2-Wire SerialFlash with Block Lock^TMProtection

FEATURES

DESCRIPTION

The X24F128 is a CMOS SerialFlash Memory, inter-

nally organized 16K x 8. The device features a serial

interface and software protocol allowing operation on a

simple two wire bus.

• Save Critical Data With Programmable

Block Lock Protection

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

—Software Program Protection

—Programmable Hardware Program Protect

• In Circuit Programmable ROM Mode

• Longer Battery Life With Lower Power

—Active Read Current Less Than 1mA

—Active Program Current Less Than 3mA

—Standby Current Less Than 1µA

• 1.8V to 3.6V or 5V “Univolt” Read and

Program Power Supply Versions

• 32 Word Sector Program Mode

—Minimizes Total Program Time Per Word

• 100KHz 2-Wire Serial Interface

• Internally Organized 16K x 8

• Bidirectional Data Transfer Protocol

• Self-Timed Program Cycle

—Typical Program 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 Program Protect Register at the address location

FFFFh provides three program protection features:

Software Program Protect, Block Lock Protect, and

Hardware Program Protect. The Software Program

Protect feature prevents any nonvolatile writes to the

device until the PEL bit in the Program Protect

allows the user to individually block protect four blocks

of the array by programming two bits in the Program

Protect Register. The Programmable Hardware

Program Protect feature allows the user to install the

device with PP tied to V , program the entire memory

array in circuit, and then enable the hardware program

protection by programming a PPEN bit in the Program

Protect Register. After this, selected blocks of the

array, including the Program Protect Register itself, are

permanently protected from being erased.

—Endurance: 100,000 Cycles

—Data Retention: 100Years

• 16-Lead SOIC
