I2c Overview Review

Each slave device has a unique 7-bit (or 10-bit) address, eliminating the need for complex Chip Select (CS) lines used in SPI.

The master pulls the SDA line low while SCL remains high. I2C Overview

The master releases the SDA line to high while SCL is high, signaling the end of transmission. Advantages and Limitations Understanding I2C Each slave device has a unique 7-bit (or

Data is sent in 8-bit bytes, most significant bit first, with each byte followed by an ACK/NACK bit. Advantages and Limitations Understanding I2C Data is sent

Uses a Serial Data Line ( SDA ) and a Serial Clock Line ( SCL ).

I2C communication is master-controlled. The master initiates, manages, and terminates communication, generating the clock signal.

I2C (Inter-Integrated Circuit), often pronounced "eye-squared-see" or "eye-two-see," is a popular, synchronous, multi-master/multi-slave communication protocol invented in 1982 by Philips Semiconductors (now NXP). It is used for short-distance, intra-board communication between a processor and low-speed peripherals such as sensors, LCDs, and memory chips. Its hallmark is using only two wires for communication, making it highly efficient for managing multiple devices on a single bus.
