FEATURES  
DESCRIPTION  
• 64-bit Password Security  
—Five 64-bit Passwords for Read, Program  
and Reset  
• 8192 Byte+32 Byte Password Protected Arrays  
—Seperate Read Passwords  
—Seperate Write Passwords  
—Reset Password  
• Programmable Passwords  
• Retry Counter Register  
—Allows 8 tries before clearing of both arrays  
Password Protected Reset  
• 32-bit Response to Reset (RST Input)  
• 32 byte Sector Program  
• 400kHz Clock Rate  
The X76F641 is a Password Access Security Supervisor,  
containing one 65536-bit Secure SerialFlash array and  
one 256-bit Secure SerialFlash array. Access to each  
memory array is controlled by five 64-bit passwords  
each. These passwords protect read and write opera-  
tions of the memory array. A separate RESET password  
is used to reset the passwords and clear the memory  
arrays in the event the read and write passwords are lost.  
The X76F641 features a serial interface and software  
protocol allowing operation on a popular two wire bus.  
The bus signals are a clock Input (SCL) and a bidirec-  
tional data input and output (SDA).  
The X76F641 also features a synchronous response to  
reset providing an automatic output of a hard-wired 32-bit  
data stream conforming to the industry standard for  
memory cards.  
• 2 wire Serial Interface  
• Low Power CMOS  
—2.0 to 5.5V operation  
—Standby current Less than 1µA  
—Active current less than 3 mA  
• High Reliability Endurance:  
—100,000 Write Cycles  
TM  
The X76F641 utilizes Xicor’s proprietary Direct Write  
cell, providing a minimum endurance of 100,000 cycles  
and a minimum data retention of 100 years.  
• Data Retention: 100 years  
• Available in:  
—8 lead EIAJ SOIC  
—SmartCard Module
