The 24LC32AT-I/SN is an EEPROM (electrically-erasable programmable read-only memory) from Microchip. It has a Serial I2C (Inter-Integrated Circuit) two-wire interface, a 32Kbit capacity (4K x 8bit), the ability to operate at 400kHz, and an 8-pin Small Outline packaging format. It is a reliable, low-power memory device that allows easy serial data transfer between microcontrollers and other digital control systems.
