X25138

5MHz SPI Serial E PROM with Block Lock Protection

FEATURES

DESCRIPTION

• 5MHz Clock Rate

• Low Power CMOS

The X25138 is a CMOS 128K-bit serial E²PROM,

internally organized as 16K x 8. The X25138 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.

<1mA Standby Current

<5mA Active Current

• 2.5V To 5.5V Power Supply

• SPI Modes (0,0 & 1,1)

• 16K X 8 Bits

32 Byte Page Mode

• Block Lock™ Protection

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

• Programmable Hardware Write Protection

In-Circuit Programmable ROM Mode

• Built-in Inadvertent Write Protection

Power-Up/Down protection circuitry

Write Enable Latch

The X25138 also features two additional inputs that

provide the end user with added ﬂexibility. By

asserting the HOLD input, the X25138 will ignore tran-

sitions on its inputs, thus allowing the host to service

higher priority interrupts. The WP input can be used as

a hardwire input to the X25138 disabling all write

attempts to the status register, thus providing a mech-

anism for limiting end user capability of altering 0, 1/4,

1/2 or all of the memory.

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

• Packages

The X25138 utilizes Xicor’s proprietary Direct Write^TM

cell, providing a minimum endurance of 100,000

cycles and a minimum data retention of 100 years.
