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 Xicor’s proprietary Direct Write

cell, providing a minimum endurance of 100,000 cycles

and a minimum data retention of 100 years.
