Figure 11. Power Up Timing

Table 6. Power Down/Up AC Characteristics

Note: 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.
