Reducing Current Consumption

The F2837xD devices provide some methods to reduce the device current consumption:

•

Any one of the four low-power modes—IDLE, STANDBY, HALT, and HIBERNATE—could be entered

during idle periods in the application.

•

The flash module may be powered down if the code is run from RAM.

•

Disable the pullups on pins that assume an output function.

•

Each peripheral has an individual clock-enable bit (PCLKCRx). Reduced current consumption may be

achieved by turning off the clock to any peripheral that is not used in a given application. Table 5-2

indicates the typical current reduction that may be achieved by disabling the clocks using the

PCLKCRx register.

(1)

At Vmax and 125°C.

(2)

All peripherals are disabled upon reset. Use the PCLKCRx register

to individually enable peripherals. For peripherals with multiple

instances, the current quoted is for a single module.

(3)

This number represents the current drawn by the digital portion of

the ADC, CMPSS, and DAC modules.

(4)

The ePWM is at /2 of SYSCLK.
