zA free USB port on the host PC or on a self-powered USB hub
Optional: 10-15V DC/50mA power supply for powering STK600.
Quick Start
The STK600 starter kit is shipped with a device board with a ATmega2560 AVR microcontroller.
The STK600 can source power to the microcontroller trough the USB cable. Remember that the power available trough the USB cable is limited. If
your application attaches several peripherals to the STK600, you should use an external power source connected to the DC input socket on STK600.
The external power supply should be 9-15V DC with positive center connector.
The power switch turns the STK600 main power on and off. The red LED is lit when power is on, and the status LED will turn green. The green
LED beside the VTG jumper indicates that the target voltage is present.
An example application is described in the Example Application section. To evaluate the example, copy the code into a new project in AVR Studio.
Build the project (menu: Build) and program the resulting hex file to the target (menu: Tools/Program AVR)
To program the code using ISP:
zConnect a 6 lead flat cable between the two headers marked "ISP"
zAdjust target voltage from the HW settings tab. The voltage must be set in the range 1.8-5-5V.
zSelect ISP on the main tab and set ISP frequency to 200Khz or lower[1]
zProgram the application hex file from the program tab
To run the demo:
zConnect PORTB to LEDS using a 10 lead flat cable
zConnect PORTD to SWITCHES using a 10 lead flat cable

[1] The ATmega2560 has a default fuse setting that makes it run on a 1MHz internal clock. The maximum ISP frequency is 1/4 of the target clock
frequency.
Connecting the Hardware
The STK600 must be connected to a host PC with a USB cable. Connect the cable to a free USB port on the PC or on a USB hub. The USB port
must be capable of supplying 500mA. If using a USB hub, make sure it has an external power supply.
Connect the other end of the USB cable to the USB connector on STK600 sitting next to the DC jack.
Optionally, if STK600 is to be connected to external hardware that consumes more than 300mA, an external DC power supply can be connected to
the DC jack on STK600. The cable supplied with the kit can be used. Connect the center pin to the positive voltage and the cap to ground.
See Chapter 3, Target Socket System on how to set up the routing card and socket card.
Example Application: Using LEDs and Switches
Copy the code from this document into AVR Studio.
Tip: You need to adjust the include file specified at the 2nd line if you want to run the demo application on a device different from the

Chapter 3. Target Socket System
Socket System
STK600 is designed to support all AVR devices (both AVR and AVR32) with internal flash memory. A system based on socket and routing cards is
used to support different package types and pinouts on the STK600 board.
The picture below shows an STK600 with a mounted routing card and socket card.
Page 6 of 35STK600 User Guide

g
s\PAWEL\Ustawienia lokalne\Temp\~hhE369.htm

Socket Card and Routing Card
A socket card is a general card that does not have any device specific hardware. E.g. a TQFP-64 socket card can be used for all devices that comes
in a TQFP-64 package, regardless of pinout.
A routing card is a device specific card. It routes signals between the STK600 motherboard and the socket card. Note that several devices may use
the same routing card if they share the same pinout.
A set of spring loaded connectors make the connection between the motherboard, routing card and socket card. Clips or screws hold the stack of
cards together.
In addition to the socket and routing cards included in the kit, there are several add-on packs available to expand the part support for the STK600.
See the Device Support page to get an overview over the different socket and routing cards.
Selecting the correct routing and socket cards
Page 7 of 35STK600 User Guide
2008-06-20file://C:\Documents and Settin
g
s\PAWEL\Ustawienia lokalne\Temp\~hhE369.htm

Selecting the correct routing and socket card can be done by looking at the Device Support table.
Correct routing and socket card can also be found by just selecting the correct device in the STK600 programming dialog in AVR Studio. A
notification will display the correct routing and socket card to use, unless the STK600 already has the correct cards mounted. More information on
the programming dialog can be found in the Programming Dialog pages in the AVR Studio help.
N
ote that some of the devices has a part specific socket card, i.e. a routing card that has a socket. In this case there is only one card to install onto the
motherboard.
Mounting the cards
Mounting the routing and socket cards can either be done by plastic clips or plastic screw/nuts. Both sets are included in the STK600 package.
Install either the clips or the nuts to the motherboard depending on what solution you want to use.
Using clips
Motherboard
The clips should be installed from the bottom side of the STK600 motherboard. When properly installed, two plastic locking springs holds the clip
in place.
Routing card
Align the clips with the white lines on the motherboard. The routing card could now be placed above the four clips. Make sure that the routing card
has the correct orientation, i.e. the text should face upwards, and the white dot in the corner should match the one on the STK600. Press down the
routing card (i.e. compress the spring loaded connector on the STK600) and turn the clip 45 degrees in the clockwise direction so that it aligns with
the white line on the routing card. It is easiest to do two opposite clips before locking the two last.
Page 8 of 35STK600 User Guide
2008-06-20file://C:\Documents and Settin
g
s\PAWEL\Ustawienia lokalne\Temp\~hhE369.htm

