About EEPROM Memory ICs

Electrically Erasable Programmable Read-Only Memory (EEPROM) provides non-volatile data storage that retains information without power. Unlike flash memory, EEPROMs enable byte-level rewriting, making them ideal for frequent small-data updates in embedded systems where parameter adjustments or calibration data must persist through power cycles.

Serial EEPROMs like the DS2431P+T&R significantly reduce system complexity compared to parallel alternatives. Their compact footprints and minimal pin counts allow integration in space-constrained designs while consuming minimal power – critical advantages for portable electronics, smart sensors, and battery-backed systems where board real estate and energy efficiency are paramount.

Packaging Options

Available in Tape & Reel (TR), Cut Tape (CT), and Digi-Reel® formats for automated assembly compatibility. Specify your preferred packaging during checkout.
