Serial EEPROMs



Microchip Technology offers a full range of Serial EEPROM devices


Microchip Serial EEPROMs Microchip, the world’s most reliable EEPROM supplier, offers a full range of Serial EEPROM devices in numerous packages. EEPROM itself is a robust memory technology and is well-developed. It offers non-volatile storage like Flash memory, but for smaller storage volumes. It can be written and erased many times more than Flash, and has a more granular memory architecture. EEPROM also operates over a wider supply voltage range.

Microchip has over 20 years of experience producing and refining EEPROM devices. They are built around an extremely robust memory cell design giving them industry leading endurance and robustness. Every bit of every EEPROM is 100% tested under worst-case conditions, and all devices are subject to advanced burn-in testing. This testing is performed to eliminate devices which would fail in the field allowing Microchip to provide devices with zero infant mortality. As Microchip’s EEPROMs are compatible with the de facto industry standards, they can be used as drop-in replacements for competitor devices in most cases. Microchip’s extremely long product life cycles avoid end of life issues and reliable supply ensures availability.
