SPI Serial E²PROM With Block Lock^TMProtection

FEATURES

DESCRIPTION

• 2MHz Clock Rate

• SPI Modes (0,0 & 1,1)

• 4K X 8 Bits

—32 Byte Page Mode

The X25320 is a CMOS 32768-bit serial E²PROM,

internally organized as 4K x 8. The X25320 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.

• Low Power CMOS

—<1µA Standby Current

—<5mA Active Current During Write

• 2.7V To 5.5V Power Supply

• Block Lock Protection

The X25320 also features two additional inputs that

provide the end user with added flexibility. By asserting

the HOLD input, the X25320 will ignore transitions on its

inputs, thus allowing the host to service higher priority

interrupts.TheWPinputcanbeusedasahardwireinput

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

• Built-in Inadvertent Write Protection

—Power-Up/Power-Down protection circuitry

—Write Enable Latch

—Write Protect Pin

• Self-Timed Write Cycle

—5ms Write Cycle Time (Typical)

• High Reliability

—Endurance: 100,000 cycles

—Data Retention: 100 Years

—ESD protection: 2000V on all pins

• 8-Lead PDlP Package

The X25320 utilizes Xicor’s proprietary Direct Write™

cell, providing a minimum endurance of 100,000 cycles

and a minimum data retention of 100 years.

• 8-Lead SOIC Package

• 14-Lead TSSOP Package
