... Description The AT25P1024 provides 1,048,576 bits of serial electrically erasable programmable read only memory (EEPROM) organized as 131,072 words of 8 bits each. The device is optimized for use in many industrial and commercial applications where low power and low voltage operation are essential. The AT25P1024 is available in space saving 20-lead JEDEC SOIC and 8-lead LAP packages ...

... 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. The block write protection levels and corresponding status register control bits are shown in Table 8 ...
