Key Facts About I2C
- 1I2C uses only 2 bidirectional data lines (SDA and SCL) to enable communication between multiple devices on a shared bus.
- 2I2C supports data transfer rates up to 400 kbit/s in standard mode and up to 5 Mbit/s in high-speed mode.
- 3I2C devices are identified by a unique 7-bit address, allowing up to 128 devices to be connected on a single I2C bus.
- 4I2C is a synchronous protocol, with the clock signal (SCL) generated by the master device to synchronize data transfers.
- 5Key applications of I2C include interfacing sensors, EEPROM, real-time clocks, and LCD/OLED displays with microcontrollers.
