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.
NOTES:
1. All voltage values are with respect to VSS.
2. This value calculated for the ’C32-40. Actual operating power is less. This value was obtained under specially produced worst-case
test conditions which are not sustained during normal device operation. These conditions consist of continuous parallel writes of
a checkerboard pattern to the external bus at the maximum rate possible. See normal (IDD) current specification in the electrical
characteristics table and see the
Calculation of TMS320C30 Power Dissipation Application Report (literature number SPRA020).
