ON/OFF Switch and the Power Supply Circuit
The Demo/Emulation board can be powered by an external 9VDC power supply or by on-board batteries. To
use the external power supply, connect the adapter plug into J1 located near the upper-right corner of the board.
To use batteries, install 3 AA batteries into the battery holder located on the bottom side of the board.
The On/Off switch (S4) is also located near the upper-right corner of the board. When this switch is in the ON
position:
If the external power supply is plugged in, the board is powered from the external power supply.
If the external power supply is not plugged in, the board is powered from the on-board batteries.
When the power is applied to the board, the green LED (D8) will turn on.
The power supply circuit is located in the upper-right area of the board, and there are 5 power supply outputs
with test points:
VCCA:
3.3V, powers the application analog circuit
VCCB:
3.3V, powers the application digital circuit
VCCC:
3.3V, powers supporting circuits
VCCINT:
1.2V, used for XC3250AN (U1) and VSI403LP (U3)
VCCBAT:
5V if external power supply is used, and 4.5V if the battery is used.
Powers the audio amplifier IC (U22)
