Figure 21. Power Down/Up Mode AC Waveforms
Table 14. 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 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 7., page 21)
5. At 25°C (when using SOH28 + M4T28-BR12SH SNAPHAT top); VCC = 0V.
