Note: 1. VPFD (max) to VPFD (min) fall time of less than tF may result in deselection/write protection not occurring until 200s after VCC pass-
es VPFD (min).
2. VPFD (min) to VSS fall time of less than tFB may cause corruption of RAM data.
3. At 25
°C (when using SOH28 + M4T28-BR12SH SNAPHAT top).
