Is the Advanced Low-Power Modes correct?

Post by beyonlo » Fri Feb 26, 2016 7:03 pm

Hi all.

Are there differences between information of TI and the WiPy kickstarter page:
* About the TI: http://www.ti.com/product/CC3200
---------------------
Advanced Low-Power Modes
Hibernate: 4 µA
Low-Power Deep Sleep (LPDS): 250 µA
RX Traffic (MCU Active): 59 mA @ 54 OFDM
TX Traffic (MCU Active): 229 mA @ 54 OFDM,

Maximum Power
Idle Connected (MCU in LPDS):
825 µA @ DTIM = 1
---------------------
* About the TI: https://www.kickstarter.com/projects/wi ... escription


>>> Ultra-Low Power (with WiFi still connected!)
In that part there are a table where say: "Active | Yes | 14mA"

So, what is the correct? 14mA in active mode or 59mA/229mA.

Could you clarify that, please?

Thank you.

Hello,

With WiFi active (in Station mode) and the MCU running, the average current is indeed ~14mA. During Rx there are short peaks of 59mA and during Tx peaks of 229mA so the power supply needs to be able to deliver those peak currents. If you want to calculate battery life you can use the 14mA figure.

Cheers,
Daniel

Yes, i would like to calculate the battery life.
Thank you.
