Note: 1. Valid for Ambient Operating Temperature: TA = 0 to 70°C; VCC = 4.5 to 5.5V or 3.0 to 3.6V (except where noted).
2. These parameters are sampled with a 5 pF load and are not 100% tested.
3. tWP is specified as the logical AND of CE and WE. tWP is measured from the latter of CE or WE going low to the earlier of CE or
WE going high.
4. tWR is a function of the latter occurring edge of WE or CE.
5. tDH and tDS are measured from the earlier of CE or WE going high.
