FEATURES

DESCRIPTION

The X25640 is a CMOS 65,536-bit serial E²PROM,

internally organized as 8K x 8. The X25640 features a

Serial Peripheral Interface (SPI) and software protocol

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

signalsareaclockinput(SCK)plusseparatedatain(SI)

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

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

number of devices to share the same bus.

• 1MHz Clock Rate

• Low Power CMOS

—200µA Standby Current

—5mA Active Current

• 5 Volt Power Supply

• SPI Modes (0,0 & 1,1)

• 8K X 8 Bits

—32 Byte Page Mode

• Block Lock Protection

—Protect 1/4, 1/2 or all of E²PROM Array

• Built-in Inadvertent Write Protection

—Power-Up/Power-Down protection circuitry

—Write Enable Latch

The X25640 also features two additional inputs that

provide the end user with added flexibility. By asserting

the HOLD input, the X25640 will ignore transitions on its

inputs, thus allowing the host to service higher priority

interrupts.TheWPinputcanbeusedasahardwireinput

—Write Protect Pin

• Self-Timed Write Cycle

—5ms Write Cycle Time (Typical)

• High Reliability

The X25640 utilizes Xicor’s proprietary Direct Write™

cell, providing a minimum endurance of 100,000 cycles

and a minimum data retention of 100 years.

—Endurance: 100,000 cycles

—Data Retention: 100 Years

—ESD protection: 2000V on all pins

• 8-Lead PDlP Package

• 14-Lead SOIC Package
