Integrated Communications Processors
MPC860
PowerQUICC
™
Family
Freescale Semiconductor’s PowerQUICC™
MPC860 family is designed to deliver a
versatile, on-chip integrated processor and
peripheral combination that can be used in a
variety of controller applications—excelling
particularly in communications and networking
products. Providing functionality beyond the
MPC850 family, the MPC860 family and
MPC855T derivative are engineered to provide
higher performance in all areas of device
operation including flexibility, extensions in
capability and integration. The 860 architecture
integrates two processing blocks: the
embedded 8xx core compatible with the Power
Architecture™ technology instruction-set
architecture (ISA), and the communications
processor module (CPM). The CPM is designed
to support four serial communications
controllers (SCCs), providing a total of eight
serial channels: four SCCs, two serial
management controllers (SMCs), one serial
peripheral interface (SPI) and one I
2
C interface.
This dual-processor architecture is designed to
provide lower power consumption than
traditional architectures because the CPM
offloads peripheral tasks from the embedded
8xx core.
