1. Caution: The STK500 has its own “ON/OFF” switch
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.
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.
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.
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.
