Parallel EEPROMs

To meet the needs of military-grade and industrial products, we provide a broad selection of traditional parallel EEPROM devices. Our practice 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 Our 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
