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]
Modern high speed serial interfaces such as PCIe [2] [3] [4] send data several bits at a time using modulation/encoding techniques such as PAM4 which groups 2 bits at a time into a single symbol, and several symbols are still sent one at the time. This replaces PAM2 or non return to zero (NRZ) which only sends one bit at a time, or in other ...
The 8250 UART (universal asynchronous receiver-transmitter) is an integrated circuit designed for implementing the interface for serial communications. The part was originally manufactured by the National Semiconductor Corporation. It was commonly used in PCs and related equipment such as printers or modems.
Most serial communications designs send the data bits within each byte least significant bit first. Also possible, but rarely used, is most significant bit first; this was used, for example, by the IBM 2741 printing terminal. The order of bits is not usually configurable within the serial port interface but is defined by the host system.
Inter-Integrated Circuit Sound (I²S, pronounced "eye-squared-ess" [citation needed]) is a serial interface protocol for transmitting two-channel, digital audio as pulse-code modulation (PCM) between integrated circuit (IC) components of an electronic device. An I²S bus separates clock and serial data signals, resulting in simpler receivers ...
Using a Bus Pirate, a developer can use a serial terminal to interface with a device, via such hardware protocols as SPI, I 2 C and 1-Wire. The Bus Pirate is capable of programming low-end microcontrollers, such as Atmel AVRs and Microchip PICs. Programming using more advanced protocols such as JTAG and SWD is possible, but is discouraged due ...
ICSPCLK - Clock line of the serial data interface. This line swings from GND to V dd and is always driven by the programmer. Data is transferred on the falling edge. ICSPDAT - Serial data line. The serial interface is bi-directional, so this line can be driven by either the programmer or the PIC depending on the current operation.
UniPro (or Unified Protocol) is a high-speed interface technology for interconnecting integrated circuits in mobile and mobile-influenced electronics. The various versions of the UniPro protocol are created within the MIPI Alliance (Mobile Industry Processor Interface Alliance), an organization that defines specifications targeting mobile and ...
