? 2004 microchip technology inc. ds51194k-page 1 introduction transition sockets are devices that allow mplab ? ice 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 specif ically designed to provide compatibility between two diff ering types of ic package formats. transition sockets are typ ically 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. th e 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. shorter product development cycle. 2. reduced expense in the design, layout and prototype testing. a typical product design cycle has two important phases: the prototype desig n phase and the production design phase. traditionally, these phases were differ- ent simply because the protot ype used a microcontrol- ler with a different packa ge type. however, with the availability of the transiti on 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 modu le and device adapter specification (ds51140). for more on mplab ice 4000 device adapters, see the mplab ice 4000 processor module and devi ce adapter specification (ds51298). please check the microchip web site (www.microchip.com) for the mo st current version of all documents. 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 connec- tor headers, radial compone nts or voltage regulators. refer to the transition socket mechanical drawings for dimensions. transition socket specification mplab ? ice 2000/4000
mplab ? ice 2000/4000 ds51194k-page 2 ? 2004 microchip technology inc. transition socket applications ? comments and suggestions attention to component pl acement should be consid- ered in mating the adapter sockets to the soic/ssop headers. if visual alignment is difficult in your applica- tion, c-shaped end brackets have been included to aid in header-to-adapter sock et 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 pl aced along the centerline of the smt pad to lessen the chance of pin-to-pin shorts while soldering. the soic header is designe d 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. for information on packaging dimensions, please refer to ds00049. pdip transition socket a pdip transition socket and associated hardware is shown in figure 1. figure 1: pdip transition socket the pdip transition socket is a 0.300-inch male to 0.600-inch female adapter socket. microchip offers the following pdip transition socket: xlt28xp: one 28-lead pd ip adapter socket and two 28-lead gold stand-offs see the drawings in this se ction for layout dimensions. xlt28xp 28-lead dip 0.300-inch male to 0.600-inch female adapter socket cable to processor module pdip device adapter gold standoffs/adapters 0.300-inch male to 0.600-i nch female adapter socket target/application board (pdip transition socket) 0.300" 0.100" 0.600" 1.400" 0.700" top view side view rear view front/
