DESCRIPTION
The X76F200 is a Password Access Security Supervisor,
containing one 1920-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 X76F200 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).
The X76F200 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 X76F200 utilizes Xicorâs proprietary Direct WriteTM
cell, providing a minimum endurance of 100,000 cycles
and a minimum data retention of 100 years.
