Note: All voltages referenced to VSS.
Note: At 25
°C.
Table 13. Power Down/Up AC Characteristics
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.
