The microcontroller used are usually constructed as an integrated semiconductor elements, are used in increasingly always newer technologies.

p0003Microcontrollers are increasingly used which have a small amount of memory, for example, 2 KB (kilo bytes), 4 KB or 8 KB. The different types of memory are used. While in recent years the OTP technology (One Time Programmable technology) is used for only one-time storing a program in the microcontroller will be strengthened in future applied flash memory technologies. Such flash microcontrollers can be programmed up to 100,000 times more with new programs.

p0004In the production of Domophons the Flash microcontroller to be programmed with the appropriate programs and then delivered to the customer. Reprogramming the Flash microcontroller by the customer is currently not possible because the customer would have to make itself more manipulations on the unit. For a new programming of flash microcontrollers, the device typically must be opened and an adapted programming adapters are attached to the microcontroller.

p0005From the state of the art as another solution applying Headers or sockets on the circuit board known. About the edge connectors or sockets that flash microcontrollers can be reprogrammed by means of a plug. Disadvantage of these programming options is an uncomfortable waste handling or generating additional costs related to components such as plugs or sockets.
