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.

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.
