INTRODUCTION
The Processor Modules for MPLAB ICE are
interchangeable personality modules that allow
MPLAB ICE to be reconfigured for emulation of differ-
ent PICmicro
microcontrollers (MCUs). This modular-
ity allows the emulation of many different devices by
the addition of just a Processor Module and Device
Adapter, which makes for a very cost effective multipro-
cessor emulation system.
The Device Adapters for MPLAB ICE are interchange-
able assemblies that allow the emulator system to
interface to a target application system. Device Adapt-
ers also have control logic that allows the target appli-
cation to provide a clock source and power to the
Processor Module. The Device Adapters support PIC-
micro 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.

TERMINOLOGY
A brief overview of the different components of the sys-
tem is shown in the figure below. Each component is
discussed in the following subsections.

MPLAB ICE EMULATOR
SYSTEM
2.1
Host to Pod Cable
This is a standard parallel interface cable. MPLAB ICE
is tested with a 6-foot cable. A longer cable may work,
but is not guaranteed. The cable connects to a parallel
port on the PC. If a PC has a printer connected to an
LPT device, it is recommended that an additional inter-
face card be installed, rather than using a splitter or an
A/B switch.
2.2
Emulator Pod
The Emulator Pod contains emulator memory and con-
trol logic. MPLAB ICE 2000 contains a main board and
an additional board for expanded trace memory and
complex control logic. There are no field serviceable
parts in the pod. For more information on the pod, see
the
MPLAB ICE User’s Guide
(DS51159).
The MPLAB ICE 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 ser-
viceable parts mounted on the printed circuit board
housed within the Processor Module enclosure.
