PC860 PowerQUICC™ Processor
Fact Sheet
The MPC860 PowerQUICCTM is a versatile one-chip integrated microprocessor and peripheral combination that can be
used in a variety of controller applications, excelling particularly in communications and networking products. The
PowerQUICCcan be described as a next-generation MC68360 QUICC for network and data communication applications,
providing higher performance in all areas of device operation including flexibility, extensions in capability, and
integration. The MPC860 PowerQUICC, like the MC68360 QUICC integrates two processing blocks. One block is the
Embedded PowerPC Core and the second block is a Communication Processor Module (CPM) that closely resembles the
MC68360 CPM. The CPM supports four serial communications controllers (SCCs) on the device; however, there are
actually eight serial channels: four SCCs, two serial management controllers (SMCs), one serial peripheral interface (SPI)
and one I2C interface. This dual-processor architecture provides lower power consumption than traditional architectures
because the CP off-loads peripheral tasks from the Embedded PowerPC Core.
