X25330

5MHz SPI Serial E PROM with Block Lock Protection

FEATURES

DESCRIPTION

• 5MHz Clock Rate

• Low Power CMOS

The X25330 is a CMOS 32K-bit serial E²PROM, inter-

nally organized as 4K x 8. The X25330 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.

<1µA Standby Current

<5mA Active Current

• 2.5V To 5.5V Power Supply

• SPI Modes (0,0 & 1,1)

• 4K X 8 Bits

32 Byte Page Mode

• Block Lock™ Protection

The X25330 also features two additional inputs that

provide the end user with added ﬂexibility. By

asserting the HOLD input, the X25330 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 X25330 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.

• Programmable Hardware Write Protection

In-Circuit Programmable ROM Mode

• Built-in Inadvertent Write Protection

• Self-Timed Write Cycle

5ms Write Cycle Time (Typical)

• High Reliability

The X25330 utilizes Xicor’s proprietary Direct Write^TM

cell, providing a minimum endurance of 100,000

cycles and a minimum data retention of 100 years.

Endurance: 100,000 cycles
