Table 3. Memory AC Characteristics, M48T251Y
Note: 1. Valid for Ambient Operating Temperature: T
A
= 0 to 70°C; V
CC
= 4.5 to 5.5V or 3.0 to 3.6V (except where noted).
2. These parameters are sampled with a 5 pF load are not 100% tested.
3. t
WP
is specified as the logical AND of CE and WE. t
WP
is measured from the latter of CE or WE going low to the earlier of CE or
WE going high.
4. t
DH
and t
DS
are measured from the earlier of CE or WE going high.
