AN981/1100 1/5 AN981 application note st92163 emulator and eprom footprint compatibility guidelines by microcontroller division application team introduction the purpose of this application note is to describe the means of using st92163 devices (eprom or otp) or emulators. this is due to the fact that otp devices are supplied in tqfp64 packages, while eprom devices are in cqfp64 packages and the emulation socket is based on a pqfp footprint and designed for pqfp64 packages. this document will list five solutions for using st92163 mcus or emulators: n emulation mode, n eprom mode (cqfp64 package) compatible with emulation mode, n otp mode (tqfp64 package) C yamaichi socket, reference ic149, compatible with emulation mode, C yamaichi clam shell socket, reference ic51-0644-1240ks-14584, without emulation ca- pacity, C emplas open-top socket, reference otq-64-0.8-02, without emulation capacity, n soldered tqfp64 package. 1
2/5 st92163 emulator and eprom footprint compatibility guidelines 1 adapting tqfp64 packages to pqfp64 sockets 1.1 emulation mode in emulation mode, the ic149 emulation socket must be soldered (smd) on the pcb with a pqfp64 footprint. the emulation probe (db286) is then inserted onto the emulation socket via the mechanical db292 adaptor. figure 1. emulation mode diagram note : the db286 probe board, db292 socket adaptor and the yamaichi ic149 socket are all included in the st9216x emulator kit. 1.2 eprom mode (cqfp64 package) a 64-pin ceramic quad flat package (cqfp64) is used for the eprom device. the cqfp64 device can be directly mounted on the yamaichi ic149 socket used for emulation and en- closed using an adapter cover that is included in the emulation kit. figure 2. eprom mode diagram db286 probe board emulation probe db292 socket adapter pqfp socket yamaichi ic149 socket cqfp64 device pqfp socket yamaichi ic149 socket 2
3/5 st92163 emulator and eprom footprint compatibility guidelines 1.3 otp mode (tqfp64 package) 1.3.1 yamaichi ic149 socket this solution enables the same printed-circuit board (pcb) with a pqfp64 footprint to be used in either emulation or otp (one-time programmable) mode. a db200 socket adapter is screwed onto the yamaichi ic149 pqfp socket that is soldered to the pcb. the tqfp64 otp device is then mounted on a db379 tqfp64 device adapter which is then placed on the db200 socket adapter. figure 3. emulation mode diagram note : the db379 tqfp64 device adapter uses an emplas open-top socket. 1.3.2 yamaichi clam shell socket the yamaichi clam shell socket (ref. ic51-0644-1240ks-14584) can also be used, but em- ulation mode is no longer available. in this case, the clam shell socket replaces the ic149 socket and is soldered directly to the pcb with a pin-through footprint. 1.3.3 emplas open-top socket the emplas open-top socket (ref. otq-64-0.8-02) can also be used, but emulation mode is no longer available. in this case, the open-top socket replaces the ic149 socket and is soldered directly to the pcb with a pin-through footprint. 1.4 soldered otp mode at the end of the development stage or in production, the otp tqfp device can be soldered directly to the pcb, with a tqfp64 -compatible footprint. db200 socket adapter pqfp socket yamaichi ic149 socket tqfp64 otp device db379 tqfp64 device adapter emplas open-top socket
