Inter-integrated circuit -interface

Serial Peripheral Interface Bus (SPI) and Inter-Integrated Circuit Bus (IIC or fc or I2C) These are industry-standard input/output interfaces and are becoming more common in the FPA world as control interfaces to ROICs. Many embedded microprocessors implement these two interfaces in their architecture this makes them attractive for use in an ROIC. This can simplify the camera control electronics design since most cameras have embedded microprocessors in them already.
