Only two bus lines are required: a serial data line (SDA) and a serialclock line (SCL). Serial, 8-bit oriented, bidirectional data transfers can bemade at up to 100 kbit/s in Standard-mode, up to 400 kbit/s in Fast-mode, upto 1 Mbit/s in Fast-mode Plus (Fm+), or up to Mbit/s in High-speed Fast-mode is a unidirectional mode with data transfers of up to 5 SemiconductorsUM10204I2C-bus specification and user manual ; seventh releaseModifications: Updated Table 5 Updated the terms "master/slave" to "controller/target" throughout to align with MIPI I3 Cspecification and NXP's Inclusive Language Project Added Section manual ; sixth releaseModifications: Figure 41 updated (recalculated) Figure 42 updated (recalculated) manual ; fifth manual Rev.

Data Channel (DDC) and Advanced Telecom Computing Architecture (ATCA). This document assists device and system designers to understand how the I2C-bus works and implement a working application. Various operating modes are described. It contains a comprehensive introduction to the I2C-bus data transfer, handshaking and bus arbitration schemes.
