It was introduced by Motorola in 1980s and is widely used in embedded systems.

SPI Protocol stands for Serial Peripheral Interface Protocol. It can support up to 3.4 Mbps which is considerably high data speed. It uses two bidirectional transmission lines for the data transfer. This serial communication is used for short distance communication between two Integrated Circuits on the same base (PCB). It allows connection of multiple slave devices with one or more than one master device. I2C stands for Inter Integrated Circuits protocol. The CAN protocol is utilized for electronics networking in automobiles, aeroplanes and medical systems. It was the CAN protocol that completely changed the communication between advanced sensors.
SERIAL COMMUNICATION PROTOCOL ISO
This Serial Communication protocol was further standardized as ISO 11898 in 1993. To overcome these issues, Robert Bosch introduced CAN protocol in 1980s.
These features warranted extra bulky wiring and complex designs which increased costs and risks. 3 – Serial Communication Protocols CAN Protocolġ970’s was the era when automobile manufacturers started introducing new features such as anti lock braking, air conditioners, gear control, centrally operated door locks etc. 2 – Devices Using Serial Communication Serial Communication Protocolsįollowing are the Serial Communication Protocols:įig.

Examples of these low cost serial buses are SPI, I☬, and 1-Wire.įew examples of systems consisting serial communication are Morse Code Telegraphy, RS-232, RS 422, RS-423, RS-485, Universal Serial Bus, FireWire, Serial Attached SCSI, Serial ATA, PCI Express, etc.įig. It is therefore, many integrated circuits utilize the serial buses when the importance of speed does not exist. The cost of integrated circuits are a lot because of the large number of pins. Improved technology to ensure the integrity of signal as well as increased transmission and receiving speed of data per channel has made the serial ports a close competitor to parallel ports. 1 – Serial Communication – Data Flow through Single PathĪt small distances, serial buses are becoming more common and popular because the disadvantages of parallel buses prevails their advantage of simplicity. As the cost of establishing a parallel communication is very high and its configuration is lengthy and complex, the Serial communication is preferred for all major communication/computer networks.įig. Hence, for a two-way digital communication, we will only need two wires between the transmitter and receiver. Serial communication takes place by using only a single wire or line. This is directly opposite to the function of parallel communication, where several bits are sent together on a bus consisting of many wired lanes in parallel. How does an arrow shoots from the bow? One at a time, isn’t it? Same is the case with Serial Communication. Serial communication can be defined as the method of sending one bit of data at one point of time in succession through a bus. This post will discuss Serial Communication, its protocols, comparison of RS Standards and advantages of Serial Communication over Parallel Communication.
It became popular owing to its low cost installation and less space requirements. This stands for “million bits per second.Serial Communication is the simplest communication of all between a sender and receiver. This stands for “thousand bits per second,” which is a rate of measure for electronic data transfer. Bit: Unit of information so.Bitrate: number of bits transmitted per second (b) Expression: Bit rate = baud rate x the number of bits per signal unit.Baud: unit of signaling speed so.Baud rate: number of symbols transmitted per second (s) Expression: Baud rate = bit rate / the number of bits per signal unit.We already discuss SERIAL COMMUNICATIONmy previous article that is one of the parts of plc communication At the heart of it all is the Distributed Interfaces that all need to work together efficiently and reliably.
