Hi,

Recommended Operating Conditions for CC3220SFMOD are Vbat=2.3 to 3.6V. Module is not designed to be able work at 1.85V.

Hi,

Pre-regulated mode (1.85V) is supported by CC3220SF QFN chip. This mode is not supported by modules with CC3220SF manufactured by TI. At your first post you mentioned module.

At datasheet is not stated power consumption at pre-regulated mode. But I expect that this will be similar as 1st generation ( e2e.ti.com/.../1379931 ). This need to be confirmed by TI.

Hi,

The consumption will be slightly higher than what is mentioned in the post Jan pointed to, since the SF part will need the flash to be powered as well.

We recommend using 3.3V Wide Voltage mode.

Best,
Kevin

Thanks I understand that there will be more but wanted to get accurate given
Yes, I understand that you recommend 3.3V., I do not need 1.85V.
