Using the STK594 Top Module

2.1Preparing the STK500 for Use with the STK594

2.1.1Adjusting VTARGET for the AT94K Devices

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.

According to the AT94K Series datasheet, the VCC operating voltage is specified where {VCC 3.0 < VCC = 3.6} Volts, with respect to ground. The STK594 board requires that the STK500 board supplies a VCC 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 VDD voltage, see “Split Power Supply Support” on page 6 of this section for more information.

2.1.2Connecting 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.
