All PWM pins are toggled at
100 kHz.
All I/O pins are left unconnected.
Data is continuously transmitted
out of the SCI-A, SCI-B, and
eCAN-A ports. The hardware
multiplier is exercised.
Code is running out of ROM with
3 wait-states.
XCLKOUT is turned off.
XCLKOUT is turned off.
The following peripheral clocks
are enabled:

IDLE 75 mA 90 mA 500 μA 2 mA 5 μA 50 μA 15 μA 30 μA

STANDBY Peripheral clocks are off. 6 mA 12 mA 100 μA 500 μA 5 μA 50 μA 15 μA 30 μA
Peripheral clocks are off.
HALT 70 μA 80 μA 120 μA 5 μA 50 μA 15 μA 30 μA
Input clock is disabled.
(1) I
DDIO
current is dependent on the electrical loading on the I/O pins.
(2) 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.
(3) I
DDA33
includes current into V
DDA2
and V
DDAIO
pins.
(4) TYP numbers are applicable over room temperature and nominal voltage.
(5) 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.
