This modularity allows the emulation of many different devices with the addition of a processor module and device adapter, which provides a very cost effective multiprocessor emulation system. The device adapters for MPLAB ICE 2000 are inter- changeable assemblies that allow the emulator system to interface to a target application system. Device adapters also have control logic that allows the target application to provide a clock source and power to the processor module. The device adapters support PICmicro MCUs in DIP, SDIP and PLCC packages. Transition sockets, used along with a device adapter, provide a method of accommodating all PICmicro MCU packages, including SOIC, SSOP, PQFP and TQFP packages. 2.0 MPLAB ICE 2000 SYSTEM A brief overview of the different components of the system is shown in the figure below. Each component is discussed in the following subsections. FIGURE 2-1: MPLAB® ICE 2000 EMULATOR SYSTEM 2.1 Host to Pod Cable This is a standard parallel interface cable. MPLAB ICE 2000 is tested with a 6-foot cable. A longer cable may work, but is not ensured. The cable connects to a par- allel port on the PC. If a PC has a printer connected to an LPT device, it is recommended that an additional interface card be installed, rather than using a splitter or an A/B switch. 2.2 Emulator Pod The Emulator Pod contains emulator memory and control logic. MPLAB ICE 2000 contains a main board and an additional board for expanded trace memory and complex control logic. There are no field service- able parts in the pod. For more information on the pod, see the MPLAB ICE 2000 on-line help file in MPLAB IDE (Help>Topics) or the “MPLAB® ICE 2000 In-Circuit Emulator User’s Guide” (DS51488). The MPLAB ICE 2000 processor module is inserted into the pod for operation. 2.3 Processor Module The processor module contains the emulator chip, logic and low-voltage circuitry. There are no field-serviceable parts mounted on the printed circuit board housed within the processor module enclosure.