Socket card
Connecting the socket card is done in the same way as the routing card. Make sure that the clips align with the white line outside the clip holes on
the routing card, then mount the socket card. The white spot on the socket card should align with the one on the routing card. Press down the socket
card (i.e. compress the spring loaded connector on the socket card) and turn the clip 45 degrees in the clockwise direction until it aligns with the
white line outside the clip hole. It is easiest to do two opposite clips before locking the two last.
Note
Always rotate the clips within the 45 degrees window. Do not turn them around, that could cause the routing card below to un-hock
from the clip.
Using screws and nuts
Motherboard
Insert the nuts into the STK600 motherboard from the bottom side. When properly installed the two locking springs should hold the nut in place.
Routing and socket card
Place the routing card above the mother board, make sure that the whit spot in the corner matches the white spot on the motherboard. The small
p
lastic taps on the ends of the spring loaded connectors should mate with the holes in the routing card. When the routing card is in the correct
p
osition, place the socket card onto the routing card with the white spot matching the one on the routing card. Make sure that the plastic taps on the
connectors on the socket card mates with the routing card as well.
Insert the four screws, and ti

Signal integrity
STK600 is designed to support a wide range of devices with different packages and pinouts. Many compromises has been taken to make this
p
ossible with one motherboard. The signal integrity is not optimised due to this. STK600 is not a reference design in any way, but a kit that serves as
socket programmer with some additional peripheral hardware to get started with the AVR. Serial communication at the highest frequencies may not
work.

The VTG voltage is the supply voltage to the target AVR microcontroller. It is connected to the AVR's VCC pin. VTG can either be generated by
STK600, or it can be supplied from an external source.
On-board VTG source
The on-board VTG source is set from AVR Studio. To use this source, the VTARGET jumper must be mounted. The on-board supply can be
adjusted from 0.9 to 5.5V in steps of 0.1V.
VTG can also be set to 0V, but due to hardware limitations, onboard generated VTG can not be set between 0 and 0.9V.
N
ote: Always check the AVR datasheet for operating voltage range before adjusting VTG.
Powering STK600 from USB
When STK600 is powered through the USB cable approximately 300 mA can be delivered to the target section.
Powering STK600 from an external DC source
If an external DC jack input is used approximately 1A can be delivered to the target section.
External VTG
If the VTARGET jumper is removed, VTG must be supplied from an external source. Connect the external source to one of the VTG pins on any of
the PORT headers. Always connect common ground (GND) when using an external VTG voltage.
When using an external source, the user must ensure that VTG is larger than any of the AREF voltages.
N
ote: The kit must always be powered when using an external VTARGET supply. If VTG voltage is supplied from an external source while the
main power switch is in the off position the kit may become damaged.
Status LEDs
VTARGET LED
A green LED next to the VTARGET jumper will be lit when there is a voltage of 0.9V or higher available on the VTG net.
STK600 Status LED
If a short circuit is detected when using the on-board VTG supply, the STK600 status LED will blink red.
Analog Reference Voltages
The AVR's A/D converter needs a reference voltage to set its converting range. STK600 can supply two of these voltages, AREF0 and AREF1.
For all tinyAVR and megaAVR devices, only the AREF0 is connected trough the routing card, whilst for xmegaAVR devices, AREF0 is connected
to the positive reference input and AREF1 is connected to the negative reference input on reference 0.
If the AREF0/AREF1 jumpers are mounted, the on-board Analog Reference Voltage sources are connected to the
target AVR’s AREF pins. The On-board Analog Reference Voltages can be adjusted from the PC software in the
range 0 to 5.5V, but not above VTARGET. The resolution and accuracy is 10mV.
The AREF0 and AREF1 generated voltages can also be connected to the analog comparator.
The target AVR’s AREF signals are accessible on the AUX header. The figure below shows the connection of the
AREF signals, the target section and the AREF sources.

