The MPC860ADS is an Applications Development System (ADS) designed to aid hardware and software developers of the MPC860 PowerQUICC, PowerPC QUad Integrated Communication Controller, in quickly evaluating and developing applications for MPC860ADS. All of the hardware resources needed to download and debug application software are provided, such as large blocks of flash and Dynamic RAM for the processor, serial port, clock generation option circuitry, logic analyzer connectors, expansion connectors as well as monitor/debugger hardware and software. The logic analyzer connectors provide the user with access to all of the processor's pins in order to monitor bus activity. The expansion connectors let the user attach user hardware applications and utilize board resources to verify a design.

To serve as a convenient platform for software development, the MPC860ADS is provided with MPC8Bug, a monitor/debugger, for the PowerQUICC. The monitor/debugger provides operations of memory dump and set, single instruction execution, breakpoints and downloads, as well as a self-test verification suite. MPC860ADS is downloaded via the MPC860ADI-PC or MPC860ADI-SUN4 which plugs into the user host system and connected to the ADS via a parallel ribbon cable.

The MPC860ADS board has a Ball Grid Array (BGA) socket to accomodate the MPC860 and its successors.
