The MC68360 QUad Integrated Communication Controller (QUICC?) is a versatile one chip integrated microprocessor and peripheral combination that can be used in a variety of controller applications. It particularly excels in communications activities. The QUICC (pro nounced “quick”) can be described as a next-generation MC68302 with higher performance in all areas of device operation, increased flexibility, major extensions in capability, and higher integration. The term quad comes from the fact that there are four serial communications controllers (SCCs) on the device; however, there are actually seven serial channels: four SCCs, two serial management controllers (SMCs), and one serial peripheral interface (SPI).
