Table 9. Power Down/Up AC Characteristics
Note: 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 200s after VCC pass-
es VPFD (min).
3. VPFD (min) to VSS fall time of less than tFB may cause corruption of RAM data.
Table 10. Power Down/Up Trip Points DC Characteristics
Note: 1. All voltages referenced to VSS.
2. 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).
3. Requires use of M4T32-BR12SH SNAPHAT top when using the SOH28 package.
