Introduction
The STK502 board is a top module designed to add ATmega169 support to the STK500
development board from Atmel Corporation.
STK502 includes connectors and hardware allowing full utilization of the new features of
the ATmega169. The Zero Insertion Force (ZIF) socket makes it easy to use of TQFP
packages for prototyping.
This user guide is a general getting started guide as well as a complete technical refer-
ence for advanced users.
The STK502 board also includes a demonstration application, and comes with two
application notes, “AVR064: STK502 – A Temperature Monitoring System with LCD
Output” and “AVR065: LCD Driver for the STK502”. These application notes explain
how to use the different modules in the device. Included in the kit is a pre-programmed
ATmega169. Insert the device in the ZIF socket and the demonstration application will
start immediately.

Section 2
Using the STK502 Top Module
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: Connecting STK502 with wrong orientation may damage the board.
2.1.1 Placing an
ATmega169 on
STK502
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.
2.2.1 PORT E/PORT F Figure 2-3 shows the pin out for the I/O port headers Port E and Port F.
Figure 2-3. General I/O Ports
Note: Port E is also present on the STK500, but only PE0 to PE2 (three least signifi-
cant bits) are accessible there. To access all Port E bits the connector on the
STK502 must be used.
2.2.2 PORT G/RST In addition to the normal Port G pins, this connector has the RESET-signal. Se Figure 2-

Figure 2-4. PORTG/RST
2.2.2.1 PG0 - PG5 These are general I/O ports connected to ZIF socket and the TQFP footprint.
2.2.2.2 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 con-
nected 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.

2.3 Programmingthe
ATmega169 The ATmega169 can be programmed using both SPI and High-voltage Parallel Pro-
gramming. This section will explain how to connect the programming cables to
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.
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
2.3.1 In-System
Programming 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.
Note: See STK500 User Guide for information on how to use the STK500 front-end
software for ISP Programming.
