Which communication protocol is faster?
Advantages of using SPI The protocol is simple as there is no complicated slave addressing system like I2C. It is the fastest protocol compared to UART and I2C.
Which offers the highest data rate among SPI I2C UART protocols?
Maximum data rate supported is about 230 Kbps to 460kbps. I2C supports 100 kbps, 400 kbps, 3.4 Mbps. Some variants also supports 10 Kbps and 1 Mbps. No Common Clock signal is used.
How fast can SPI transfer data?
60 Mbps
The SPI bus can run at high speed, transferring data at up to 60 Mbps over short distances like between chips on a board.
How fast is UART communication?
Two UARTs directly communicate with each other. The two signals of each UART device are named: Transmitter (Tx) Receiver (Rx)…Interface.

What is the difference between SPI I2C and UART?
SPI, I2C, and UART are quite a bit slower than protocols like USB, Ethernet, Bluetooth, and Wi-Fi, but they’re a lot simpler and use less hardware and system resources. SPI, I2C, and UART are ideal for communication between microcontrollers and between microcontrollers and sensors where large amounts of high speed data don’t need to be transferred.
What are the different types of SPI protocols?
SPI 1 Building Protocols. 2 Serial Peripheral Interface (SPI) Serial Peripheral Interface (SPI) is a clocked serial link. 3 Controller Area Network (CAN) Controller Area Network (CAN) is a multi-drop bus protocol, so it can support many communicating nodes. 4 Higher Layer Protocols. 5 CANtastic! 6 Endnotes.
What are the different types of communication protocols used in microcontrollers?
When we’re talking communication protocols, a UART, SPI and I2C are the common hardware interfaces people use in microcontroller development. This article will compare the various interfaces: UART, SPI and I2C and their differences.
How many devices can a UART or SPI Device Support?
A corollary to the number of pins, UARTs and SPI devices support a different number of devices. UART, leveraging only Tx and Rx for outbound communication, is effectively limited to 1 to 1 communication.
