† 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.

‡ All voltage values are with respect to VSS.

§ Absolute dc input level should not exceed the DVDD or VSS supply rails by more than 0.3 V. An instantaneous low current pulse of < 2 ns,

< 10 mA, and < 1 V amplitude is permissable.

¶ Actual operating power is much lower. This value was obtained under specially produced worst-case test conditions for the SM/SMJ320VC33,

which are not sustained during normal device operation. These conditions consist of continuous parallel writes of a checkerboard pattern to the

external data and address buses at the maximum possible rate with a capacitive load of 30 pF. See normal (ICC) current specification in the

electrical characteristics table and also read TMS320C3x General-Purpose Applications (literature number SPRU194).

‡ All voltage values are with respect to VSS.

§ Absolute dc input level should not exceed the DVDD or VSS supply rails by more than 0.3 V. An instantaneous low current pulse of < 2 ns, < 10 mA,

and < 1 V amplitude is permissable.

# All inputs and I/O pins are configured as inputs.

|| All input and I/O pins use a Schmidt hysteresis inputs except SHZ and D0-D31. Hysteresis is approximately 10% of DVDD and is centered at

0.5 x DVDD.

kCVDD should not exceed DVDD by more than 0.7 V. (Use a Schottky clamp diode between these supplies.)

hDVDD should not exceed CVDD by more than 2.5 V.
