Table 6-4. TMS320C2802, TMS320C2801 Current Consumption by Power-Supply Pins at 100-
MODE TEST CONDITIONS
The following peripheral clocks
are enabled:
• ePWM1/2/3
• eCAP1/2
• eQEP1
• eCAN-A
• SCI-A
• SPI-A
• ADC
Operational
(ROM)
• I2C
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:
• eCAN-A
IDLE
• SCI-A
• SPI-A
• I2C
STANDBY Peripheral clocks are off.
Peripheral clocks are off.
HALT
Input clock is disabled.
(1) I current is dependent on the electrical loading on the I/O pins.
DDIO
(2) I includes current into V
DDA18
clock to the ADC module must be turned off explicitly by writing to the PCLKCR0 register.
(3) I includes current into V
DDA33
(4) TYP numbers are applicable over room temperature and nominal voltage.
(5) MAX numbers are at 125°C and MAX voltage.
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.
