Size reduction, enhancement of capabilities, reduction of power consumption, and increasing the speeds of electronic devices, as well as their microcontrollers, have been the trend since the invention of the integrated circuit by Jack Kilby at Texas Instruments. Serial and parallel data transfer plays an important role in communication between ICs and modules. CAN and I2C are two protocols for networking between ICs and modules using serial data transfer. Provide your concept of CAN and I2C.
