A Queued Serial Peripheral Interface (QSPI; different to but has same abbreviation as Quad SPI described in § Quad SPI) is a type of SPI controller that uses a data queue to transfer data across an SPI bus. [19] It has a wrap-around mode allowing continuous transfers to and from the queue with only intermittent attention from the CPU.
It enables a secure serial digital communication between controller, sensor and actuator. The BiSS protocol is designed in B mode and C mode (continuously bidirectional mode). It is used in industrial applications which require transfer rates, safety, flexibility and a minimized implementation effort.
SPI-4.2 is a version of the System Packet Interface published by the Optical Internetworking Forum. It was designed to be used in systems that support OC-192 SONET interfaces and is sometimes used in 10 Gigabit Ethernet based systems.
The SPI 4.2 interface is composed of high speed clock, control, and data lines and lower speed FIFO buffer status lines. The high speed data line include a 16-bit data bus, a 1 bit control line and a double data rate (DDR) clock. The clock can run up to 500 MHz, supporting up to 1 GigaTransfer per second.
An example SPI with a master and three slave select lines. Note that all four chips share the SCLK, MISO, and MOSI lines but each slave has its own slave select. Chip select (CS) or slave select (SS) is the name of a control line in digital electronics used to select one (or a set) of integrated circuits (commonly called "chips") out of several connected to the same computer bus, usually ...
Low Pin Count interface Winbond chip Trusted Platform Module installed on a motherboard, and using the LPC bus. The Low Pin Count (LPC) bus is a computer bus used on IBM-compatible personal computers to connect low-bandwidth devices to the CPU, such as the BIOS ROM (BIOS ROM was moved to the Serial Peripheral Interface (SPI) bus in 2006 [1]), "legacy" I/O devices (integrated into Super I/O ...
Peripheral Sensor Interface (PSI5) is a digital interface for sensors. PSI5 is a two-wire interface, used to connect peripheral sensors to electronic control units in automotive electronics . Both point-to-point and bus configurations with asynchronous and synchronous data transmission are supported.
For data transfer via sliding contacts for mobile devices or optical or radio data transmission in open spaces, products from various manufacturers can be obtained, however they do not conform to any standard. PROFIBUS DP [6] uses two core screened cable with a violet sheath, [18] and runs at speeds between 9.6 kbit/s and 12 Mbit/s. [20]
