The X24325 features a serial interface and software protocol allowing opera- tion on a simple two wire bus. Three device select inputs (S0, S1, S2) allow up to eight devices to share a common two wire bus. A Write Protect Register at the highest address loca- tion, FFFh, provides three new write protection features: Software Write Protect, Block Write Protect, and Hardware Write Protect. The Software Write Protect feature prevents any nonvolatile writes to the X24325 until the WEL bit in the write protect register is set. The Block Write Protection feature allows the user to individually write protect four blocks of the array by programming two bits in the write protect register. The Programmable Hardware Write Protect feature allows the user to install the X24325 with WP tied to VCC, program the entire memory array in place, and then enable the hardware write protection by programming a WPEN bit in the write protect register. After this, selected blocks of the array, including the write protect register itself, are permanently write protected. Xicor E2PROMs are designed and tested for applica- tions requiring extended endurance. Inherent data retention is greater than 100 years.
