X76F641  
Secure SerialFlash  
FEATURES  
DESCRIPTION  
• 64-bit password security  
—Five 64-bit passwords for read, program and  
reset  
• 8192 byte+32 byte password protected arrays  
—Separate read passwords  
—Separate write passwords  
—Reset password  
The X76F641 is a Password Access Security Supervi-  
sor, 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 pass-  
words each. These passwords protect read and write  
operations 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 pass-  
words are lost.  
• 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 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).  
• 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  
• Data retention: 100 years  
• Available in:  
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.  
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.
