BASICS OF INTER-INTEGRATED CIRCUITS(I2C)
Perior to I2C, chip-to-chip communications used many pins in a parallel interface.Many of these pins were used for inter-chip addressing, selection, control and data transfers. In a parallel interface,
8-data bits are typically transferred from a sender IC to a receiver IC in a single operation.
While
I2C performs chip-to-chip communications using only two wires in a serial interfaces allowing IC's to communicates with fewer pins. Two wires in the I2C bus carry addressing, selection, control, and data one bit at a time.
The Data(SDA) wires carries the data, while the clock(SCL) wire synchronizes the sender and receiver during the transfer.
