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 VSS fall time of less than tFB may cause corruption of RAM data.
3. tREC (min) = 20ms for industrial temperature grade (6) device.
