Parameter Comparison

Engineering Selection Recommendations

The TMS320F28027PTS is a qualified direct substitute for the TMS320F280200PTS based on the following engineering criteria:

Electrical Compatibility: Both devices operate within identical voltage supply ranges (1.71V ~ 1.995V) and temperature specifications (-40°C ~ 125°C). Pin-to-pin compatibility is maintained through identical 48-LQFP packaging and I/O count (22 pins).

Architectural Compatibility: Both microcontrollers utilize the C28x core processor architecture and maintain identical peripheral configurations including I2C, SCI, SPI, UART/USART connectivity, along with Brown-out Detect/Reset, POR, PWM, and WDT functionality.

Compliance Status: The TMS320F28027PTS carries ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original part. The improved Moisture Sensitivity Level (MSL 2 vs. MSL 3) provides enhanced handling and storage characteristics.

Product Lifecycle: The TMS320F28027PTS maintains active product status with Texas Instruments, ensuring long-term availability and technical support compared to the obsolete TMS320F280200PTS.

Performance Enhancement: The substitute part provides increased processing speed (60MHz vs. 40MHz), expanded FLASH memory (64KB vs. 16KB), and increased RAM capacity (6K x 16 vs. 2K x 16), enabling support for more complex firmware implementations without architectural changes.

Frequently Asked Questions (FAQ)

Q: Can the TMS320F28027PTS be used as a direct replacement in existing TMS320F280200PTS designs?

A: Yes. The TMS320F28027PTS maintains identical pinout, package dimensions, voltage specifications, and peripheral configuration. No PCB modifications or schematic changes are required for direct substitution.

Q: Are there any firmware compatibility considerations?

A: The C28x core architecture is identical between both devices. Existing firmware compiled for the TMS320F280200PTS will execute on the TMS320F28027PTS. The increased memory capacity of the substitute part accommodates larger or more complex firmware implementations.

Q: What are the differences in memory specifications?

A: The TMS320F28027PTS provides 64KB FLASH program memory and 6K x 16 RAM compared to 16KB FLASH and 2K x 16 RAM in the TMS320F280200PTS. These enhancements allow for more extensive code and data storage without affecting electrical or mechanical compatibility.

Q: Does the speed difference (60MHz vs. 40MHz) affect system design?

A: The increased clock speed of the TMS320F28027PTS (60MHz) provides improved processing performance. Existing designs will operate correctly at the higher speed. System timing calculations and interrupt handling may benefit from the enhanced performance, but no design modifications are mandatory.

Q: What is the significance of the Moisture Sensitivity Level (MSL) difference?

A: The TMS320F28027PTS carries MSL 2 (1 Year) compared to MSL 3 (168 Hours) for the TMS320F280200PTS. This indicates improved moisture resistance and extended shelf life, reducing risk during component storage and handling.

Q: Is the TMS320F28027PTS available in the same packaging options?

A: Both devices are supplied in 48-LQFP (7x7) surface mount packages. The TMS320F28027PTS is available in Tray packaging, ensuring consistent handling and protection during distribution.

Q: What compliance certifications apply to the substitute part?

A: The TMS320F28027PTS is ROHS3 compliant and REACH unaffected, matching the regulatory requirements of the original TMS320F280200PTS. Both devices carry identical ECCN (3A991A2) and HTSUS (8542.31.0001) classifications.
