DESCRIPTION
The X25057 is a CMOS 4K-bit serial E
organized as 512 x 8. The X25057 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.
2
PROM, internally
IDLock is a programmable locking mechanism which
allows the user to lock system ID and parametric data in
different portions of the E
ranging from as little as one page to as much as 1/2 of
the total array. The X25057 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.
2
PROM memory space,
The X25057 utilizes Xicor’s proprietary Direct Write
cell, providing a minimum endurance of 100,000 cycles
per byte and a minimum data retention of 100 years.
