X76F128

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 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 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^TM cell, providing a minimum endurance of 100,000 cycles and a minimum data retention of 100 years.
