† Clamp current stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress

ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating

conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

‡ Long-term high-temperature storage and/or extended use at maximum temperature conditions may result in a reduction of overall device life.

TMS320LF24x and TMS320F281x Devices Application Report (literature number SPRA963).

§ See the mechanical data package page for thermal resistance values, ΘJA (junction-to-ambient) and ΘJC (junction-to-case).

¶ VCCA should not exceed VDD by 0.3 V.

# For applications that involve millions of power cycles, it is recommended that VCCP be powered after VDD.
