Serial Interface Description MASTER: The device that generates the serial clock. SLAVE: Because the Serial Clock pin (SCK) is always an input, the AT25080A/160A/320A/640A always operates as a slave. TRANSMITTER/RECEIVER: The AT25080A/160A/320A/640A has separate pins designated for data transmission ...

... WRITE STATUS REGISTER (WRSR): The WRSR instruction allows the user to select one of four levels of protection. The AT25080A/160A/320A/640A is divided into four array segments. One-quarter, one-half, or all of the memory segments can be protected. Any of the data within any selected segment will therefore be read only. The block write protection levels and corre- ...

... WRITE SEQUENCE (WRITE): In order to program the AT25080A/160A/320A/640A, two sepa- rate instructions must be executed. First, the device must be write enabled via the WREN instruction. Then a write (WRITE) instruction may be executed. Also, the address of the memory location( programmed must be outside the protected address field location selected by the block write protection level ...
