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 Write^TMcell,

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
