The F2838x devices provide some methods to reduce the device current consumption:
- One of the two low-power modes—IDLE or STANDBY—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. The Typical
Current Reduction per Disabled Peripheral table lists the typical current
reduction that may be achieved by disabling the clocks using the PCLKCRx
register.
- To realize the lowest VDDA current consumption in an LPM, see the
Analog-to-Digital Converter (ADC) chapter of the TMS320F2838x Real-Time Microcontrollers
Technical Reference Manual
to ensure each module is powered down as well.
