X76F400 General Description

The X76F400 is a password access security supervisor, containing one 3968-bit Secure Serial Flash 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 X76F400 features a serial interface and software protocol allowing operation on a popular 2-wire bus. 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.
