DESCRIPTION

FEATURES

• 64-Bit Password Security

• Three Password Modes

—Secure Read Access

The X76F041 is a password access security supervisor

device, containing four 128 x 8 bit SecureFlash arrays.

Access can be controlled by three 64-bit programmable

passwords, one for read operations, one for write opera-

tions and one for device conﬁguration.

—Secure Write Access

—Secure Conﬁguration Access

• Programmable Conﬁguration

—Read, Write and Conﬁguration Access

Passwords

—Multiple Array Access/Functionality

—Retry Register/Counter

• 8 Byte Sector Write

The X76F041 features a serial interface and software

protocol allowing operation on a simple two wire bus.The

bus signals are a clock input (SCL) and a bidirectional

data input and output (SDA). Access to the device is con-

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

number of devices to share the same bus.

• (4) 1K Memory Arrays

• ISO Response to Reset

• Low Power CMOS

—50µA Standby Current

—3mA Active Current

• 1.8V to 3.6V or 5V “Univolt” Read and Program

Power Supply Versions

The X76F041 also features a synchronous response to

reset; providing an automatic output of a pre-conﬁgured

32-bit data stream conforming to the ISO standard for

memory cards.

The X76F041 utilizes Xicor’s proprietary Direct Write^TM

cell, providing a minimum endurance of 100,000 cycles

per sector and a minimum data retention of 100 years.

• High Reliability

—Endurance: 100,000 Cycles

—Data Retention: 100Years

—ESD Protection: 2000V on All Pins
