DESCRIPTION
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 Write
cell, providing a minimum endurance of 100,000 cycles
per sector and a minimum data retention of 100 years.
