Using 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 Starter Kit to allow for proper operation of Atmel’s AT94K FPSLIC
®
devices.
2.1.1 Adjusting VTARGET
for the AT94K
Devices According to the AT94K Series datasheet, the V
CC
operating voltage is specified where
{V
CC
| 3.0 < V
CC
= 3.6} Volts, with respect to ground. The STK594 board requires that
the STK500 board supplies a V
CC
within the operating range for the AT94K devices.
Prior to using the STK594 board, it is necessary to adjust the VTARGET to a value
between 3.0 and 3.6V. For more information on adjusting VTARGET from within AVR
Studio
®
, consult section 5.3.5.1 of the STK500 User Guide, available on the Atmel web
site (www.atmel.com).
Note:
It may be necessary to adjust the V
DD
voltage, see “Split Power Supply Support”
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 header 0 and 1. It is impor-
tant that the top module is connected in the correct orientation as shown in Figure 2-1
on page 2. The EXPAND0 written on the STK594 top module should match the
EXPAND0 written beside the expansion header on the STK500 board.
