Notes:
1. For recommended operating conditions, see Table 3
2. System/board must be designed to ensure the input requirement to the device is achieved. Proper device operation is
guaranteed for inputs meeting this requirement by design, simulation, characterization, or functional testing.
3.13 Integrated flash controller
This section describes the DC and AC electrical specifications for the integrated flash
controller.
3.13.1 Integrated flash controller DC electrical characteristics
This table provides the DC electrical characteristics for the integrated flash controller
when operating at OVDD= 1.8 V.

1. The min VILand max VIH values are based on the respective min and max OVIN values found in Table 3.
2. The symbol VIN, in this case, represents the OVIN symbol referenced in Recommended operating conditions.
3. For recommended operating conditions, see Table 3.
