CC2640R2F: Sleep mode when UART interface without SRDY &MRDY

Bhavin Parmar

Part Number: CC2640R2F

Hi,

https://e2e.ti.com/support/wireless-connectivity/bluetooth/f/538/t/813707

As per your suggetion i have used following api's to enter in sleep mode and before calling that i did UART closed and RF core closed so now current consumption reaches to 3uA to 9uA range.

UART_close( uartHandle ); /* Close UART as it will not allow to go sleep */

RF_close( rfHandle ); /* RF core need to close */
Power_releaseConstraint(PowerCC26XX_SB_DISALLOW);
Power_releaseConstraint(PowerCC26XX_IDLE_PD_DISALLOW);

I just want to know from attached power down modes in which mode CC2640R2F will enter.

Bhavin

Hi,

With the settings above you should be seeing around 1uA sleep current.

Is there something else consuming power on your board?

Hi,

No, there is just CC2640R2F based in house module only, no other circuitry are there.

Please note that we are using internal RC_OSC as clock source of this.

Hi,

Did you try the same code on Launchpads?

Thanks.

Hi,

No i cant because we are not using 32 KHz crystal in our customized module and i am using RC_OSC configuration.

I just want to know that with this power sleep APIs in which sleep mode CC2640R2F will enter from given table.
