MPC860DC

The MPC860DC PowerPC™ Quad Integrated Communications Controller (PowerQUICC) is a versatile 32-bit integrated microprocessor and peripheral combination that can be used in a variety of controller applications.It is a low-cost version of the MPC860 that provides an effective price/performance solution across a wide range of applications.The MPC860DC,like the MPC823ECZT66B2,combines a high-performance PowerPC core with a multifaceted system integration package. Unless otherwise specified,the PowerQUICC unit will be referred to as the MPC860DC in this manual.The purpose of this manual is to describe the operation of all the MPC860DC functionality with concentration on the I/O functions. Additional details on the MPC860DC can be found in the PowerPC architectural specifications.

The following list summarizes the main features of the MPC860DC:(1)PowerPC Single-Issue Integer Core Performs Branch Folding and Prediction with Conditional Prefetch, but Without Conditional Execution;(2)Precise Exception Model;(3)High Performance (52K Dhrystone 2.1 MIPS @40MHz,3.3V,1.3W Total Power);(4)High Performance (52K Dhrystone 2.1 MIPS @40MHz, 3.3V,1.3W Total Power);(5)MPC8XX PowerPC System Interface, Including a Periodic Interrupt Timer,a Bus Monitor,and Real-Time Clocks;(6)Fully Static Design (0-40MHz Operation).

The MPC860DC is a combination of the embedded PowerPC core and integrated peripherals brought together to meet the demands of various communications and networking products.The MPC860DC is comprised of six modules that all use the 32-bit internal bus:An embedded PowerPC core,A system interface unit,Two UARTs and A serial peripheral interface.
