Privacy PolicyWorld-Class Serial EEPROMs
Why Use 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.
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
Part Number: EV20F92A
This evaluation kit is an easy-to-use interactive user tool that demonstrates the best-in-class features, functionality and low-power operation of our SPI serial EEPROM devices. The included Graphical User Interface (GUI) makes it easy for you to configure and evaluate SPI serial EEPROMs, shortening the overall development time needed to bring new designs from prototype to production.
Serial Memory I2C Evaluation Kit
Part Number: DM160237
This evaluation kit is an easy-to-use interactive user tool that demonstrates the best-in-class features, functionality and low-power operation of our I2C serial EEPROM devices. The included Graphical User Interface (GUI) makes it easy for you to configure and evaluate I2C serial EEPROMs, shortening the overall development time needed to bring new designs from prototype to production.
