Note: 1. Valid for Ambient Operating Temperature: TA = –40 to 85°C; VCC = 4.5 to 5.5V or 2.7 to 3.6V (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.
4. Programmable (see Table 12., page 33)
