Figure 22. Power Down/Up Mode AC Waveforms
Table 10. Power Down/Up AC Characteristics
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
200s 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 16, page 32)
