APPLICATION NOTE Atmel AVR600: STK600 Expansion, Routing and Socket Boards Atmel Microcontrollers Introduction This application note describes the process of developing new routing, socket and expansion cards for the Atmel STK 600. It also describes the physical parameters for creating such cards. The STK600 starter kit from Atmel has a sandwich design to match a specific part package and pin out to the generic pin headers. It also features an expansion area where most part pins are available. While the variety of IC packages is relatively limited, the number of possible pinouts increases rapidly with the number of pins. I.e. a 6-pin IC can have 720 (6 ) different pinouts The routing / socket card design provides a lowcost solution to support upcoming devices as the socket is the cost driving factor. STK600 users might also want to create their own routing cards to include specialized hardware to prototype their own design. Figure 1.
