It is created with an intention of communication between chips reside on the same Printed Circuit Board (PCB). It is commonly usually used to interface slow speed ICs to a microprocessor or a microcontroller. It is a master-slave protocol, usually a processor or microcontroller is the master and other chips like RTC, Temperature Sensor, EEPROM will be the...
