The X76F101 is a Password Access Security Supervisor,
containing one 896-bit Secure Serial Flash 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 X76F101 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 bidirectional
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 X76F101 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
The X76F101 utilizes Xicor’s proprietary Direct WrTitMe
cell, providing a minimum endurance of 100,000 cycles and
a minimum data retention of 100 years.
