Serial communication is the most widely used approach to transfer information between data processing peripherals. In this article, the different types of Serial Communication Protocols will be discussed. Similarly there are several examples of Serial Communication Protocols such as CAN, ETHERNET, I2C, SPI, RS232, USB, 1-Wire, and SATA etc. Examples of Parallel Communication Protocols are ISA, ATA, SCSI, PCI and IEEE-488. Similarly the protocols are divided into two types such as Serial Communication Protocol and Parallel Communication Protocols. There are different types of data transfer available in the digital electronics such as serial communication and parallel communication. More specifically, the data bits are transmitted one at a time in sequential manner over the data bus or communication channel in Serial Communication. one after the other then the communication protocol is known as Serial Communication Protocol. This exchange of data bits in microcontroller is done by some set of defined rules known as communication protocols. In embedded systems, the communication means the exchange of data between two microcontrollers in the form of bits. The communication is very well known terminology which involves the exchange of information between two or more mediums. Before starting with Serial Communication Protocols, Let’s break the terminology in three parts.
