1. I2C PROTOCOL (TUTORIAL) …….by Azad Mishra

2. I2C = Inter IC = Inter Integrated Circuit Developed by Philips semiconductor (Now NXP) Two serial wire: 1.serial data(SDA) 2.serial clock(SCL ) Since dedicated SCL and SDA it support synchronous communication Bidirectional data transfer (not simultaneously ) Introduction

3. Multi master support Byte oriented transfer(byte) Wide range of Bus speed 1.Standard mode = 100 kbps 2.Fast mode = 400 kbps 3.High speed mode = 1 mbps 4.High speed mode = 3.4 mbps 5.Ultra fast mode = 5 mbps Contd ………
