Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.This is a stress rating only and the functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The X25097 is a CMOS 8K-bit serial E²PROM, internally organized as 1024 x 8. The X25097 features a Serial Peripheral Interface (SPI) and software protocol allowing operation on a simple four-wire bus. The bus signals are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a chip select (CS) input, allowing any number of devices to share the same bus.

IDLock is a programmble locking mechanism which allows the user to lock system ID and parametric data in different portions of the E²PROM memory space,ranging from as little as one page to as much as 1/2 of the total array. The X25097 also features a WP pin that can be used for hardwire protection of the part, disabling all write attempts, as well as a Write Enable Latch that must be set before a write operation can be initiated.

The X25097 utilizes Xicor's proprietary Direct WriteTM cell, providing a minimum endurance of 100,000 cycles per byte and a minimum data retention of 100 years.
