Substitute Part Grouping Explanation

Substitution of the TMS320F28332PTPQ is determined by strict equivalence across the following critical parameters:

• Core Architecture: C28x processor with identical instruction set compatibility
• Memory Configuration: 128KB FLASH (64K x 16) and 26K x 16 RAM
• Clock Speed: 100MHz operation
• Voltage Supply Range: 1.71V ~ 1.89V
• Package Type: 176-HLQFP (24x24) with exposed pad
• Connectivity Interfaces: CANbus, EBI/EMI, I2C, McBSP, SCI, SPI, UART/USART
• Peripheral Set: DMA, POR, PWM, WDT
• I/O Count: 88 pins
• Data Converter Specification: A/D 16x12b

The primary difference between the main part and its substitute lies in packaging configuration and product status. The TMS320F28332PTPS is the direct substitute, differing only in packaging type (Tray versus standard packaging) while maintaining identical electrical and functional specifications.

Parameter Comparison

Engineering Selection Recommendations

The TMS320F28332PTPS is the direct functional equivalent of the TMS320F28332PTPQ. Both parts maintain identical electrical specifications, memory configuration, processing capability, and peripheral functionality. The substitute part is currently in Active product status, whereas the original part is Obsolete, making the TMS320F28332PTPS the appropriate selection for new designs and ongoing production support.

Both parts carry AEC-Q100 automotive qualification and are ROHS3 compliant, meeting the same regulatory and environmental standards. The packaging difference (Tray versus standard) does not affect electrical or functional compatibility and is a supply chain consideration only.

Frequently Asked Questions (FAQ)

Q: Are the TMS320F28332PTPQ and TMS320F28332PTPS electrically identical?

A: Yes. Both parts share identical core processor architecture, clock speed, memory configuration, voltage supply range, I/O count, connectivity interfaces, and peripheral sets. All electrical and functional specifications are equivalent.

Q: What is the difference between these two part numbers?

A: The primary difference is product status and packaging configuration. The TMS320F28332PTPQ is Obsolete, while the TMS320F28332PTPS is Active. The TMS320F28332PTPS is supplied in Tray packaging, whereas the original part uses standard packaging. These differences do not affect electrical compatibility or functional performance.

Q: Can I use the TMS320F28332PTPS as a direct replacement in existing designs?

A: Yes. The TMS320F28332PTPS is a direct substitute with identical pin configuration, package dimensions (176-HLQFP 24x24), and electrical specifications. No design modifications are required.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the TMS320F28332PTPQ and TMS320F28332PTPS carry AEC-Q100 automotive qualification and are rated for -40°C to 125°C operating temperature.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN and HTSUS classifications. Moisture sensitivity level (MSL 4, 72 hours) is identical for both.

Q: Which part should I specify for new production?

A: The TMS320F28332PTPS should be specified for new production due to its Active product status. The TMS320F28332PTPQ is Obsolete and may face supply constraints.
