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 Inserti on Force (ZIF) so cket makes it e asy to use of TQFP packages for prototyping.
This user guide is a general getting started guide as well as a complete technical refer­ence 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 mo dules in the device. Included in the kit is a pre- programme d ATmega169. Insert the device in the ZIF socket and the demonstration application will start immediately.

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

2.1.1 Placing an ATmega169 on STK502

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.
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 th e correct orientati on. Figure 2-2 shows the location of pin1 for the ZIF socket and the TQFP footprint.
STK502 User Guide 2-1
Rev. 2528A–AVR–11/02
Using the STK502 Top Module
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 pr esent on th e STK500 board . They are not duplicated on the STK502.

2.2.1 PORT E/PORT F Figure 2-3 shows the pin out fo r the I/O port headers Port E and Port F.

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-

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 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
the PORTG /RST
/PG5-pin on ATmega169 shall be used as a Reset pin, the RST and PG5 on
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 Programming the ATmega169

2.3.1 In-System Programming

The ATmega169 can be programmed using both SPI and High-voltage Parallel Pro­gramming. 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 an y
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 STK50 0 board and the I SP connector on the STK502 board as shown in Figure 2-6. The device can be prog rammed 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.

2.3.2 High-voltage Programming

Figure 2-7. High-voltage (Parallel) Programming
To program the ATmega169 using High-v oltage (Parallel) Programm ing, connect the PROGCTRL to PORTD and PROGDATA to PORTB on the STK500 as shown in Fig ure 2-7. Make sure that the TOSC-switch is place d in the XTAL position. See Sec tion 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 device s. 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 front-
end software in High-voltage Programming mode.
Note: For the High-voltage Program ming mode to f unction correctly, t he target volt age
must be higher than 4.5V.
Caution: Make sure to disconnect LCD-disp lay from the se gment pins head er. 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”. Th e header ne xt to it, la belled “STK 502 LCD pins” ho lds all the segments-pins for the LCD-display on the STK502.
By using the 34-lead cable that come s with t he STK5 02-kit, the two pin-he aders can b e 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 ATm ega169 during th e High-voltage Progra mming. Otherwise the lifetim e 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. Th us not all of the 1 20 segme nts on the LCD-di s­play can be shown simultaneously. Five of the 30 se gment-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 head ers (Figure 2-11) ca n be found on the bottom-s ide of th e STK502-PCB or in Section 6 “Complete Schematics”.

This hardware configuratio n will give a certain bit-mapping between t he bits in the ATmega169 LCDDRx Register and the segments on the STK502 LCD. See Section 4.1 “STK502 LCD Bit Mappings”

2.5.3 Using Both Colons on the Display

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.

Note: Make sure the display is compatible with the electrical characteristics on the
ATmega169.

2.7 Sensor Figure 2-16. NTC-thermistor

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.
