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.

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.
