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 memory cards. The X76F101 utilizes Xicor’s proprietary Direct Write TM cell, providing a minimum endurance of 100,000 cycles and a minimum data retention of 100 years.
