The I2C (Inter-Integrated Circuit) Bus invented in 1980 by Philips Semiconductors (NXP Semiconductors today) was a massive step forward in simplifying communications in embedded systems. It is a ...

Delivers the flexible, multiple-peripherals simplicity of I2C and the faster, lower-latency communication of SPI in a single, efficient, easier-to-use IP core Woodcliff Lake, New Jersey — September 5, ...

Several of the Mid-Range Enhanced Core PIC16 microcontroller devices have a Master Synchronous Serial Port (MSSP). The MSSP module can be used to implement either I2CTM or SPI communications protocol.

It’s probably fair to say that anyone reading these words understands conceptually how physically connected devices communicate with each other. In the most basic configuration, one wire establishes a ...

Debuting as the industry’s first family of I2C-controlled switches that can connect multiple devices with the same address on a single bus, the PCA954x switches allow voltage level shifting between ...

The maximum distance of an I2C bus depends on the capacitive loading. In typical applications, the length is limited to a few meters in standard mode. This is because a system has to be built to ...

Communicating with microcontrollers and other embedded systems requires a communications standard. SPI is a great one, and is commonly used, but it’s not the only one available. There’s also I2C which ...
