1. Valid for ambient operating temperature: TA = –40 to 85°C; VCC = 2.7 to 3.6V or 4.5 to 5.5V(except where noted).
2. VPFD (max) to VPFD (min) fall time of less than tF may result in deselection/write protection not occurring until 200 µs after
VCC passes VPFD (min).
3. VPFD (min) to VSS fall time of less than tFB may cause corruption of RAM data.
