AT24C16A in 24LCxx / AT24Cxx I2C EEPROM Family
The AT24C16A is a high-performance 16-Kbit serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) based on the I2C (Two-Wire) protocol, originally developed by Atmel and now part of Microchip Technology. This sub-family provides 2,048 words of 8 bits each, optimized for low-power and low-voltage applications in industrial and commercial environments. It is frequently utilized for non-volatile storage of configuration data, calibration constants, and user preferences in resource-constrained embedded systems requiring reliable data retention.
Variants within the AT24C16A sub-family primarily differ by package type, ranging from standard 8-lead PDIP and SOIC to space-saving TSSOP, MAP, and SOT23-5 configurations. Performance distinctions are also found in operating voltage ratings, with specific suffixes denoting 1.8V or 2.7V minimum thresholds. Some versions are available with lead-free/halogen-free green packaging or different temperature grades including industrial and automotive specifications.
