CC2652P7: Application issues.

Part Number: CC2652P7
Other Parts Discussed in Thread: CC2652P, Z-STACK

Tool/software:

Hi Team,

Please help to review the CC2652P schematic file.

This design uses a shared antenna for BT and Zigbee. Please help confirm the following questions:
1.If one of the functions is not used, can it be turned off in the software to reduce power consumption.
2. How much can power consumption be reduced by using only Zigbee and turning off Bluetooth function?
3. Is there a GPIO Assignment document and which GPIO can be configured as interrupt pins?

Hi Reed,

Are you aware of the Dynamic Multi-protocol Manager solution?

1. Yes, it is possible to use the DMMSch_setBlockModeOn API to block operation of one stack.
2. This will depend significantly on each stack settings and application operation, but you can view expected Z-Stack power consumption measurements with the SWRA625 Application Report.
3. Any GPIO is interrupt capable and can be configured for most peripherals, see more information in the Datasheet and TRM.

I have notified a HW expert to your schematic review request, and you can also submit the design to SIMPLELINK-2-4GHZ-DESIGN-REVIEWS for review.

Regards,
Ryan

Hi Ryan,

Thank you for your reply.
Have you received any results from the schematic inspection?

Hi Reed,

I am currently reviewing the schematic, but can you officially submit it for a design review so we can track it through our system? See link below.

Hi Reed,

1. For 5dBm RF front end, change the matching circuit to match the RF front end on the LP-1352P7-4 reference design (https://www.ti.com/lit/zip/swrc373).

2. For 20dBm RF front end, use http://www.ti.com/lit/zip/SWRC380 RF front end.

3. Since this design includes a 20dBm front end, follow the layout of #3 closely. Be sure to include a shield and keep all matching circuits as close to the RF pins as possible. Any deviation may lead to failing 2nd and 3rd harmonics.
