This section describes in detail how the STK502 is used with the STK500.
2.1
Connecting the
STK502 to the
STK500 Starter
Kit
Connect STK502 to the STK500 expansion header 0 and 1. It is important that the top
module is connected in the correct orientation as shown in Figure 2-1. EXPAND0 written
on the STK502 top module should match EXPAND0 written beside the expansion
header on the STK500 board.
Figure 2-1. Connecting STK502 to the STK500 Board
Note:
2.1.1
Placing an
ATmega169 on
STK502
STK502 User Guide
Connecting STK502 with wrong orientation may damage the board.
STK502 contains both a ZIF socket, and a footprint for a TQFP package which allows an
easy way of soldering an emulator adapter directly into the STK502. Care should be
taken so that the device (or adapter) is mounted with the correct orientation. Figure 2-2
shows the location of pin1 for the ZIF socket and the TQFP footprint.

Figure 2-2. Pin1 on ZIF Socket and TQFP Footprint
Caution: Do not mount an ATmega169 on the STK502 at the same time as an AVR is
mounted on the STK500 board. Neither of the devices will work as intended.
2.2
PORT
Connectors
ATmega169 have additional ports to those available on the STK500. The ports are
located on the STK502 board. They have the same pin out and functionality as the ports
on the STK500 board. Port A to Port D are already present on the STK500 board. They
are not duplicated on the STK502.

RST
On the ATmega169 the RESET-signal and PG5 share the same pin. The “RST” is the
RESET-signal that comes from the STK500 board. Please note that it is not directly connected to the ZIF socket or the TQFP footprint on the STK502. This because the
RESET-signal on the STK500 has an pull-up resistor to VCCT which will interfere with
PG5 when used as an ordinary I/O-pin.
If RESET/PG5-pin on ATmega169 shall be used as a Reset pin, the RST and PG5 on
the PORTG /RST must be connected with a jumper. See Figure 2-5.
If the pin shall be used as an I/O-pin the jumper must be removed.

Programming the The ATmega169 can be programmed using both SPI and High-voltage Parallel Programming. This section will explain how to connect the programming cables to
ATmega169
successfully use one of these two modes. The AVR Studio STK500 software is used in
the same way as for other AVR parts as described in the STK500 User Guide.
2.3.1
In-System
Programming
Note:
The ATmega169 also support Self Programming, See AVR109 application note
for more information on this topic.
Note:
The jumper for the Reset-signal on PORTG/RST must be mounted before any
programming can take place. See Section 2.2.2.2
Figure 2-6. In-System Programming
To program the ATmega169 using ISP Programming mode, connect the 6-wire cable
between the ISP6PIN connector on the STK500 board and the ISP connector on the
STK502 board as shown in Figure 2-6. The device can be programmed using the Serial
Programming mode in the AVR Studio4 STK500 software.

Programming
Figure 2-7. High-voltage (Parallel) Programming
To program the ATmega169 using High-voltage (Parallel) Programming, connect the
PROGCTRL to PORTD and PROGDATA to PORTB on the STK500 as shown in Figure
2-7. Make sure that the TOSC-switch is placed in the XTAL position. See Section 2.6,
“TOSC Switch”.
As described in the STK500 User Guide (jumper settings), mount the BSEL2 jumper in
order to High-voltage Program the ATmega devices. This setting also applies to Highvoltage Programming of the ATmega169.
The device can now be programmed using the High-voltage Programming mode in AVR
Studio STK500 software.
Note:
See the STK500 User Guide for information on how to use the STK500 frontend software in High-voltage Programming mode.
Note:
For the High-voltage Programming mode to function correctly, the target voltage
must be higher than 4.5V.
Caution: Make sure to disconnect LCD-display from the segment pins header. Otherwise the lifetime of the LCD display may be severely reduced. See Figure 2-10.

2.5
LCD Display
STK502 includes a LCD display. It features six 14-segments digits, and some additional
segments. All in all the display supports 120 segments. The display is designed for 3V
operating voltage. See the Technical Specifications for more details on the display.
2.5.1
Connecting the
STK502 LCD to the
ATmega169
The segment-pins from the ATmega169 are located at PORTA, PORTC, PORTD, and
PORTG. For simplicity in use they are all joined together on the header labeled “Segment pins from ATmega169”. The header next to it, labelled “STK502 LCD pins” holds
all the segments-pins for the LCD-display on the STK502.
By using the 34-lead cable that comes with the STK502-kit, the two pin-headers can be
connected, allowing the ATmega169 to control the LCD-display. See Figure 2-10.
Figure 2-10. Connecting the ATmega169 to the STK502 LCD
Caution: High-voltage Programming uses PORTB and PORTD. Be sure to disconnect
any LCD-display connected to the ATmega169 during the High-voltage Programming.
Otherwise the lifetime of the display may be reduced.
Caution: When using PORTA, PORTC, PORTD, or PORTG as regular I/O ports, the
corresponding LCD-segment pins must be disconnected from the ATmega169.
2.5.2
Default Segment
Configuration
ATmega169 supports 100 segments. Thus not all of the 120 segments on the LCD-display can be shown simultaneously. Five of the 30 segment-pins on the LCD display has
to be left unconnected. The LCD-pins that are not connected are pin #: 3, 24, 30, 31,
and 32. See Technical Specifications for an overview of the excluded segments.
In order to use some of the segments on the LCD display that by default are not
included or in order to use some of the segment pins as ordinary I/O-pins, use a custom
strap between the two 34-pin headers. These to headers are lined up so they will fit in to
a 2.54 mm pitch grid for easy connecting, e.g., a experiment board on top of them.
The pin out for these two headers (Figure 2-11) can be found on the bottom-side of the
STK502-PCB or in Section 6 “Complete Schematics”.

Using Both Colons
on the Display
2-8
2528A–AVR–11/02
With the header J300 labelled “19 24” one can connect LCD-pin 24 (which is default
unconnected) to LCD-pin 19 by the use of a jumper. See Figure 2-12. The reason for
doing so is that the LCD-pin 24 has the segment “COL1” and LCD-pin 19 has “COL2”. In
applications where a clock, date etc. shall be displayed, it can be useful to control both
colons on the LCD-display. But connecting these LCD-pins will also lead to a connection
between segment (see Technical Specifications) “S5” and “3”, “S8” and “S7”, “8” and
“7”, which will in practice make them useless. See Figure 2-13 showing which segments are available on the LCD-display with the default segment configuration.

Other LCD-displays can be connected to the ATmega169, either through the header
“Segment pins from ATmega169” where all the segment pins are gathered or through
the ordinary Port-connectors PORTA, PORTC, PORTD, and PORTG.
Note:
Make sure the display is compatible with the electrical characteristics on the
ATmega169.

STK502 includes a two screw-terminal block where a sensor can be connected. The
STK502 kit is shipped with a NTC-thermistor attached to this screw-terminal. A NTCthermistor is characterised by the fact that when the temperature goes down the resistance goes up. Using a voltage divider and reading the voltage over the thermistor
through the ADC-channels on ATmega169, the temperature can be calculated. Application note “AVR064: STK502 – A Temperature Monitoring System with LCD Output”
describes the details of the application.
