DESCRIPTION
Access to the memory array can be controlled by two 64-bit passwords. The bus signals are a clock input (SCL) and a bi-directional data input and output (SDA). The X76F400 also features a synchronous response to reset, providing an automatic output of a hard-wired 32-bit data stream, thereby meeting the industry standard for memory cards. The X76F400 utilizes Xicor’s proprietary Direct Write™ cell, providing a minimum endurance of 100,000 cycles and a minimum data retention of 100 years.
