DESCRIPTION

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.
