LP-CC1311P3: powering the only MCU

Part Number: LP-CC1311P3
Other Parts Discussed in Thread: CC1311P3

Is there a way to provide a power supply only to the MCU (i.e., CC1311P3) in the launchpad? So I can do a power-consumed by the operation of my code.

Have you looked at this: https://www.ti.com/lit/pdf/swra478 ?

In here:- CC1311P3 LaunchPad (ti.com) (https://dev.ti.com/tirex/explore/node?node=A__AJQ.W4SjOquNWJ4zKRUcCw__cc13xx_devtools__FUz-xrs__LATEST)

It's written - "Support for placing the serial flash into low power mode is provided in the LaunchPad board file included with the SimpleLink CC13xx and CC26xx SDK."

And I'm figuring out how to do that.

Hi Kritank,

This means that, in our examples, the Board_init() method automatically puts the flash in low-power mode, prior to executing application code.

/*
 *  ======== Board_init ========
 *  Perform any initialization needed before using any board APIs
 */
void Board_init(void)
{
    /* ==== /ti/drivers/Power initialization ==== */
    Power_init();

    /* ==== /ti/devices/CCFG initialization ==== */

    /* ==== /ti/drivers/GPIO initialization ==== */
    /* Setup GPIO module and default-initialise pins */
    GPIO_init();

    Board_shutDownExtFlash();

    Board_initHook();
}

Regards,

Arthur
