It is often desired to use a PC to read data from or write data to a memory key. The KeyLink programmers support all of the Serial Memory keys and connect to a PC via a USB or RS-232 port. The programmers come with Windows® drivers and a sample application. The sample application can be used for troubleshooting when integrating a memory key into an embedded design, as it provides a known-good way to communicate with the memory device. For those who wish to develop their own Windows®R applications, we offer a development kit with all of the necessary tools, including the programmer.
