更多文档...

High-performance 256K EEPROM offers access times to 70ns with power dissipation of 440mW. Deselected, CMOS standby current is less than 5mA .It is accessed like static RAM for the read or write cycle without external components. It contains a 64-byte page register to allow writing of up to 64 bytes simultaneously.The EEPROM features Internal error correction for extended endurance and improved data retention. Optional software data protection mechanism guards against inadvertent writes, and an extra 64 bytes of EEPROM enables device identification or tracking.
