Part Number: IWR6843ISK
Other Parts Discussed in Thread: CC3351, IWR6843, , IWR6843AOP, CC2642R

Tool/software:

Hi,

Please help confirm compatibility of IWR6843 & CC3351 and if yes, share the reference design. if not, give the recommendation of combo wifi + Bluetooth connection to IWR6843

Regards,

Hi Karthick,

Could you please clarify more on what you meant by compatibility? Is it some specific interface you are looking for to interface with CC351. Or you want to know if the IWR6843ISK EVM can interface with CC351 Evaluation Module. If yes, could you please share the EVM PN; or is it mmWave radar device interfacing with CC351 chipset.

Regards

Hi Karthick,

You should be able to interface using UART and SPI. Please see below an example interfacing for IWR6843AOP with CC2642R.

Hi Karthik,

Are you designing a new board or want to use existing EVMs? We do not have any IWR6843 (IWR6843ISK) EVM with BLE + Wifi capablities.

Hi Karthik,

Then you should be able to interface using both UART and SPI.

Does the MCU in the IWR6843 supports for TCP/IP stack, which is important for wifi + Bluetooth chip to connect with?

Hi Karthick,

IWR6843 has an inbuilt Cortex R4F. I will need to check internally if it supports TCP/IP stack. Please allow me to investigate this by early next week.

Hi Karthick,

The IWR6843 (with Cortex R4F) does not support the TCP/IP stack; it will need additional companion product such as CC26XX and CC32XX to support the TCP/IP stack.
