1. Valid for ambient operating temperature: TA = 0 to 70°C; VCC = 4.75 to 5.5V 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 200µs after

VCC passes VPFD (min).

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