Frequently asked questions
How do I wire the 24C16 to a microcontroller?
Connect SDA and SCL to the microcontroller's I2C pins, with pull-up resistors on both lines, plus VCC and GND. Make sure the bus voltage matches your microcontroller's logic level.
Is it compatible with 3.3V boards?
The device is specified for 5 V operation. When connecting to a 3.3 V board, check the logic-level and pull-up voltage requirements in the datasheet and use a level shifter if needed.