e reference
When the AREF0/AREF1 jumper is disconnected, ADC reference voltage can be supplied from an external source, by
connecting to the AREF0/AREF pins on the AUX header.
When using external an source for AREF, the user must control that VTARGET is at a higher voltage level than AREF. This
can be controlled easily by reading the VTG value from AVR Studio before setting AREF.
N
OTE: The AREF0 and AREF1 voltage which are visible in the PC software are the STK600 generated voltages. Externally applied AREF voltages
cannot be read from AVRStudio.
Using the internal voltage reference
If the AVR's internal voltage reference is used, the AREF0/AREF1 jumper must be removed.
Using Aref as analog input
AREF0 and AREF1 can also be used as analog inputs to any of the ADC channels.
For tiny and mega devices, where only AREF0 is connected to the device via the routing card, AREF1 can be connected to a ADC channel by
connecting a cable from AREF1 on the AUX header and to the port pin header corresponding to the adc channel. (check the device datasheet for
which port pin header to connect to).
If the AVR's internal voltage reference, or an external voltage reference is used, the AREF0/AREF1 jumper must be removed. If this is the case,
AREF0 or AREF1 can be used as analog inputs by connecting a cable from pin 1 on the AREF0/AREF1 header to the port pin header corresponding
to the adc channel.
AREF decoupling capacitor
The routing card has a decoupling capacitor on AREF. This is marked with silkprint on the PCB. For some AVR devices the AREF pin is on a pin
which also is part of the high-voltage programming interface. On these routing cards the aref capacitor is not mounted, as it would make it
impossible to use the high-voltage programming interface. A capacitor can be soldered to achieve better noise performance. A typical value is 10nF.
The footprint for the capacitor is SMD size 0603.
Short circuit protection
The internal AREF voltage generators have a short circuit protection. If the STK600 measures the AREF0/AREF1 to be 0.3V or more below the
setpoint, AREF will be shut off. When this happens, the status LED will blink red. The AREF0 and AREF1 will also be shut down by the Master
MCU if a short circuit is detected on VTarget (in addition to shutting down VTarget). In this case, the status LED will blink red.
RESET Control
The STK600 controls the RESET signal to the target AVR. Under normal operation, the RESET line is held in an inactive, high state (pull-up to
VTG).
The RESET jumper
The RESET jumper connects the RESET pin on the target AVR to the STK600. When the RESET jumper is
mounted, STK600 controls the RESET signal. When the RESET jumper is not mounted, the RESET signal is
disconnected. This latter is useful for prototyping applications with an external reset system.
The RESET jumper must always be mounted when High-Voltage programming an AVR device. If using an external
reset system, it must allow the reset line to be controlled by the STK600 during programming.
The RESET button
STK600 has a reset button that resets the target AVR when being pushed. The button has no function if the RESET jumper is not mounted.
RESET signal on AUX header
The target AVR's RESET signal is accessible on the AUX header. This pin can be used to apply an external RESET signal. When applying an
external reset signal, the reset jumper must be removed.
12V Programming Voltage
During High-Voltage Programming, STK600 applies 12V to the AVR’s RESET line. Thus, an external reset circuit not capable of handling this
must be disconnected before High-Voltage programming the AVR.
External RESET de-coupling
When connected to an external system, there is often an external pull-up resistor and a capacitor connected to the reset line. A typical reset
connection is shown below.

