The I2C Manual provides a broad overview of the various serial buses, why the I2C bus should be considered, technical detail of the I2C bus and how it works, previous limitations / solutions, ...

This application note describes an example of application in which the I2C module of the SH7145F is used to read/write data from/to a two-wire serial (I2C bus) EEPROM. Data communication is generally ...

This FAQ analyzes the open-drain physical layer and the nuances of register-level addressing to better understand I2C communication.

The circuit shown can be used to interface multiple serial devices to the I2C bus, even if they lack the extended-addressing capability required. Information transfer be-tween I2C devices connected to ...

The 12-bit MCP3221 analog-to-digital converter (ADC) incorporates an I2C interface in an SOT-23 package. The 400-kHz clock rate of the two-wire serial, I2C interface enables sampling rates up to 22.3 ...
