MPLAB(R)-ICE Transition Socket Specifications INTRODUCTION This document describes the transition sockets used with MPLAB-ICE, Microchip's in-circuit emulator. FIGURE 1: MPLAB-ICE Emulator System Parallel Cable Emulator Pod Processor Module with Cable Power Supply Cable Logic Probe Connector Device Adapter Transition Socket WHAT ARE TRANSITION SOCKETS? Transition sockets are devices that allow MPLAB-ICE device adaptors to interface 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. 2000 Microchip Technology Inc. DS51194D-page 1 MPLAB(R)-ICE 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 shorter product development cycle, and Reduced expense in the design, layout, and prototype testing. A typical product design cycle has two important phases: the prototype design phase and the production design phase. Traditionally, these phases were different simply because the prototype used a microcontroller 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 ARE THE CURRENTLY AVAILABLE TRANSITION SOCKETS? Microchip Technology currently offers the following transition sockets for use with our emulator systems: * * * * PDIP - 28-Lead, 0.300-inch Male to 0.600-inch Female SOIC - 8-, 14-, 18-, 20- and 28-Lead SSOP - 20- and 28-Lead QFP - 44-, 64- and 80-Lead Please check the Microchip web site (www.microchip.com) for the most current version of this document. DS51194D-page 2 2000 Microchip Technology Inc. MPLAB(R)-ICE HOW CAN I OBTAIN MAXIMUM BENEFIT FROM THE USE OF TRANSITION SOCKETS? Attention to component placement should be considered to provide adequate clearance for the transition socket interface to the PCB footprint. This is especially true for any tall components such as connector headers, radial components or voltage regulators. Refer to the transition socket mechanical drawings for dimensions. COMMENTS AND SUGGESTIONS ON TRANSITION SOCKET APPLICATIONS Attention to component placement should be considered in mating the adapter sockets to the SOIC/SSOP headers. If visual alignment is difficult in your application, c-shaped end brackets have been included to aid in header-to-adapter socket alignment. Clip the brackets onto the SOIC/SSOP header. The placement of via's around the Surface Mount Technology (SMT) layout area should be examined. Via's immediately adjacent to the end of a SMT pad may inadvertently come into contact with the header leads. Via's should be placed along the centerline of the SMT pad to lessen the chance of pin to pin shorts while soldering. The SOIC Header is designed for SOIC body width of 0.300-inch, the adapter leads should be cut to fit the 0.150-inch and 0.208-inch SOIC body widths. 2000 Microchip Technology Inc.

FIGURE 5: MQFP/TQFP Transition Socket Cable to Processor Module MQFP/TQFP Device Adapter MQFP/TQFP Transition Socket Target / Application Board The MQFP/TQFP transition socket is required for use along with the MQFP/TQFP device adapters. The device adapter is equipped with four socket strips that interface with the transition socket. Note: To avoid solder bridging, do not place via's within 0.025inch of the MQFP/TQFP footprint. Also, any via's near the MQFP/TQFP should be directly on the centerline of the pad. Microchip offers the following MQFP/TQFP transition sockets: * XLT44PT: One 44-Lead MQFP/TQFP transition socket * XLT64PT1 One 64-Lead MQFP/TQFP transition socket, PIC16C92X * XLT64PT2: One 64-Lead MQFP/TQFP transition socket, PIC17CXXX * XLT80PT: One 80-Lead MQFP/TQFP transition socket DS51194D-page 26 2000 Microchip Technology Inc.

DS51194D-page 27 MPLAB(R)-ICE TQFP TRANSITION SOCKET SOLDERING TIPS * Before soldering, consider keeping the break away tabs in place during soldering. * Use controlled soldering iron tip temperatures between 300 and 325 C (570 to 615 F) * If it is possible, use a PACE mini wave soldering iron tip or an equivalent tip design. * Plan to solder one (1 of 4) side first, then the opposite side, then remaining two sides. * Soldering iron tip movement should be in direction of the leads (backward and forward), not across the leads; dragging the tip across the leads may cause lead damage. * Use generous amounts of soldering flux to aid in the solder flow action. * If the breakaway tabs are removed after soldering (using a dental pick or equivalent), any solder bridging between leads can be repaired by simply gently touching the soldering tip to the lead tip. Remember the 64- and 80-pin TQFP headers are very delicate and can be damaged! DS51194D-page 28 2000 Microchip Technology Inc.
