PROGRAMMER FOR SERIAL EEPROMs KIT - DIY

Serial eeproms are finding more and more use in electronic devices these days. These small 8 pin devices offer non-volatile data storage and require minimal I/O lines to connect to them. This makes them ideal in many microcontroller based applications.

The programmer connects to the PC parallel port and is controlled by driver software running on the PC.
