AT25128/256
The AT25128/256 is capable of a 64-byte page write operation. After each byte of data
is received, the six-low order address bits are internally incremented by one; the high-
order bits of the address will remain constant. If more than 64 bytes of data are transmit-
ted, the address counter will roll over and the previously written data will be overwritten.
The AT25128/256 is automatically returned to the write disable state at the completion
of a write cycle.
NOTE: If the device is not Write enabled (WREN), the device will ignore the Write
instruction and will return to the standby state, when CS is brought high. A new CS fall-
ing edge is required to reinitiate the serial communication.
