SYMBOLS NO. PARAMETER MIN MAX UNITS Note: n: An automatic RECALL also takes place at power up, starting when VCC exceeds 3.8V, and taking tRECALL from the time at which VCC exceeds 4.5V. VCC must not drop below 3.8V once it has exceeded it for the RECALL to function properly. Note o: If E is low for any period of time in which W is high while G and NE are low, then a RECALL cycle may be initiated. Note p: Measured with W and NE both returned high, and G returned low. Note that STORE cycles are inhibited/aborted by VCC < 3.8V (STORE inhibit). Note q: Once tWC has been satisfied by NE, G, W and E, the STORE cycle is completed automatically. Any of NE, G, W or E may be used to terminate the STORE initiation cycle.
