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/sla

I2C-bus compatible ICs not only assist designers, they also give a wide range of benefits to equipment manufacturers because: •The simple 2-wire serial I2C-bus minimizes interconnections so ICs have fewer pins and there are not so many PCB tracks; result — smaller and less expensive PCBs.
