![]() ![]() : 651 : 40īut according to the progress of memory device technology, recent flash memory programmers do not need high voltages. Regarding old PROM programmers, as the many programmable devices have different voltage requirements, every pin driver must be able to apply different voltages in a range of 0–25 Volts. Pocket-sized & USB Port interfaced " ICE for MCU" & Selects the device and interface type, and starts the programming process to read/ write/ erase/ blank the data inside the device. Usually device programmers are connected to a personal computer through a parallel port, : 364 USB port, Ī software program on the computer then transfers the data to the programmer, : 364 : 430 Other devices require the data on parallel pins, followed by a programming pulse with a higher voltage for programming the data into the device. ![]() Some devices have a serial interface : 232, pdf3įor receiving the programming data (including JTAG interface). Īfterwards the data is transferred from the programmer into the device by applying signals through the connecting pins. This way is called on-board programming, in-circuit programming, or in-system programming. In the latter case, device programmer is directly connected to the printed circuit board by a connector, usually with a cable. : 642, pdf15 If the device is not a standard DIP packaging, a plug-in adapter board, which converts the footprint with another socket, is used. In the former case, the target device is inserted into a socket (usually ZIF) on top of the programmer. Another is configuring the device on a printed circuit board. One is configuring the target device itself with a socket on the programmer. ![]()
