About Serial EEPROM Memory ICs

Serial EEPROM (Electrically Erasable Programmable Read-Only Memory) integrated circuits provide non-volatile data storage for electronic systems. Unlike parallel memory interfaces, serial EEPROMs use simple communication protocols (like Microwire, SPI, or I2C) that require fewer pins, making them ideal for space-constrained applications where board real estate is limited.

These memory devices are essential for storing configuration data, calibration settings, user preferences, and other critical information that must be preserved when power is removed. Their small form factor, low power consumption, and reliability make them suitable for everything from consumer electronics to industrial automation systems and automotive applications.

Packaging Options

Available in Tape & Reel (TR), Cut Tape (CT), and Digi-Reel® packaging options to suit your production requirements.
