Access can be controlled by three 64-bit programmable passwords, one for read operations, one for write operations and one for device configuration. The X76F041 features a serial interface and software protocol allowing operation on a simple 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 input (CS), allowing any number of devices to share the same bus. The X76F041 also features a synchronous response to reset; providing an automatic output of a pre-configured 32-bit data stream conforming to the ISO standard for memory cards. The X76F041.
