1. Typical values for nominal supply voltage. This parameter is only sampled, and is not 100% tested.

VIN = 0V

VOUT = 0V

Note:

1. The input timing reference is 0.8V for VIL and 2.0V for VIH.

2. tOE and tDFP are characteristics of the device, but must be accommodated by the programmer.

3. When programming the Atmel AT27LV040A, a 0.1µF capacitor is required across VPP and ground to suppress spurious

voltage transients.
