IWR6843ISK: External memory interface with the IWR6843

Part Number: IWR6843ISK
Other Parts Discussed in Thread: IWR6843

Hi,

For certain applications we are interested in interfacing an external memory with IWR6843. I wasn't able to find any information on that in the forum. Can you guide if it is possible? If yes what is the maximum speed/bandwidth which can be supported using such an interface.

Regards,

Hi,

There is a serial flash that is interfaced with the IWR6843 EVM. is that sufficient?

More details on the SFLASH can be found in the link below

Hi,

Can we increase the size of SFLASH more than 8MB? We want to perform some tasks using mmwave radar, which require more memory for data storage.

If not then any other external memory interfacing is possible or not?

Attiya

Hi,

The MX25L3233F listed on the document linked in previous comment is a 32Mb part. is that sufficient for your use case?

The flash listed in the reference document are the tested part. You can choose other parts that meet the specification in the document, but keep in mind it hasn't been tested.

Charles
