4 Peripheral and Electrical Specifications

4.1 Electrical Specifications

This section provides the absolute maximum ratings and the recommended operating conditions for the TMS320C672x DSP.

All electrical and switching characteristics in this data manual are valid over the recommended operating conditions unless otherwise specified.

4.2 Absolute Maximum Ratings(1) (2)

(1)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 conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)All voltage values are with referenced to VSS unless otherwise specified.

(3)If OSCVDD and OSCVSS pins are used as filter pins for reduced oscillator jitter, they should not be connected to CVDD and VSS externally.

4.3 Recommended Operating Conditions(1)
