INTRODUCTION
Transition sockets are devices that allow MPLAB
2000 and MPLAB ICE 4000 device adapters to inter-
face to sockets on customer products that differ from
the standard emulator adapter connection.
Embedded microcontrollers/microprocessors come in
many different types of IC packages, (i.e., DIP, PLCC,
SOIC, SSOP, MQFP, etc.). Typically, development
cycle components are EPROM based and, as a result,
are provided in larger windowed package formats such
as DIP or PLCC. Production components are primarily
preprogrammed ROM, OTP or Flash-based and are
often in very compact SOIC, SSOP, MQFP or PQFP
package formats.
The MPLAB ICE solution is transition sockets. A
transition socket is specifically designed to provide
compatibility between two differing types of IC package
formats.
Transition sockets are typically composed of two parts:
the DIP adapter socket and the SOIC/SSOP header.
The DIP adapter socket is designed to plug into the
emulator system’s DIP device adapter on one side and
the header on the other. The header is then soldered
down to the target application.
The QFP Adapter is a single part soldered directly to
the target application and fits into the QFP device
adapter.
WHY SHOULD I USE TRANSITION
SOCKETS IN MY PRODUCT DESIGN?
There are two very significant advantages to using
transition sockets:
1.
2.
A typical product design cycle has two important
phases: the prototype design phase and the production
design phase. Traditionally, these phases were differ-
ent simply because the prototype used a microcontrol-
ler with a different package type. However, with the
availability of the transition sockets, the prototype
design can be identical to the production design
because a transition socket can be used to bridge the
microcontroller package differences.

WHAT TRANSITION SOCKETS ARE
CURRENTLY AVAILABLE?
Microchip Technology currently offers the transition
sockets listed in the Table of Contents following this
introductory section.
The Product Line Card (DS00148) lists the transition
sockets available for each device adapter of the
MPLAB ICE 2000 or 4000 System. For more on
MPLAB ICE 2000 device adapters, see the MPLAB
ICE 2000 Processor Module and Device Adapter
Specification (DS51140). For more on MPLAB ICE
4000 device adapters, see the MPLAB ICE 4000
Processor Module and Device Adapter Specification
(DS51298).

HOW CAN I OBTAIN MAXIMUM
BENEFIT FROM THE USE OF
TRANSITION SOCKETS?
Attention
considered to provide adequate clearance for the
transition socket interface to the PCB footprint. This is
especially true for any tall components such as connec-
tor headers, radial components or voltage regulators.
Refer to the transition socket mechanical drawings for
dimensions.
