SPI Serial E²PROM with Block Lock^TMProtection

FEATURES

DESCRIPTION

The X25040 is a CMOS 4096-bit serial E²PROM, internally

organized as 512 x 8. The X25040 features a Serial

•1MHz Clock Rate

•SPI Modes (0,0 & 1,1)

•512 X 8 Bits

—4 Byte Page Mode

Peripheral Interface (SPI) and software protocol allowing

operation on a simple three-wire bus. The bus

•Low Power CMOS

—150µA Standby Current

—3mA Active Current

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.

•2.7V To 5.5V Power Supply

•Block Lock Protection

The X25040 also features two additional inputs that

provide the end user with added flexibility. By asserting

—Protect 1/4, 1/2 or all of E²PROM Array

•Built-in Inadvertent Write Protection

—Power-Up/Power-Down protection circuitry

—Write Latch

the HOLD input, the X25040 will ignore transitions on its

inputs, thus allowing the host to service higher priority

interrupts. The WP input can be used as a hardwire input to

the X25040 disabling all write attempts, thus providing

—Write Protect Pin

a mechanism for limiting end user capability of altering the

memory.

•Self-Timed Write Cycle

—5ms Write Cycle Time (Typical)

•High Reliability

—Endurance: 100,000 cycles per byte

—Data Retention: 100 Years

The X25040 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.

—ESD protection: 2000V on all pins

•8-Lead PDlP Package

•8-Lead SOIC Package
