In-system programming (ISP), also called In-Circuit Serial Programming (ICSP), eliminates the physical removal of chips (i.e. microcontrollers, serial EEPROMs, flash memories) from the target PCB.
Xeltek in-system programming tools provide a convenient method for configuring microcontrollers and various serial devices. Users could simply program microcontrollers, Flash memories, PLDs, and FPGAs via the ISP cable. Devices are programmed in the target system or target hardware, making field applications more convenient than ever. Typically, a jumper/DIP switch enables in-system programming and a set of serial programming connector (such as an IDC connector) connects the target board(s) to the ISP programmer(s).
