(1)
I
DDIO
current is dependent on the electrical loading on the I/O pins.
(2)
The I
DD3VFL
current indicated in this table is the flash read-current and does not include additional current for erase/write operations.
During flash programming, extra current is drawn from the V
DD
and V
DD3VFL
rails, as indicated in
. If the user application
involves on-board flash programming, this extra current must be taken into account while architecting the power-supply stage.
(3)
I
DDA18
includes current into V
DD1A18
and V
DD2A18
pins. In order to realize the I
DDA18
currents shown for IDLE, STANDBY, and HALT,
clock to the ADC module must be turned off explicitly by writing to the PCLKCR0 register.
(4)
I
DDA33
includes current into V
DDA2
and V
DDAIO
pins.
(5)
TYP numbers are applicable over room temperature and nominal voltage.
(6)
MAX numbers are at 125°C and MAX voltage.
NOTE
The peripheral - I/O multiplexing implemented in the 280x devices prevents all available
peripherals from being used at the same time. This is because more than one peripheral
function may share an I/O pin. It is, however, possible to turn on the clocks to all the
peripherals at the same time, although such a configuration is not useful. If this is done, the
current drawn by the device will be more than the numbers specified in the current
consumption tables.
