5MHz Low Power SPI Serial E2PROM with IDLock™ Memory  
DESCRIPTION  
FEATURES  
The X25057 is a CMOS 4K-bit serial E2PROM, internally  
organized as 512 x 8. The X25057 features a Serial  
•5MHz Clock Rate  
•IDLock™ Memory  
Peripheral Interface (SPI) and software protocol allowing  
operation on a simple four-wire bus. The bus  
—IDLock First or Last Page, Any 1/4 or Lower 1/2 of  
E2PROM Array  
•Low Power CMOS  
—<1∝A Standby Current  
signals are a clock input (SCK) plus separate data in (SI)  
and data out (SO) lines. Access to the device is  
—<3mA Active Current during Write —  
<400∝A Active Current during Read  
controlled through a chip select (CS) input, allowing any  
number of devices to share the same bus.  
•1.8V to 3.6V, 2.7V-5.5V or 4.5V to 5.5V Operation  
•Built-in Inadvertent Write Protection  
IDLock is a programmable 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  
—Power-Up/Power-Down Protection Circuitry —  
Write Enable Latch  
—Write Protect Pin  
•SPI Modes (0,0 & 1,1)  
•512 x 8 Bits  
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.  
—16 Byte Page Mode  
•Self-Timed Write Cycle  
The X25057 utilizes Xicor’s proprietary Direct WriteTM cell,  
providing a minimum endurance of 100,000 cycles  
—5ms Write Cycle Time (Typical)  
•High Reliability  
per byte and a minimum data retention of 100 years.  
—Endurance: 100,000 Cycles/Byte  
—Data Retention: 100 Years  
—ESD: 2000V on all pins
