Idea evaluation system have single standing boards: standart board (External Memory Board) used possible applications. consits only 10108x with sockets different pinouts packages, configuration switches interface connectors ROM- IN-CIRCUIT- emulator side Application Board other side. customized board (Application Board) which developed every user every kind application. connection between these boards rather simple, application signals (exempted configuration) routed from External Memory Board Application Board. demonstration Application Board provided together with software better understanding 10108x developemt system will descriped later.
Boards description following sections described components PCBs. 1.2.1 External Memory Board components PCB's requires only voltage (+12.+14 VDC). will connect External Memory Board (supply connector). external memory work ROM- IN-CIRCUIT-emulator connected socket. reset line connected single connection point near Reset button. Instead emulator also commercial EPROM like M27C1024 connected. external Memory work 10108F CLCC68 PLCC68 package needed. case application runs OTP-memory, 10108E 10108F only necessary. Application Board supplied through 34-pin connector between boards. RESET Resets always active done following possibilities: There main switch board which able disconnected from power supply, which resets components boards. This possibility used, chip external memory mode. chip reseted that case supply. Working external memory mode gives following additional possibilities: case software send Emulator, boards reseted automatically. Reset reset button emulator. Reset reset button 10108F.
