DESCRIPTION
The X76F128 is a Password Access Security Supervisor,
containing one 131072-bit Secure SerialFlash array and
one 512-bit Secure SerialFlash array. Access to each
memory array is controlled by two 64-bit passwords.
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 passwords are lost.
The X76F128 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). Access to the device
is controlled through a chip select (CS) input, allowing
any number of devices to share the same bus.
The X76F128 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 X76F128 utilizes Xicor’s proprietary Direct Write
cell, providing a minimum endurance of 100,000 cycles
and a minimum data retention of 100 years.
