPT includes Functional Safety (FuSa) certification. Consult Texas Instruments documentation for specific safety qualification details and application requirements.
