Timing Conditions

Unless specified otherwise, the following conditions are true for all timing measurements. All characteristics are

specified at VDDIO = 3.1 - 3.5 V and VSS = 0 V over an operating temperature of -40Â°C to +85Â°C. Pin loadings is 50 pF.

The timing values are referenced to 1/2 VDD.
