Advantages of Serial Peripheral Interface (SPI)
- High Speed Data Transfer: SPI can supports the high-speed communication, it is suitable for rapid data transferring applications. This data transfer is depends upon the some microcontrollers and used peripheral devices. The high speed data transfer can be used to the where the speed the communication will be needed such as the real time data acquisition or interfacing of the high-performance sensor.
- Simple Hardware Requirements: SPI required for the few hardware components. It consists of the four signal lines such as SCK, MOSI, MISO, SS and used for the data transmission by the no complex protocols. These requirements can be maintains the low hardware costs and implementation is easier compared to the other communication protocols.
- Full-Duplex Communication: SPI supports the full-duplex communication that means transferring and receiving the data enables the bidirectional communication. This bidirectional communication can be enabled to the sufficient transferring the data and making the suitable for the applications required for the high speed communication.
- Multi Slave Devices: SPIC can be supported the multiple slave devices using the single master device. Each slave device is assigned to the slave select (SS) line, for allowing to the master for needed to select and communicate with the single slave devices. This capability enabled to the SPI to the interface with the different multiple peripheral devices in the system without need any hardware requirements.
- Widespread Adoption: SPI is the protocol which is wide range adopted communication protocol within the embedded systems industries of the electronics, with the available for the most support of the microcontrollers and the peripheral devices. This adaption can be ensured the compatibility between the different hardware components. This adaption can makes the SPI is reliable choice for the communication in a variety of the applications.
- Low Overhead: SPI have low overhead compared to the other communication protocols. And it do not require the complex addressing or data packetization. This low overhead reduces simplified the software implementation. Making SPI suitable for the applications which are limited processing resources.
- Flexible Configurability: SPI can be offered the flexible in configuration parameters like clock polarity (CPOL) and clock phase (CPHA) for the accommodation of the different types of peripheral devices. This configuration allowed to the SPI to the interface with the large range of devices such as sensors, memory chips, displays and other integrated circuits without the required significant changes to the software or hardware.
What is Serial Peripheral Interface (SPI)?
A Serial Peripheral Interface (SPI) facilitates short-distance communication between peripheral integrated circuits and microcontrollers. In this article, we will understand the components of SPI, applications of Serial Peripheral Interface (SPI), and more.
