512 x 8 Bit

X25057

5MHz Low Power SPI Serial E²PROM with IDLock™ Memory

DESCRIPTION

FEATURES

TheX25057isaCMOS4K-bitserialE²PROM,internally

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.

• 5MHz Clock Rate

• IDLock™ Memory

—IDLock First or Last Page, Any 1/4 or Lower 1/2

of E²PROM Array

• Low Power CMOS

—<1µA Standby Current

—<3mA Active Current during Write

—<400µA Active Current during Read

• 1.8V to 3.6V, 2.7V-5.5V or 4.5V to 5.5V Operation

• Built-in Inadvertent Write Protection

—Power-Up/Power-Down Protection Circuitry

—Write Enable Latch

—Write Protect Pin

• SPI Modes (0,0 & 1,1)

• 512 x 8 Bits

—16 Byte Page Mode

• Self-Timed Write Cycle

—5ms Write Cycle Time (Typical)

• High Reliability

—Endurance: 100,000 Cycles/Byte

—Data Retention: 100Years

—ESD: 2000V on all pins

• 8-Lead MSOP Package

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

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.

The X25057 utilizes Xicor’s proprietary Direct Write^TM

cell, providing a minimum endurance of 100,000 cycles

per byte and a minimum data retention of 100 years.

• 8-Lead TSSOP Package

• 8-Lead SOIC Package

• 8-Lead PDIP Package
