1.0 INTRODUCTION
The processor modules for MPLAB
®
ICE 2000 are
interchangeable personality modules that allow
MPLAB ICE 2000 to be reconfigured for emulation of
different PIC
®
microcontrollers (MCUs). This modular-
ity 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 PIC
MCUs in DIP, SDIP and PLCC packages.
Transition sockets, used along with a device adapter,
provide a method of accommodating all PIC 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.

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.
