AT28HC256-90DM/883 概要
The Microchip AT28HC256is a high-performance 256Kbit Parallel EEPROM available in both Industrial andMilitary temp ranges, offering access times to 70ns with power dissipation of440mW. Deselected, CMOS standby current is less than 5mA. Accessed like staticRAM for the read or write cycle without external components, it contains a64-byte page register to allow writing of up to 64 bytes simultaneously. Featuresan internal Error Correction Circuit forextended endurance and improved data retention, in Military version. Optional Software Data Protection mechanism guardsagainst inadvertent writes; and an extra 64 bytes of EEPROM enables deviceidentification or tracking.
The AT28HC256 is also available DUAL MARKED where applicable with the appropriate Standard Military Drawing Number - 5962-886340xxx. See the datasheet for exact MIL product availability.
