The F28P65x 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 TMS320F28P65x
Real-Time Microcontrollers Technical Reference Manual to
ensure each module is powered down as well.
