† 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 permissible.
¶ Actual operating power is much lower. This value was obtained under specially produced worst-case test conditions for the TMS320VC33, 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 User’s Guide (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 permissible.
# All inputs and I/O pins are configured as inputs.
|| All input and I/O pins use a Schmitt hysteresis inputs except SHZ and D0−D31. Hysteresis is approximately 10% of DVDD and is centered at
0.5 * 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.
