Atmel STK500 - Manual (Page 3)

Getting Started
This section describes how to connect the STK505 onto the STK500, and
connect cables to different peripherals.
Hardware Overview
The STK505 is divided into two colored sections: the green section that supports
the ATtiny24 and the blue section that supports the ATtiny26.
Note: Only one AVR device should be inserted in the sockets at a time.
ZIF socket
The ZIF socket is for the ATtiny24, in soic package.
Pin1 on the socket is indicated with the white triangle beside the lower right
corner.
DIP socket
The DIP socket is for the ATtiny26.
Pin1 on the socket is indicated with the white triangle beside the lower right
corner.
Low voltage programming connectors
The AVR can be programmed in serial mode by using a 6-pin cable between the
ISP6PIN on the STK500 and the SPROG headers on the stk505.
High voltage programming connectors
The ATtiny26 can be programmed in parallel high voltage mode by using 10-pin
cables between STK500 and STK505.
The ATtiny24 can be programmed in serial high voltage mode be using 10-pin
cables between STK500 and STK505.
Port configuration switches
The XTAL1, XTAL2 and the reset pin on both ATtiny24 and ATtiny26 can also be
used as regular I/O port pins when not used as clock inputs or reset.
The pin configuration switches connects the pins to different components/signals
dependant on their usage.
This is described in more detail in the chapter Clock Sources and Reset
Crystal sockets
The clock crystal sockets are placed close to each target socket to make it
possible to use high frequency crystals.
When crystals are used to generate the target clock signal the clock selection
switch must be in position "XTAL".
