AT24C16B in 24LCxx / AT24Cxx I2C EEPROM Family
The AT24C16B is a 16-Kbit serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) manufactured by Microchip Technology. It is organized as 2,048 words of 8 bits each and utilizes a standard two-wire I2C interface. Designed for low-power and low-voltage applications, this memory family is widely used for non-volatile parameter storage where data integrity and physical space are critical constraints in embedded designs. It operates across a wide voltage range from 1.8V to 5.5V.
Variants in This Sub-Family
Variants within the AT24C16B sub-family are distinguished primarily by their package types, temperature ratings, and operating voltage ranges. Options include industrial-grade parts rated for -40C to +85C and automotive-grade versions with higher thermal tolerance. Packaging options range from traditional through-hole PDIP to ultra-thin UDFN and VFBGA for high-density mobile applications. Some specific variants may also offer different hardware write-protect pin configurations.
