Electrical Specifications
This section provides the absolute maximum ratings and the recommended operating conditions for the
TMS320F281x and TMS320C281x DSPs.
6.1
Absolute Maximum Ratings
Unless otherwise noted, the list of absolute maximum ratings are specified over operating temperature
ranges. 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 Section 6.2 is not implied. Exposure to absolute-maximum-rated
conditions for extended periods may affect device reliability. All voltage values are with respect to V
