FEATURES

DESCRIPTION

The X25128 is a CMOS 131,072-bit serial E²PROM,

internally organized as 16K x 8. The X25128 features

•2MHz Clock Rate

•SPI Modes (0,0 & 1,1)

•16K X 8 Bits

—32 Byte Page Mode

a Serial Peripheral Interface (SPI) and software protocol

allowing operation on a simple three-wire bus.

•Low Power CMOS

—<1µA Standby Current

The bus signals are a clock input (SCK) plus separate data

in (SI) and data out (SO) lines. Access to the

—<5mA Active Current

•2.7V To 5.5V Power Supply

device is controlled through a chip select (CS) input,

allowing any number of devices to share the same

bus.

•Block Lock Protection

—Protect 1/4, 1/2 or all of E PROM Array

The X25128 also features two additional inputs that

provide the end user with added flexibility. By

•Built-in Inadvertent Write Protection

—Power-Up/Power-Down protection circuitry

—Write Enable Latch

asserting the HOLD input, the X25128 will ignore tran-

sitions on its inputs, thus allowing the host to service

—Write Protect Pin

higher priority interrupts. The WP input can be used as a

hardwire input to the X25128 disabling all write

•Self-Timed Write Cycle

—5ms Write Cycle Time (Typical)

•High Reliability

—Endurance: 100,000 cycles

—Data Retention: 100 Years

attempts to the status register, thus providing a mech-

anism for limiting end user capability of altering 0, 1/4,

1/2 or all of the memory.

—ESD protection: 2000V on all pins

•14-Lead SOIC Package

•16-Lead SOIC Package

•8-Lead PDIP Package

The X25128 utilizes Xicor’s proprietary Direct Write™ cell,

providing a minimum endurance of 100,000

cycles and a minimum data retention of 100 years.
