Supporting Collateral:
The Microchip AT28C256 is a high-performance 256Kbit Parallel EEPROM available in both Industrial and Military temp ranges, offering access times to 150ns with power dissipation of 440mW. Deselected, CMOS standby current is less than 200μA. 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 64bytes simultaneously. Features an internal Error Correction Circuit for extended endurance and improved data retention, in Military version. Optional Software Data Protection mechanism guards against inadvertent writes; and an extra 64 bytes of EEPROM enables device identification or tracking.
The AT28C256 is also available DUAL MARKED where applicable with the appropriate Standard Military Drawing Number - 5962-88525xxxx. See the datasheet for exact MIL product availability.
