7510A–AVR–08/05

The STK520 board is a top module de signed to ad d AT90PW M family suppo rt to the
STK500 development board from Atmel Corporation.

The STK520 includes connectors and hardware allowing full utilization of the new fea­tures of th e AT90 PWM , whil e th e Ze ro I nser tio n For ce (Z IF) soc ket allo ws eas y t o use of
SO24 & SO32 packages for prototyping.

This user guide ac ts as a gen eral ge tting st arted gui de as wel l as a compl ete tec hnical
reference for advanced users.

Notice that in this guide, the word AVR is used to refer to the target component
(AT90PWM2, AT90PWM3...)

Using the STK520 Top Module

2.1 Connecting the STK520 to the STK500 Starter Kit

Figure 2-1. Connecting STK520 to the STK500 Board

Connect the STK520 to the STK500 expansion header 0 and 1. It is important that the
top module is connected in the correct orienta tion as show n in Figure 2-1 . The
EXPAND0 written on the STK520 top module should match the EXPAND0 written
beside the expansion header on the STK500 board.

Note: Connecting the STK520 with wrong orientation may damage the board.

2.1.2 Placing an AT90PWM2 on the STK520

Caution: Do not mount an AT90PWM3 on the STK520 at the same time as an AVR is

mounted on the STK500 board or at the same time as an AT90PWM2 is mounted on the
STK520 board. None of the devices might work as intended.

2.2 Programming the AVR

2.2.1 In-System Programming

The AVR (AT90PWM2, AT90PWM3...) can be programmed using both SPI and High­voltage 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
Note: The AT90PWM3 also support Self Programming, See AVR109 application note

for more information on this topic.

Figure 2-4. In-System Programming

To program the AT 90PWM3 us ing ISP Programm ing mode , connect t he 6-wire cable
between the ISP 6PIN connec tor on the STK500 boar d and the ISP connector o n the
STK520 board as shown in Figure 2-4. 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.
