Microcontroller programmers are usually dedicated to the devices of one particular manufacturer. This multi-programmer, however, can not only program the most important mid-range microcontrollers made by Atmel (and soon also Microchip), but also serial EEPROMs. Thanks to its USB interface, programming is simple, flexible and quick. This multi-programmer is tailored to the requirements of the semi-professional user. It is not designed for the entire range of microcontrollers from one particular manufacturer, but rather for general use with standard 8-bit microcontrollers which have limited memory capacity. The hardware is capable of programming microcontrollers from more than one manufacturer (currently Atmel and Microchip) as well as serial EEPROMs. Since these use different programming algorithms and voltages, this is something of an unusual feature.
