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 X25F087 is a CMOS 8k-bit SerialFlash, internally organized as 1024 x 8. The X25F087 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.

There are eight options for programmable, nonvolatile, Block Lock Protection available to the end user. These options are implemented via special instructions programmed to the part. The X25F087 also features a PP pin that can be used for hardwire protection of the part, disabling all programming attempts, as well as a Program Enable Latch that must be set before a program operation can be initiated.

The X25F087 utilizes Xicor's proprietary Direct WriteTM cell, providing a minimum endurance of 100,000 cycles per sector and a minimum data retention of 100 years.
