(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) All voltage values are with respect to VSS.
(3) 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.
(4) Actual operating power is much lower. This value was obtained under specially produced worst-case test conditions for the SMx320VC33, 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 (I
CC) current specification in
Electrical Characteristics and also read
TMS320C3x General-Purpose Applications (

(1) All voltage values are with respect to VSS.
(2) 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.
(3) All inputs and I/O pins are configured as inputs.
(4) All input and I/O pins use a Schmidt hysteresis inputs except SHZ and D0 to D31. Hysteresis is approximately 10% of DVDD and is centered at 0.5 × DVDD.
(5) CVDD should not exceed DVDD by more than 0.7 V. (Use a Schottky clamp diode between these supplies.)
(6) DVDD should not exceed CVDD by more than 2.5 V.

(6) Pins D0 to D31 include internal bus keepers that maintain valid logic levels when the bus is not driven (see
Figure 30).
(7) Actual operating current is less than this maximum value. 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 at the maximum rate possible. See

(2) Duty cycle is defined as 100 × t1 / (t1 + t2)%
(3) To ensure clean internal clock references, the minimal low and high pulse durations must be maintained. At high frequencies, this may require a fast rise and fall time as well as a tightly controlled duty cycle. At lower frequencies, these requirements are less restrictive when in x1 and x0.5 modes. The PLL, however, must have an input duty cycle of between 40% and 60% for proper operation.

However, if a pipeline conflict prevents the store from executing, the address of the store will not be driven until the store can execute.
