â Stresses beyond those listed under âabsolute maximum ratingsâ 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 ârecommended operating conditionsâ is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values are with respect to VSS.
2. Actual operating power is less. This value was obtained under specially produced worst-case test conditions for the TMS320C31-33
and the TMS320LC31-33, which are not sustained during normal device operation. These conditions consist of continuous parallel
writes of a checkerboard pattern to both primary and extension buses at the maximum rate possible. See normal (ICC) current
specification in the electrical characteristics table and also read Calculation of TMS320C30 Power Dissipation Application Report
(literature number SPRA020).
