Embedded Communication Interfaces OSI (Open Systems Interconnection) Model Layer Protocols Internet Protocol (IP) User Datagram Protocol (UDP) Transmission Control Protocol (TCP) Well-Known Port Numbers OSI (Open Systems Interconnection) Model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven distinct layers. It serves as a universal language for computer…

Embedded Communication Interfaces USB Interface USB Differential Signaling NRZI-Encoded Data USB interface serves as a high-performance gateway that allows a microcontroller to communicate with external peripherals or a host PC using a standardized, hot-swappable connection. To move data from the digital logic of the processor to the physical copper wires, the system utilizes a MAC…

Embedded Communication Interfaces Local Interconnect Network (LIN) LIN Physical Layer Local Interconnect Network (LIN) is a low-cost, low-speed serial communication bus mainly used in automotive systems to connect simple devices that do not require the performance or complexity of CAN. LIN is a broadcasting, serial, one-wire interface, typically implemented as a sub-bus of a CAN…

Embedded Communication Interfaces CAN Flexible Data-Rate (CAN-FD) CAN and CAN FD Speed CAN FD Frame Format CAN Flexible Data-Rate (CAN-FD) is an enhanced version of the classic Controller Area Network (CAN) protocol, designed to support higher data throughput and larger payloads while remaining compatible with existing CAN networks. CAN FD frames have variable data rate…
