AVR In-Circuit Programmer

 


The programmer is very simple to build. It contains one IC and a couple of connectors. As you can see below, with some ingenuity it is possible to squeeze all the circuitry into a DB25 connector shell. The IC can be a 74HC244 or a 74LS244.

The more normal means of construction is with a small circuit board, with the DB25 connector mounted on one edge, and a header to connect the ribbon cable. The programmer is designed to work with all the AVRâ„¢ family micros, and with the Atmel “ISP” programming software.
