Table 52A. Progr am, Write and Erase Times (5 V Range)
Note: 1. Programmed to all zero before erase.
2. The polling status, DQ7, is valid tQ7VQV time units before the data byte, DQ0-DQ7, is valid for reading.
3. If the maximum amount of time has elapsed between successive writes to an EEPR OM page, the transfer of this page data to EE-
PROM cells will begin. Also, bytes cannot be written to a page any faster than the indicated minimum time.
4. These specifications are for writing a page to EEPROM cells.
Table 52B. Program, Write and Erase Times (3 V Range)
Note: 1. Programmed to all zero before erase.
2. The polling status, DQ7, is valid tQ7VQV time units before the data byte, DQ0-DQ7, is valid for reading.
3. If this amount of time has elapsed between successive writes to an EEPR OM page, the transfer of this page data to EEPROM cells
will begin. Also, bytes cannot be written to a page any faster than the indicated minimum time.
