9.1.3 User-supplied TQFP44 Adaptor / Socket

To solder the TQFP44 device directly on the appli-

cation board, or to solder a socket for connecting

the emulator probe, the application board should

provide the footprint described in Figure 72. This

footprint allows both configurations:

s Direct TQFP44 soldering

s YAMAICHI IC149-044-*52-S5 socket soldering

to plug either the emulator probe or an adaptor

board with an TQFP44 clamshell socket.
