HostLink Protocol, Omron's protocol for communication over serial links. Interbus, Phoenix Contact's protocol for communication over serial links, now part of PROFINET IO; MECHATROLINK – open protocol originally developed by Yaskawa, supported by the MMA; MelsecNet, and MelsecNet II, /B, and /H, supported by Mitsubishi Electric. Modbus PEMEX ...
The USART's synchronous capabilities were primarily intended to support synchronous protocols like IBM's synchronous transmit-receive (STR), binary synchronous communications (BSC), synchronous data link control (SDLC), and the ISO-standard high-level data link control (HDLC) synchronous link-layer protocols, which were used with synchronous voice-frequency modems.
Full duplex communication in the default version of this protocol; Push-pull drivers (as opposed to open drain) provide relatively good signal integrity and high speed; Higher throughput than I²C or SMBus. SPI's protocol has no maximum clock speed, however: Individual devices specify acceptable clock frequencies; Wiring and electronics limit ...
The System Management Bus (SMBus or SMB) is a single-ended simple two-wire bus for the purpose of lightweight communication. Most commonly it is found in chipsets of computer motherboards for communication with the power source for ON/OFF instructions. The exact functionality and hardware interfaces vary with vendors.
The master initiates activity on the bus, simplifying the avoidance of collisions on the bus. Protocols are built into the master's software to detect collisions. After a collision, the master retries the required communication. A 1-Wire network is a single open drain wire with a single pull-up resistor. The pull-up resistor pulls the wire up ...
FPD-Link III's embedded control channel uses the I2C bus protocol between the source and destination in the first implementations (however, it is not limited to I2C). The I2C master can read and write to all the slaves on the other side of the FPD-Link III chipset, which is effectively transparent to the I2C master and slaves communications.
MII has two signal interfaces: A Data interface to the Ethernet MAC, for sending and receiving Ethernet frame data. A PHY management interface, MDIO, used to read and write the control and status registers of the PHY in order to configure each PHY before operation, and to monitor link status during operation.
