Introduction
Congratulation for acquiring the AVR® STK526 - AT90USB82/162 Starter Kit. This kit is
designed to give designers a quick start to develop code on the AT90USB82/162 and
for prototyping and testing of new designs.
1.1 Overview
This document describes the STK526 dedicated to the AT90USB82/162 AVR
microcontroller. This board is designed to allow an easy evaluation of the product using
demonstration software. This document applies to the revision B of the board.
To complement the evaluation and enable additional development capability, the
STK526 can be plugged into the Atmel STK500 Starter Kit Board in order to use the
AT90USB82/162 with advanced features such as variable VCC, variable XTAL, Parallel
Programming, and supports all AVR development tools.
It can also receive extension modules that Atmel or 3rd parties may release in future or
that customers can develop for their projects.
To increase its demonstrative capabilities, this stand alone board has several on-board
resources : USB, RS232, joystick, data-flash, LEDs.

2.2 Power Supply
The on-board power supply circuitry allows different power supply configurations.
Because the AT90USB82/162 contains an internal 3V3 regulator that can be used to
power an external circuitry, several power configurations are handled by the STK526.
The power path is represented by the figure below :
Figure 2-2 . STK526 Power Configuration
First, the board allows to drain power from three external sources, leading to four
different solutions. The selected voltage is applied to the regulator input of the
AT90USB82/162. Then the user can choose to power the MCU I/O either directly with
the primary power source (external 5V/3V3), or from the internal regulator itself (MCU
auto-power).
2.2.1 Power Supply Sources
The power supply can come from three different(1) sources:
USB connector,
JACK PWR connector (J5, See Figure 2-3),
STK500
USB powered: When used as a USB device bus powered application, the STK526 can be powered via
the USB VBUS power supply line.
JACK PWR connector: – Use the JACK outlet provided with the kit (See Figure 2-4)
– Input supply from 9 up to 15V (2) DC,
– No specific polarization (3) is required.

Notes: 1. Caution: Do not set more than one power supply source on STK526.
2. 15V is the maximum level limitation of an unidirectional transit diode.
3. There is a diode (bridge) voltage drop between the negative output of the power
supply and the STK526 “GND”. This could introduce some gap of voltage during
measurement and instrumentation.

2.2.2 Power Source Setting

Notes: 1. Caution: The STK500 has its own “ON/OFF” switch
Vcc Source
Jumper position VCC power supply value Comments View
VBUS VBUS
(4,8V to 5.2V)
This is the default configuration.
This should be used for a typical USB
device “bus powered” application.
In this mode, the STK526 is powered
directly from the USB bus, and no
other external power supply is
required.
REG 5V 5V
This configuration can be used for a
USB “self powered” device
application”.
To use this configuration an external
power supply must be connected to
J5 connector. The on-board 5V
regulator is used.
REG 3V3 3.3V
This configuration allows the STK526
to be used in a 3V range application.
To use this configuration an external
power supply must be connected to
J5 connector. The on-board 3V3
regulator is used.
STK & REG 5V Depends on STK500 VTG
setting
This configuration allows the STK526
to be used with an STK500 board.
In this mode, the STK526 power
supply is generated and configured
according to the “VTG” parameter of
the STK500 (1).
Caution : NO external power supply
must be connected to STK526 to
avoid conflict with STK500 power
supply.
