The AM13E23x devices provide some
methods to reduce the device current consumption:
- One of the three low-power
modes—SLEEP, STOP 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 and
pulldowns on pins that assume an output function.
- Each peripheral has an
individual power enable bit ( PWREN_MCPERIPH or PWREN_SYSPERIPH). Reduced
current consumption may be achieved by disabling the power 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 power using the PWREN_MCPERIPH or
PWREN_SYSPERIPH register, see the Power Management and Clock Unit
(PMCU) chapter of the AM13E230x
Microcontrollers Technical Reference Manual.
- To realize the lowest VDDA
current consumption in an LPM, see the Analog-to-Digital Converter (ADC)
chapter of the AM13E230x
Microcontrollers Technical Reference Manualto
ensure each ADC module is powered down as well.
