• Built-in inadvertent write protection

—Power-up/power-down protection circuitry

—Write enable latch

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

internally organized as 16K x 8. The X25128 features

a Serial Peripheral Interface (SPI) and software proto-

col, allowing operation on a simple three-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.

The X25128 also features two additional inputs that

provide the end user with added ﬂexibility. By asserting

the HOLD input, the X25128 will ignore transitions on

its inputs, thus allowing the host to service higher pri-

ority interrupts. The WP input can be used as a hard-

wire input to the X25128 disabling all write attempts to

the status register, thus providing a mechanism for lim-

iting end user capability of altering 0, 1/4, 1/2 or all of

the memory.

—Write protect pin

• Self-timed write cycle

—5ms write cycle time (typical)

• High reliability

—Endurance: 1 million cycles

—Data retention: 100 years

—ESD protection: 2000V on all pins

• Packages

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.
