The Inter-Integrated Circuit (I2C) bus provides bidirectional data transfer through a two-wire design (a serial data line [SDA] and a serial clock line [SCL]), and interfaces to external I2C devices such as serial memory (RAMs and ROMs), networking devices, LCDs, tone generators, and so on. The I2C bus may also be used for system testing and diagnostic purposes in product development and manufacturing.
