FEATURES  
DESCRIPTION  
•64-bit Password Security  
—Five 64-bit Passwords for Read, Program  
The X76F640 is a Password Access Security Supervisor,  
containing one 65536-bit Secure Serial Flash array and  
and Reset  
•8192 Byte+32 Byte Password Protected Arrays  
one 256-bit Secure Serial Flash array. Access to each  
memory array is controlled by two 64-bit passwords.  
—Seperate Read Passwords  
—Seperate Write Passwords  
These passwords protect read and write operations of  
the memory array. A separate RESET password is used  
—Reset Password  
•Programmable Passwords  
•Retry Counter Register  
to reset the passwords and clear the memory arrays in the  
event the read and write passwords are lost.  
The X76F640 features a serial interface and software  
protocol allowing operation on a popular two wire bus.  
—Allows 8 tries before clearing of both arrays  
—Password Protected Reset  
The bus signals are a clock Input (SCL) and a bidirectional  
data input and output (SDA). Access to the device  
•32-bit Response to Reset (RST Input)  
•32 byte Sector Program  
is controlled through a chip select (CS) input, allowing  
any number of devices to share the same bus.  
•400kHz Clock Rate  
•2 wire Serial Interface  
•Low Power CMOS  
The X76F640 also features a synchronous response to reset  
providing an automatic output of a hard-wired 32-bit  
—2.7 to 5.5V operation  
—Standby current Less than 1µA  
—Active current less than 3 mA  
data stream conforming to the industry standard for  
memory cards.  
•High Reliability Endurance:  
—100,000 Write Cycles  
The X76F640 utilizes Xicor’s proprietary Direct WriteTM cell,  
providing a minimum endurance of 100,000 cycles  
•Data Retention: 100 years  
•Available in:  
and a minimum data retention of 100 years.  
—8 lead SOIC  
—SmartCard Module
