X24128

400kHz 2-Wire Serial EEPROM with Block Lock^™

DESCRIPTION

FEATURES

• Save critical data with programmable block lock

protection

—Block lock (0, 1/4, 1/2, or all of EEPROM array)

—Software write protection

The X24128 is a CMOS Serial EEPROM, internally

organized 16K x 8. The device features a serial inter-

face and software protocol allowing operation on a

simple two wire bus.

—Programmable hardware write protect

• In circuit programmable ROM mode

• 400kHz 2-wire serial interface

—Schmitt trigger input noise suppression

—Output slope control for ground bounce noise

elimination

• Longer battery life with lower power

—Active read current less than 1mA

—Active write current less than 3mA

—Standby current less than 1µA

• 2.5V to 5.5V power supply version

• 32 word page write mode

—Minimizes total write time per word

• Internally organized 16K x 8

• Bidirectional data transfer protocol

• Self-timed write cycle

—Typical write cycle time of 5ms

• High reliability

Three device select inputs (S –S ) allow up to eight

devices to share a common two wire bus.

A Write Protect Register at the highest address location,

FFFFh, provides three write protection features: Soft-

ware Write Protect, Block Lock Protect, and Program-

mable Hardware Write Protect. The software write

protect feature prevents any nonvolatile writes to the

device until the WEL bit in the write protect register is

set. The Block Lock protection feature gives the user

four array block protect options, set by programming two

bits in the write protect register. The programmable

hardware write protect feature allows the user to install

the device with WP tied to V , write to and Block Lock

the desired portions of the memory array in circuit, and

then enable the In Circuit Programmable ROM Mode by

programming the WPEN bit HIGH in the Write Protect

array, including the Write Protect Register itself, are per-

manently protected from being erased.

—Endurance: 100,000 cycles

—Data retention: 100 years

• 8-lead XBGA

Xicor EEPROMs are designed and tested for applica-

tions requiring extended endurance. Inherent data

retention is greater than 100 years.

• 14-lead SOIC
