X24320

400KHz 2-Wire Serial E²PROM with Block Lock^™

DESCRIPTION

FEATURES

• Save Critical Data with Programmable Block

Lock Protection

The X24320 is a CMOS Serial E²PROM, internally

organized 4K x 8.The device features a serial interface

and software protocol allowing operation on a simple

two wire bus. The bus operates at 400 KHz all the way

down to 1.8V.

—Block lock (0, 1/4, 1/2, or all of E²PROM array)

—Software write protection

—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

• 1.8V to 3.6V, 2.5V to 5.5V and 4.5V to 5.5V Power

Supply Versions

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: Software

Write Protect, Block Lock Protect, and Programmable

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 Hard-

ware Write Protect feature allows the user to install the

• 32 Word Page Write Mode

—Minimizes total write time per word

• Internally Organized 4K x 8

• Bidirectional Data Transfer Protocol

• Self-Timed Write Cycle

—Typical write cycle time of 5ms

• High Reliability

—Endurance: 1 million cycles

—Data retention: 100 years

• 8-Lead SOIC

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 pro-

gramming the WPEN bit HIGH in the Write Protect Reg-

ister. After this, the Block Locked portions of the array,

including the Write Protect Register itself, are perma-

nently protected from being erased.

Xicor E²PROMs are designed and tested for applica-

tions requiring extended endurance. Inherent data

retention is greater than 100 years.
