8.2 Page Write

A page write sequence allows up to 32 bytes to be written during the same write cycle, provided that all bytes are within the same row of the memory array. Partial page writes of fewer than 32 bytes are allowed. After each byte of data is received, the five lowest-order address bits are internally incremented. The higher-order address bits are not incremented and therefore retain the memory-array page location. If more bytes of data are transmitted than can fit within the current memory row, the address counter rolls over to the beginning of the same row. However, rollover events should be avoided as previously loaded data in the page may be unintentionally altered. The AT25080B/AT25160B automatically returns to the Write Disable state (WEL = 0) upon completion of a write cycle.
