Introduction
1.1 AVR STK100
Starter Kit
The STK100 Starter Kit is designed to support the AVR Microcontroller from Atmel Cor-
poration. The system will help tiny AVR users to get started designing with AVR
Microcontrollers.
The STK100 incorporates an In-System Programming unit and an applications board.
For late breaking news and any manual errata always check the README.TXT file
included with the software or check the Atmel web site for any updates.
1.2 Device Support The system software currently has support for the following devices.
■AT t i n y 1 0
■AT t i n y 1 1
■AT t i n y 1 2
■AT t i n y 1 5
■AT t i n y 2 2
■AT t i n y 2 8
■AT90S2343
Upgrades for new devices will be available via the Internet at www.atmel.com.

Getting Started
2.1 Unpacking the
System
You will find the following items in the pack:
■STK100 main board
■1 disk set
■Parallel/printer port cable
■ATtiny11 sample + AT90S2343
■Atmel CD-ROM
2.2 System
Requirements
The minimum computer hardware and software requirements are:
■80486 processor or above
■16 MB RAM
■2 MB free hard disk space
■Windows 95/98 or Windows NT
2.3 Power Supply 9.5 - 15-volt DC power supply with 3.5 mm barrel connector, center positive or 7 - 13-
volt AC power supply with 3.5 mm barrel connector.
Note: If the regulator or other IC runs too hot, reduce the input voltage. The specially
formulated ink used on the STK100 will turn darker if subjected to heat to indi-
cate hot spots. It will turn lighter when the heat source is removed.
2.4 Connecting the
System
The system has two separate connections to the PC either of which may be used for
running or programming Tiny AVR devices on the STK100. The connectors for serial
and parallel port are next to each other on the STK100 board.
The two connections are serial 9-pin “D” connector connecting to the serial port or paral-
lel 25-pin “D” connector connecting to the parallel/printer port. The programmer software
must be configured for the correct connection. This is described in Section 6, “How to
Use the Software”.
Note that in order to update the internal firmware on the STK100 for new device support,
the system must be connected to the parallel port.

Getting Started
2-2 STK100 Starter Kit User Guide
Updates will be added to the Atmel web site as new parts become available.
A parallel port cable is supplied with the system to allow this port to be used for
upgrades. If you prefer to use the serial port, a straight-through serial cable is required.
Do not use a null-modem cable with crossed connections.
The software must be configured for either serial or parallel port operation, and the
correct port chosen: LPT1, COM1, etc. See Section 6, “How to Use the Software”for
details.
Please read the next section, “Hardware Description”, before using the programmer in
STK100.

Device and Jumper Information
Please refer to Figure 9-2, “Targets and Interfaces Schematic”, found in Section 9,
“Appendix A –STK100 Schematics”.
The system has four sockets for devices:
■28-pin socket
■20-pin analog socket
■8-pin digital socket
■8-pin analog socket
These sockets have been configured to accept all of the current and future AVR Tiny
devices. Please choose the correct socket for the device to program.
The STK100 features two types of programming. It will use either low-voltage In-System
Programming (ISP) or high-voltage parallel programming, depending on the part. There-
fore, it is essential that the user inserts the device into the correct socket and chooses
the correct device type from the programming menu on the PC. Failure to do so may
result in damage to the device and possibly the system.
4.1 Device
Orientation
Before programming a device using the programming module, the device must be
inserted correctly into the programming unit. The AVR device itself has an arrow printed
on it, which points towards pin 1 of the device. Below are the three types of sockets and
their orientation.
