AC CHARACTERISTICS
Read-Only Operations – S29PL127H
Notes:
1. Not 100% tested.
3. Measurements performed by placing a 50 ohm termination on the data pin with a bias of VCC/2. The time from OE# high to
the data bus driven to VCC/2 is taken as tDF.
Read-Only Operations –S29PL129H
Notes:
1. Not 100% tested.
3. Valid CE1#/CE2# conditions: (CE1#= VIL, CE2#= VIH) or (CE1#= VIH, CE2#=VIL).
4. Valid CE1#/CE2# transitions: (CE1#= CE2#= VIH) to (CE1#= VIL, CE2#=VIH) or (CE1#= VIH, CE2#=VIL).
5. Measurements performed by placing a 50 ohm termination on the data pin with a bias of VCC/2. The time from OE# high to the data bus
driven to VCC/2 is taken as tDF.
6. Valid CE1#/CE2# transitions: (CE1#= VIL, CE2#= VIH) or (CE1#= VIH, CE2#=VIL) to (CE1#= CE2#= VIH).
