... Suspends Serial Input NC No Connect The AT25P1024 is enabled through the Chip Select pin (CS) and accessed via a 3- wire interface consisting of Serial Data Input (SI), Serial Data Output (SO), and Serial Clock (SCK). All programming cycles are completely self-timed, and no separate erase cycle is required before write. ...

... The AT25P1024 is designed to interface directly with the synchronous serial peripheral interface (SPI) of the 6800 type series of microcontrollers. The AT25P1024 utilizes an 8-bit instruction register. The list of instructions and their operation codes are contained in Table 5. All instructions, addresses, and data are transferred with the MSB first and start with a high-to-low transition. ...

... Bits 0-7 are “1”s during an internal write cycle. WRITE STATUS REGISTER (WRSR): The WRSR instruction allows the user to select one of four levels of protection. The AT25P1024 is divided into four array segments. Top quarter (1/4), top half (1/2), or all of the memory segments can be protected. Any of the data within any selected segment will therefore be read only ...

... If more than 128 bytes of data are transmitted, the address counter will roll over and the previously written data will be overwritten. The AT25P1024 is automat- ically returned to the write disable state at the completion of a write cycle. ...
