7.5.4 Reducing Current Consumption

The F2807x 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 7-1 indicates

the typical current reduction that may be achieved by disabling the clocks using the PCLKCRx register.

• To realize the lowest VDDA current consumption in a low-power mode, see the respective analog chapter of

the TMS320F2807x Microcontrollers Technical Reference Manual to ensure each module is powered down

as well.
