Hi pixbroker,

For roadmap details, you will have to contact your local TI sales representative.

Great, www.ti.com/.../CC2640R2F looks very good, WLCSP and BT5. Can we assume that CC2640R2F in QFN packages is pin-for-pin compatible with CC2640? i.e. can CC2640R2F be used as a drop in replacement for this footprints?

Could you enumerate all differences to CC2640 one should be aware of for system design?

Hi,

Yes, the CC2640R2F is pin for pin compatible with CC2650/CC2640 QFN packages. As of press time, the CC2640R2F is in Preview status; however, the data sheet is also available at the product link.

Best wishes

Hi Pixbroker,

The only difference is that we have moved more of the BLE Stack into ROM which frees up Flash for user application. See table 3-2 in the datasheet for details.

Cheers,
Fredrik

Would a bim/stack/app image build with BLE Stack 2.01 for CC2540 work without changes on CC2640R2F? specifically, if we used Off Chip OAD on CC2640, the first and last page of flash cannot be changed, and therefore the stack in ROM cannot be used. Would this image still work on CC2640R2F?

Hello,

I believe you mean "bim/stack/app image build with BLE Stack 2.01 for CC2640 work without changes on CC2640R2F"

A new SDK will be published to support the CC2640R2F and will include a guide for migrating your existing BLE-Stack v2 CC2640/CC2650 application to this SDK. In general, the BLE-Stack APIs and application framework are mostly the same; however, due to changes to the Flash/ROM memory map layout, you cannot use the same binary firmware image. Relative to CC2640 in an off-chip OAD configuration, only the BIM sector (4kB) is required to be reserved. The RTOS can be built in ROM and the first page is not required to be reserved. This will yield ~ 12kB flash savings in an equivalent off-chip OAD configuration. There are additional improvements in the memory utilization that provide additional flash memory for your application in CC2640R2F beyond the OAD improvements.

Just to update the thread, the SIMPLELINK-CC2640R2-SDK_1.00.00.22 SDK is available for download now.

This SDK is essentially the BLE Stack 3.0? Will this also work on CC2640 or only CC2640R2?

BLE Stack 3.0 is for CC2640R2F only,

Cheers,
Fredrik
