Table 7. Power Down/Up Trip Points DC Characteristics (1)
(TA = 0 to 70 °C)
Note: 1. All voltages referenced to VSS.
2. At 25°C.
Table 8. Power Down/Up AC Characteristics
(TA = 0 to 70 °C)
Note: 1. VPFD (max) to VPFD (min) fall time of less than tF may result in deselection/write protection not occurring until 200ms after VCC pass-
es VPFD (min).
2. VPFD (min) to VSS fall time of less than tFB may cause corruption of RAM data.
