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 WriteTM  
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
