CC3230SF: The current consumption of CC3230SF

kobayashi.ryosuke2

Part Number: CC3230SF

I am inquiring about the current consumption of CC3230SF.

Please let us know the peak current consumption of CC3230SF during receiving operation and peak current consumption during transmitting operation. Power values are also acceptable.

In addition, we are currently mounting and operating the CC3230SF on a prototype board, and are particularly concerned about the following.
During Wi-Fi reception operation, a peak current of about 350mA is consumed for about 1ms at 8ms intervals.
What is this current consumption? Is it possible to operate without peak current?
The receiving operation is only for DSSS method reception, and is used only for RSSI acquisition purposes.

The following is the current waveform during reception operation

Please refer to the datasheet and power management guide.

Thanks for the reply.
Any ideas to reduce current consumption during Wi-Fi reception operation?

The numbers you provide seem too high (looks like ~100mA more then datasheet number both for the RX and TX - as I guess the 350mA indicates TX e.g. sending TCP ACK) - you should look for the gap in your system. You can use our design review process to help with that (https://www.ti.com/tool/SIMPLELINK-WIFI-DESIGN-REVIEWS).

On the power management guide you can get all the details about low-power feature supported.

I guess the Long Sleep Interrupt (LSI - which allows you to sleep longer between beacon polling) is the most effective but it impacts mostly IDLE power (connection without data).

Where can I find information on low power features during Wi-Fi scanning in the Power Management Guide?

I don't know what do you mean by that. There is no specific low power feature for wi-fi scanning.

You can read more on the scanning in the programmer's guide (see chapter 4.7).
