EEPROM Memory IC 32Kb (4K x 8) I²C 400 kHz 900 ns 8-TSSOP
The 24AA32A-I/ST is a 32 Kbit (4 K × 8) Serial EEPROM developed by Microchip Technology. It uses the I²C (Inter-Integrated Circuit) interface, allowing simple communication with microcontrollers and other digital systems.
This device is designed for non-volatile data storage, meaning it retains stored data even when power is removed. It is commonly used in applications such as configuration storage, calibration data, device identification, and logging.
The “I” variant indicates industrial temperature range, while “ST” refers to the TSSOP package.
