512 x 8 Bit

X25040

SPI Serial EEPROM with Block Lock^™Protection

FEATURES

DESCRIPTION

• 2MHz clock rate

• SPI modes (0,0 & 1,1)

• 512 X 8 bits

—16-byte page mode

• Low power CMOS

—10µA standby current

—3mA active current

• 2.7V To 5.5V power supply

• Block lock protection

The X25040 is a CMOS 4096-bit serial EEPROM,

internally organized as 512 x 8. The X25040 features a

Serial Peripheral Interface (SPI) and software protocol,

allowing operation on a simple three-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.

The X25040 also features two additional inputs that

provide the end user with added ﬂexibility. By asserting

the HOLD input, the X25040 will ignore transitions on

its inputs, thus allowing the host to service higher pri-

ority interrupts. The WP input can be used as a hard-

wire input to the X25040, disabling all write attempts,

thus providing a mechanism for limiting end user capa-

bility of altering the memory.

—Protect 1/4, 1/2 or all of EEPROM array

• Built-in inadvertent write protection

—Power-up/power-down protection circuitry

—Write latch

—Write protect pin

• Self-timed write cycle

—5ms write cycle time (typical)

• High reliability

The X25040 utilizes Xicor’s proprietary Direct Write^™

cell, providing a minimum endurance of 1,000,000

cycles per byte and a minimum data retention of 100

years.

—Endurance: 1,000,000 cycles per byte

—Data retention: 100 years

—ESD protection: 2000V on all pins

• 8-lead SOIC package
