on the
AT91M42800A
JP1 is used to boot standard or user programs. For standard operations, set it in the
STD position.
JP8 is used to select the core power supply of the AT91M42800A. Operations at 2V are
not supported on the current silicon.
For more information about jumpers and other straps, see Section 5.
DC power is supplied to the board via the 2.1 mm socket (J1) shown in Figure 2-2. The
polarity of the power supply is not critical. The minimum voltage required is 7V.
A battery is supplied on the AT91EB42. It supplies all on-board devices in the same way
that the external DC power operates. A battery fast-charge controller is provided on-
board with a fast-charge indicator (D28), as shown in Figure 2-1.

The board has a voltage regulator providing +3.3V. The regulator allows the input volt-
age to range from 7 V to 12V. When you switch the power on, the red LED marked
POWER lights up. If it does not, switch off and check the power supply connections.
The board is designed to generate the power for the AT91 product, and only the AT91
product, through the jumpers JP5 (V DDIO ) and JP8 (V DDCORE ). This feature enables mea-
surements of the consumption of the AT91 product to be made.
See Section 5 for further details.
