Parallel EEPROM

To meet the needs of military-grade and industrial products, Microchip provides a broad selection of traditional Parallel EEPROM devices. Microchip’s policy of customer-driven obsolesce enables the creation of longstanding-designs for a broad spectrum of products, including telecommunications, avionics and military applications, without the risk of forced redesign from supply limitations. To meet the demands of both industrial (-40°C to 85°C) and military-grade (-55°C to 125°C) temperature applications, our Parallel EEPROM devices are offered in a broad selection of densities (64 Kbit to 1 Mbit) and package options.

Why Design with Microchip’s Parallel EEPROMs?

  • Battery-Voltage (2.7V), low voltage (3V) and 5V devices
  • Industrial-grade device ROHS compliant: PLCC, SOIC, PDIP and TSOP
  • Military-grade ceramic hermetic packaging dual marked with Standard Microcircuit Drawings (SMD) part numbers
  • MIL-STD-883 testing
  • Internal Error Correction Circuit
  • Optional software data protection mechanism
  • Extra bits for device identification
