Микропроцессоры MPC860PCZQ66D4

MPU , 32BIT, 66MHZ, BGA-357

The MPC860 PowerQUICC™ versatile one-chip Integrated Microprocessor and Peripheral Combination designed for a variety of controller applications. 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 processor 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 (I²C) channel. The memory controller has been enhanced, enabling the MPC860 to support any 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.
