Serial EEPROM
World-Class Serial EEPROM Devices
Specialty EEPROMs
Pre-Programmed MAC Address and Unique ID EEPROMs
Do you need a MAC address but don’t want to buy in bulk? Or do you need a generic unique ID? We make serialization easy with pre-programmed EEPROMs that include IEEE EUI-48™ and EUI-64™ addresses and unique 32-bit and 128-bit Microchip-defined serial numbers.
Tiny 4-Ball WLCSP EEPROMs
Our tiny 4-ball Wafer Level Chip Scale Package (WLCSP) EEPROMs will fit on the tip of your pen. They are excellent options for space-constrained applications like smartphones, high-frequency cable ends, cameras, handheld and medical devices.
Single-Wire and UNI/O Bus EEPROMs
Discover how our single-wire and UNI/O bus EEPROMs reduce the number of pins needed for your design. These innovative communication buses use just one pin to interface with a microcontroller (MCU).
DIMM-DDR2/3/4 EEPROMs
We offer JEDEC-compliant Serial Presence Detect (SPD) EEPROMs for use in DRAM Dual Inline Memory Modules (DIMM). These devices include software write protection features for the lower 128 bytes of the EEPROM that can be made permanent.
Featured
