USB powered: When used as a USB device bus powered application, the STK526 can be powered via
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).
The power supply can come from three different
the USB VBUS power supply line.
