About this product
24C32 is a 32 Kbit (4096 x 8) serial EEPROM for 5 V systems, accessed over the two-wire I2C interface. It stores calibration data, user settings and small amounts of logged information in microcontroller projects, and its address pins allow several devices to share one bus.

Frequently asked questions
How do I set the I2C address of the 24C32?
Tie the A0, A1 and A2 pins to VCC or GND to select the device address. This lets you put up to eight 24C32 devices on the same bus without address conflicts.
How do I wire it to a microcontroller?
Connect SDA and SCL to the microcontroller's I2C pins with pull-up resistors on both lines, and connect VCC and GND. Keep the bus voltage consistent with the microcontroller's logic level.