If the external pull-up resistor is too strong (i.e << 4.7kOhm), STK600 may not be able to pull the RESET line low.
See also: Reset Line when programming an external target.
Port Connectors
All I/O port pins on the target AVR mounted on the STK600 are available on port pin connectors. These are labeled PORTA, PORTB, PORTC etc.
Depending to the AVR in use, different ports will be available.
The picture below shows PORTA. Here, all port pins PA0 to PA7 are available, in addition to the target voltage VTG and GND.
The other port connectors are identical, only with different signal names.
Cables can be mounted between the port connectors and the other peripherals on the board, or to external hardware.
AUX port connector
The AUX connector is located in the port connector area. The figure shows the pinout for the connector.
The following signals are available:
AREF0
Analog Reference voltage. This pin is connected to the AREF pin on devices having a single separate analog reference pin. For devices with two
AREF pins, this pin in connected to the AREF+ pin. The AREF0 voltage is controlled from the PC software if the AREF0 jumper is mounted.
AREF1
Analog Reference voltage. This pin is connected to the AREF- pin on devices having two separate analog reference pin. The AREF1 voltage is
controlled from the PC software if the AREF1 jumper is mounted.
XTAL1
The XTAL1 signal on the AVR is routed to this pin. If the CLOCK switch is set to the INT position, this pin can be used to apply an external clock
signal.
XTAL2
The AVR's XTAL2 pin. If the CLOCK switch is set to the INT position, this pin can be used for external crystal with the XTAL1 pin.
RESET
The RESET pin on the AVR is available on this pin.
32KHz
A 32kHz clock signal is available on this pin. It can be connected to a device's TOSC1 pin in order to implement a real-time clock. Place a jumper
between the 32KHz pin and the neighboring TOSC1 pin.
TOSC2 and TOSC1
For AVRs with a timer that can be clocked from an external low-frequency crystal, these two pins are available. The TOSC1 pin can easily be
connected to the AUX port's 32KHz pin (32kHz clock signal) by a jumper.

LEDs and Switches
STK600 has eight LEDs and eight switches that can be connected to I/O pins on the AVR. The LEDS and SWITCHES connectors are found in the
p
ort connector area.
LEDs
The LEDs are labeled LED0 to LED7. The corresponding pins on the LEDS header have the same labels.
The LED hardware is shown in the figure below. The transistor circuit ensures the LED brightness is independent of target voltage.
To light one of the LEDs, the corresponding pin found on the LEDs header must be pulled to GND.
To control the LEDs from the AVR, connect a cable between the LEDS header and one of the PORT headers. Use a 10-wire cable to connect to all
eight LEDs or a two-wire cable to control one or two LEDs.
Just like the PORT headers, the LEDS header has GND and VTG on pin 9 and 10. When using a 10-wire cable, make sure the pin one indication on
the cable (red wire, triangular arraow pointing on pin one) aligns to pin 1 on both the LEDs header and PORT pin header.
The I/O port connected to LEDn will not source any significant current when LEDn is driven high, but it will sink a current of approximately 18mA
when LEDn is pulled to GND.
Switches
The switches are labeled SW0 to SW7, and are available on the SWITCHES header. The switch hardware is shown below:
When pressing one of the switches, the corresponding SW pin on the SWITCHES header will be pulled low. When the switch is released, the
switch's 10k pull-up will pull the line to VTG. The 150 Ohm resistor prevents a large current to flow to ground in case of wrong wiring.
Connect a cable between the SWITCHES header and one of the PORT headers. Use a 10-wire cable to connect to all eight switches or a two-wire
cable to connect to one or two switches.
N
ote: On most AVR pins configured as input, you can enable an internal pull-up, removing the need for an external pull-up on the push button. In
the STK600 design, an external 10K pull-up is present to give all users a logical '1' on SWn when the push button is not pressed, even if the internal
p
ull-up is not enabled.

STK600 includes several clock options for the target AVR.
A switch selects between the following three options:
zProgrammable clock generator
zCrystal oscillator (with socket for a crystal)
zXTAL1 Pin tri-stated (to be used with the AVR's internal RC oscillator)
Programmable Clock Generator
The programmable clock generator is set from the PC software. The frequency can be set from 1.1kHz to 32MHz with 0.5% accuracy.
To use the programmable clock generator as clock source, set the CLOCK switch to EXT position.
Crystal Oscillator
The on-board crystal oscillator will work with ceramic resonators or crystals between 4 and 24MHz (AT-cut, fundamental, and parallel resonant
crystals). Place a crystal in the crystal socket (located next to the PROGRAM button).
To use the crystal oscillator as a clock source, set the CLOCK switch to the XTAL position.
XTAL1 Pin Tri-stated
If the target AVR run on the internal oscillator, the XTAL1 pin can be disconnected from the clock sources on STK600.
To disconnect the XTAL1 pin, set the CLOCK switch to the INT position.
Real Time Clock
The STK600 also features a 32768 Hz oscillator, which can be used to make a real time clock. The output from the oscillator is available on the
32KHz pin on the AUX header. This clock can be routed to the TOSC1 pin on the target AVR by placing a jumper between the 32KHz and TOSC1
p
in on the AUX header.
