World-Class Serial EEPROMs


We have been manufacturing serial EEPROMs for over 30 years. With the industry’s largest portfolio, we provide a full range of densities and communication protocols to meet your needs. Our quality and reliability set us apart and are significant reasons why we ship over one billion serial EEPROMs each year.

Why Use Microchip's Serial EEPROMs?

Why Design with Our Serial EEPROMs?


  • Innovative Bus Types: Single-wire and UNI/O® bus for pin-constrained applications and accessory authentication
  • Industry-Standard Bus Types: I2C, SPI and Microwire
  • Complete Product Line: Full range of densities from 128 bits to 4 Mbit to scale with your design
  • Long product life cycles: Our practice of customer-driven obsolescence removes the risk of forced redesigns
  • Extended Temperature and Voltage Ranges: Operation from -40°C to 150°C and 1.5V to 5.5V for industrial and automotive applications
  • Reliability: Endurance of one million erase/write cycles and over 200 years of data retention
  • Quality: QS9000 compliant, ISO/TS16949 compliant, AEC-Q100 compliant, RoHS compliant, Pb-free

Pre-Programmed MAC Address and Unique ID EEPROMs

Need a MAC address but don’t want to buy in bulk? Or do you maybe need a generic unique ID? Microchip makes serialization easy with pre-programmed EEPROMs including IEEE EUI-48™ and EUI-64™ addresses and unique 32-bit and 128-bit Microchip-defined serial numbers.

Tiny 4-Ball WLCSP EEPROMs

Do you have a space-constrained application? Or are you looking to integrate EEPROM memory into your module? These tiny 4-ball Wafer Level Chip Scale Package (WLCSP) EEPROMs will fit on the tip of your pen. They are ideal for applications where tiny matters, including smartphones, high-frequency cable ends, cameras, handheld and medical devices. Advanced features like software write protection and configurable hardware addressing allow full I2C functionality while only requiring four physical connections.

Single-Wire and UNI/O Bus EEPROMs

Want to learn more about our innovative communication buses that use just one pin to interface with a microcontroller (MCU)? Discover how to reduce the number of pins needed for your design with our single-wire and UNI/O Bus EEPROMs.

DIMM-DDR2/DDR3/DDR4 EEPROMs

We offer JEDEC-compliant Serial Presence Detect (SPD) EEPROMs for use in DRAM Dual Inline Memory Modules (DIMM). These include software write protection features for the lower 128 bytes of the EEPROM that can be made permanent.

Development Tools


Serial EEPROM PIM PICtail Modules

Serial EEPROM PIM PICtail™ Pack

Part Number: AC243003

The serial EEPROM PIM PICtail modules are a series of boards designed around our serial EEPROM devices. These boards are designed to interface with the PICtail Plus connector as well as the MPLAB® Starter Kit for Serial Memory Products and the PICkit™ 4 probrammer/debugger allowing you to get started right out of the box.

Serial Memory SPI Evaluation Kit
