Overview
1
The MPC860 power quad integrated communications controller (PowerQUICC™) is a versatile one-chip
integrated microprocessor and peripheral combination designed for a variety of controller applications. It
particularly excels in communications and networking systems. The PowerQUICC unit is referred to as
the MPC860 in this hardware specification.
The MPC860 implements Power Architecture™ technology and contains a superset of Freescale’s
MC68360 quad integrated communications controller (QUICC), referred to here as the QUICC, RISC
communications proccessor module (CPM). The CPU on the MPC860 is a 32-bit core built on Power
Architecture technology that incorporates memory management units (MMUs) and instruction and data
caches.. The CPM from the MC68360 QUICC has been enhanced by the addition of the inter-integrated
controller (I
type of memory, including high-performance memories and new types of DRAMs. A PCMCIA socket
controller supports up to two sockets. A real-time clock has also been integrated.
