X24128

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

FEATURES

DESCRIPTION

• Save Critical Data with Programmable

Block Lock Protection

—Block Lock (0, 1/4, 1/2, or all of E PROM Array)

The X24128 is a CMOS Serial E PROM, internally

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

face and software protocol allowing operation on a

simple two wire bus.

—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 loca-

tion, 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

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

• 32 Word Page Write Mode

—Minimizes Total Write Time Per Word

• Internally Organized 16K x 8

• Bidirectional Data Transfer Protocol

• Self-Timed Write Cycle

, 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 Register. After

this, the Block Locked portions of the array, including

the Write Protect Register itself, are permanently

protected from being erased.

—Typical Write Cycle Time of 5ms

• High Reliability

—Endurance: 100,000 Cycles

—Data Retention: 100Years

• 14-Lead SOIC

• 16-Lead SOIC

• 8-Lead PDIP
