DESCRIPTION
The X76F100 is a Password Access Security Supervi-
sor, containing one 896-bit Secure SerialFlash array.
Access to the memory array can be controlled by two
64-bit passwords. These passwords protect read and
write operations of the memory array.
The X76F100 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 X76F100 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 X76F100 utilizes Xicor’s proprietary Direct Write
cell, providing a minimum endurance of 100,000
cycles and a minimum data retention of 100 years.
