Here are the components of Microchip’s MPLAB ICE 4000. In this ICE, the probe consists of the Processor Module, Device Adapter, and an optional Transition Socket. The physical package of the target microcontroller will determine whether a Transition Socket is needed or not. A common Emulator Pod is used for all Microchip devices, and the appropriate Processor Module is plugged into the Pod to support a specific processor or processor family. The Emulator Pod communicates to the PC via USB connection. Logic probe inputs and outputs on the Pod can monitor other signal lines with the trace buffer or allow external signals to initiate breakpoints. Triggers can be synchronized to other instruments, allowing a logic analyzer for instance, to use MPLAB ICE’s complex trigger settings to trace external signals.
