UM10204 I2C-bus specification and user manual Rev. 4 — 13 February 2012 User manual Document information Info Keywords Abstract Content I2C, I2C-bus, Standard-mode, Fast-mode, Fast-mode Plus, Fm+, Ultra Fast-mode, UFm, High Speed, Hs, inter-IC, SDA, SCL, USDA, USCL Philips Semiconductors (now NXP Semiconductors) developed a simple bidirectional 2-wire bus for efficient inter-IC control. This bus is called the Inter-IC or I2C-bus. Only two bus lines are required: a serial data line (SDA) and a serial clock line (SCL). Serial, 8-bit oriented, bidirectional data transfers can be made at up to 100 kbit/s in the Standard-mode, up to 400 kbit/s in the Fast-mode, up to 1 Mbit/s in the Fast-mode Plus (Fm+), or up to 3.4 Mbit/s in the High-speed mode. The Ultra Fast-mode is a uni-directional mode with data transfers of up to 5 Mbit/s. http://www.DataSheet4U.net/ datasheet pdf - http://www.DataSheet4U.net/ NXP Semiconductors UM10204 I2C-bus specification and user manual Revision history Rev v.4 Date 20120213 Description Update user manual.
