Key Parameters

Substitute Part Grouping Explanation

The TMS320F28026DAS qualifies as a direct substitute based on identical electrical and mechanical parameters across all critical specifications. Substitution is valid when the following parameters match:

• Core processor architecture (C28x)
• Core size (32-Bit Single-Core)
• Operating frequency (60MHz)
• Program memory capacity and type (32KB FLASH)
• RAM configuration (6K x 16)
• Supply voltage range (1.71V ~ 1.995V)
• Peripheral set (I2C, SCI, SPI, UART/USART, Brown-out Detect/Reset, POR, PWM, WDT)
• I/O count (20)
• Package type and dimensions (38-TSSOP)

The substitute part differs only in product status (Active vs. Obsolete), packaging format (Tray vs. standard), and maximum operating temperature specification.

Parameter Comparison

Engineering Selection Recommendations

The TMS320F28026DAS is a qualified substitute for the TMS320F28026DATR based on complete electrical and mechanical equivalence. Selection of the substitute part is supported by:

• Identical core architecture, memory configuration, and peripheral set
• Matching supply voltage specifications and I/O characteristics
• Identical package type and physical dimensions enabling direct PCB compatibility
• ROHS3 compliance and REACH unaffected status maintained
• Active product status ensuring continued availability and supply chain support
• Extended maximum operating temperature range (-40°C to 125°C vs. -40°C to 105°C) providing additional thermal margin

The substitute part is suitable for direct replacement in applications where the TMS320F28026DATR is specified, with no design modifications required.

Frequently Asked Questions (FAQ)

Q: Can TMS320F28026DAS replace TMS320F28026DATR in existing designs?

A: Yes. The TMS320F28026DAS provides complete functional and electrical equivalence. All core specifications, memory configuration, peripheral interfaces, and package dimensions are identical. Direct PCB substitution is possible without design changes.

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

A: The primary differences are product status (Obsolete vs. Active), packaging format (standard vs. Tray), and maximum operating temperature specification (105°C vs. 125°C). All electrical and mechanical parameters are identical.

Q: Are there any compatibility concerns with the 38-TSSOP package?

A: No. Both parts use identical 38-TSSOP packaging with matching physical dimensions (0.240", 6.10mm Width). Pin configuration and footprint are equivalent, enabling direct PCB-level substitution.

Q: Does the extended temperature range of TMS320F28026DAS affect compatibility?

A: No. The extended maximum operating temperature (125°C vs. 105°C) represents an expanded operational envelope. Applications designed for the TMS320F28026DATR operate within the TMS320F28026DAS specification range.

Q: Are compliance certifications maintained with the substitute part?

A: Yes. Both parts maintain ROHS3 compliance and REACH unaffected status. Moisture sensitivity level (MSL 2, 1 Year) is identical.

Q: What is the significance of the Active product status for TMS320F28026DAS?

A: Active product status indicates ongoing manufacturing and supply chain availability. This ensures long-term component sourcing for production and maintenance applications, addressing the obsolescence of the TMS320F28026DATR.
