The I2C communication protocol was first created by Philips Semiconductor in 1982, and since 2006, developers and embedded engineers have been permitted to implement the protocol without paying any licensing fees. Let's start with a basic overview of each protocol. We'll break down the features and benefits of both the I2C and SPI protocols, explain the difference between I2C and SPI, and give our best recommendation for how you should choose between the I2C vs SPI communication protocols for your next embedded device engineering project. In this week's blog post, we're taking a deep dive into the I2C vs SPI debate. It’s important to understand their differences in order to choose the best protocol for your project. The most common communication protocols that can fulfill these criteria for integrated circuits are the I2C (inter-integrated circuit) protocol and the SPI (serial peripheral interface) protocol. If your embedded systems project involves programming a microcontroller to interface with peripheral devices on a PCB, you will need to choose a wired communication protocol that effectively facilitates internal communication for your device. Wired protocols can facilitate internal communication (between devices on the same bus), or external communication (between devices on different buses)

Acknowledgements of received data, failed data transfers, or other status changesĬommunication protocols can be wired (requiring a physical interface to transmit data) or wireless (requiring no physical interface to transmit data).

#I2c vs uart performance software#

A communication protocol establishes rules that govern the transmission of data and information between separate hardware and/or software systems. Commonly known examples include USB (Types A and B, and the recently released Type-C), Ethernet, and Bluetooth. There are many different types of communication protocols used in computer hardware today. Just like humans can communicate with others using different languages, communication protocols facilitate data transfer between hardware, software, or a combination of the two. Communication protocols define the rules of communication, syntax, semantics, and how the system will recover from errors. A communication protocol is a defined system that allows two or more entities in a communications system to talk to each other.

#I2c vs uart performance portable#

The MAX3108 is ideal for portable and handheld devices, is available in a 25-bump (2.1mm x 2.1mm) 0.4mm pitch WLP package, and is specified over the -40☌ to +85☌ extended temperature range.Communication Protocols in Embedded SystemsĬommunication protocols are central to how we understand and develop embedded systems and devices.

When configured as outputs, they can be programmed to be open-drain outputs and sink up to 20mA of current.

#I2c vs uart performance generator#

A phase-locked loop (PLL), predivider, and fractional baud-rate generator allow high-resolution baud-rate programming and minimize the dependency of baud rate on reference clock frequency.įour GPIOs can be used as inputs, outputs, or interrupt inputs. The MAX3108 operates from a low supply voltage of 1.71V to 3.6V.īaud rates up to 24Mbps make the MAX3108 suitable for today’s high data rate applications.

A low 500♚ (max) supply current and tiny 25-bump WLP (2.1mm x 2.1mm) package make the MAX3108 ideal for low-power portable devices. Auto-sleep and shutdown modes help reduce power consumption during periods of inactivity.

#I2c vs uart performance serial#

The MAX3108 small form factor universal asynchronous receiver-transmitter (UART) with 128 words each of receive and transmit FIFOs is controlled through a serial I☬ or SPI controller interface.
