X76F400 - Secure Serial Flash

Description

The X76F400 is a password access security supervisor, containing one 3968-bit Secure SerialFlash 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.

Features

  • 64-bit password security.
  • One array (496 bytes) two passwords (16 bytes).
  • Read password.
  • Write password.
  • Programmable passwords.
  • Retry counter register.
  • Allows 8 tries before clearing of the array.
  • 32-bit response to reset (RST input).
  • 8 byte sector write mode.
  • 1MHz clock rate.
  • 2-wire serial interface.
  • Low power CMOS.
  • 2.5 to 5.5V operation.
  • Standby current less than 1µA.
