Substitute Part Grouping Explanation

Substitution eligibility for the TMS320F28PLC83PNT is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Identical core processor architecture (C28x)
• Matching core size (32-Bit Single-Core)
• Identical operating frequency (90MHz)
• Identical program memory capacity (256KB FLASH)
• Identical RAM capacity (50K x 16)
• Identical package type and pin count (80-LQFP with 12x12 footprint)
• Compatible supply voltage range (minimum overlap required)
• Identical mounting type (Surface Mount)
• Matching temperature operating range (-40°C ~ 105°C)

The TMS320F28069PNT meets these substitution criteria with the following considerations: it maintains identical core architecture, memory configuration, package form factor, and thermal specifications. Differences in connectivity options and data converter specifications do not preclude substitution when these parameters are not critical to the application.

Parameter Comparison

Engineering Selection Recommendations

The TMS320F28069PNT is a direct functional substitute for the TMS320F28PLC83PNT based on core architecture, memory configuration, package compatibility, and thermal specifications. The primary distinction is product status: the TMS320F28PLC83PNT is designated "Not For New Designs," while the TMS320F28069PNT carries "Active" status, making it the preferred selection for ongoing production and new applications.

Both devices maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications. The supply voltage range of the substitute part (1.71V ~ 1.995V) is narrower than the main part (1.71V ~ 3.63V); applications requiring operation above 1.995V must retain the original TMS320F28PLC83PNT or conduct voltage compatibility assessment.

Frequently Asked Questions (FAQ)

Q: Can the TMS320F28069PNT replace the TMS320F28PLC83PNT in existing designs?

A: Yes, provided the application supply voltage does not exceed 1.995V. The substitute maintains identical core processor, memory capacity, package form factor, pin count, and thermal operating range. Verify connectivity and data converter requirements against your application specifications.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates Texas Instruments has transitioned the TMS320F28PLC83PNT to end-of-life status. The TMS320F28069PNT, with "Active" status, represents the current production equivalent and is recommended for all new development.

Q: Are the 80-LQFP packages physically and electrically identical?

A: Both devices use the 80-LQFP (12x12) package with identical pin count and footprint. Surface mount assembly processes are compatible between the two parts.

Q: What are the differences in connectivity options?

A: The TMS320F28069PNT includes CANbus connectivity in addition to I2C, McBSP, SCI, SPI, and UART/USART. The main part TMS320F28PLC83PNT does not include CANbus. If CANbus functionality is not required, this difference does not affect substitution eligibility.

Q: How do the data converter specifications differ?

A: The TMS320F28PLC83PNT features A/D 4x12b configuration, while the TMS320F28069PNT provides A/D 12x12b. Applications dependent on specific analog-to-digital converter channel count must evaluate this difference against functional requirements.

Q: Are moisture sensitivity and handling requirements identical?

A: Both devices carry MSL 3 (168 Hours) rating. Identical moisture control and storage protocols apply to both parts.
