NOTES:

1.ICC Maximum is measured at worst case frequency, VCC, and temperature, with device operating and outputs loaded to the test conditions described in Section 4.7.1, “AC Test Conditions” on page 45.

2.ICC Typical is not tested.

3.Output Capacitance is the capacitive load of a floating output.

4.Measured with device operating and outputs loaded to the test conditions in Figure 8, “AC Test Load” on page 45. Input signals rise to VCC and fall to VSS.

5.ICC Active (Power Supply) value is provided for selecting your system’s power supply. It is measured using one of the worst case instruction mixes with VCC = 3.45 V. This parameter is characterized but not tested.

6.ICC Active (Thermal) value is provided for your system’s thermal management. Typical ICC is measured with VCC = 3.3 V and temperature = 25°C. This parameter is characterized but not tested.

7.ICC Test (Power modes) refers to the ICC values that are tested when the 80960HA/HD/HT is in Reset mode or ONCE mode with VCC = 3.45 V.

8.Worst case is VCC = 3.45 V, 0 °C.

9.ICC5 is tested at VCC = 3.0 V, VCC5 = 5.25 V.

10.Pin capacitance is characterized, but not tested.
