Section 2Using the STK594 Top Module

2.1 Preparing the

STK500 for Use

with the STK594

Prior to using the STK594 with the STK500, it is necessary to make a few adjustments
to the STK500 StarterKit to allow for proper operation of Atmel’sAT94K FPSLIC
devices.
2.1.1 AdjustingVTARGET
for the AT94K
Devices
According to the AT94K Series datasheet, the VCC operating voltage is specified where
{VCC |3.0<V
CC = 3.6} Volts, withrespect to ground. The STK594 board requiresthat
theSTK500boardsuppliesaV
CC within the operating range for the AT94Kdevices.
Prior to using the STK594 board, it is necessary to adjust the VTARGET to a value
between 3.0 and 3.6V. For more inf ormation on adjusting VTARGET from within AVR
Studio, consultsection 5.3.5.1 of theSTK500 User Guide, available on theAtmel web
site (www.atmel.com).
Note:
It may be necessary to adjust the VDD voltage, see “Split Power Supply Supp ort”
on page 6 of this section for more information.
2.1.2 Connecting the
STK594 to the
STK500 Starter Kit
The STK594 should be connected to the STK500 expansion h eader 0 and 1. It is impor-
tant that the top module is connected in the correct orientation as shown in Figur e2-1
on page 2. The EXPAND0 written on the STK594 top module should match the
EXPAND0 written besidethe expansion header on the STK500 board.
