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 200µs after VCC pass-

es VPFD (min).

2. VPFD (min) to VSO fall time of less than tFB may cause corruption of RAM data.
