X25F047

SPI SerialFlash with Block Lock^TMProtection

FEATURES

DESCRIPTION

• 1MHz Clock Rate

• SPI Modes (0,0 & 1,1)

• 512 x 8 Bits

—16 Byte Small Sector Program Mode

• Low Power CMOS

The X25F047 is a CMOS 4K-bit SerialFlash, internally

organized as 512 x 8. The X25F047 features a Serial

Peripheral Interface (SPI) and software protocol

allowing operation on a simple four-wire bus. The bus

signals are a clock input (SCK) plus separate data in (SI)

and data out (SO) lines. Access to the device is

controlled through a chip select (CS) input, allowing any

number of devices to share the same bus.

—<1µA Standby Current

—<3mA Active Current during Program

—<400µA Active Current during Read

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

Power Supply Versions

There are eight options for programmable, nonvolatile,

Block Lock Protection available to the end user. These

options are implemented via special instructions

programmed to the part. The X25F047 also features a

PP pin that can be used for hardwire protection of the

part, disabling all programming attempts, as well as a

ProgramEnableLatchthatmustbesetbeforeaprogram

operation can be initiated.

• Block Lock Protection

—Block Lock Protect 0, any 1/4, 1st 1/2, First or

Last Sector of SerialFlash Array

• Built-in Inadvertent Program Protection

—Power-Up/Power-Down Protection Circuitry

—Program Enable Latch

—Program Protect Pin

• Self-Timed Program Cycle

—5ms Program Cycle Time (Typical)

• High Reliability

The X25F047 utilizes Xicor’s proprietary Direct Write^TM

cell, providing a minimum endurance of 100,000 cycles

per sector and a minimum data retention of 100 years.

—Endurance: 100,000 Cycles/Byte

—Data Retention: 100Years

—ESD: 2000V on all pins

• 8-Lead SOIC Package

• 8-Lead MSOP Package

• 8-Lead TSSOP Package

• 8-Pin Mini-DIP Package
