X24325

Advanced 2-Wire Serial E PROM with Block Lock^TMProtection

FEATURES

DESCRIPTION

• 2.7V to 5.5V Power Supply

The X24325 is a CMOS 32,768 bit serial E PROM,

internally organized 4096 x 8. The X24325 features a

serial interface and software protocol allowing opera-

tion on a simple two wire bus.

• Low Power CMOS

—Active Read Current Less Than 1mA

—Active Write Current Less Than 3mA

—Standby Current Less Than 1µA

• Internally Organized 4096 x 8

• New Programmable Block Lock Protection

—Software Write Protection

Three device select inputs (S , S , S ) allow up to

eight devices to share a common two wire bus.

A Write Protect Register at the highest address loca-

tion, FFFh, provides three new write protection

features: Software Write Protect, Block Write Protect,

and Hardware Write Protect. The Software Write

Protect feature prevents any nonvolatile writes to the

X24325 until the WEL bit in the write protect register is

set. The Block Write Protection feature allows the user

to individually write protect four blocks of the array by

programming two bits in the write protect register. The

Programmable Hardware Write Protect feature allows

—Programmable hardware Write Protect

• Block Lock (0, 1/4, 1/2, or all of the E PROM

array)

• 2 Wire Serial Interface

• Bidirectional Data Transfer Protocol

• 32 Byte Page Write Mode

—Minimizes Total Write Time Per Byte

• Self Timed Write Cycle

—Typical Write Cycle Time of 5ms

• High Reliability

the user to install the X24325 with WP tied to V

—Endurance: 100,000 Cycles

—Data Retention: 100 Years

• Available Packages

program the entire memory array in place, and then

enable the hardware write protection by programming

a WPEN bit in the write protect register. After this,

selected blocks of the array, including the write protect

—14-Lead TSSOP

Xicor E PROMs are designed and tested for applica-

tions requiring extended endurance. Inherent data

retention is greater than 100 years.
