For the migration of CC26x0 devices to the CC2652R7 device, please see the Hardware Migration From CC26x0 to CC26x2R guide. The CC2652R7 is a memory upgrade of the CC26x2R device. The CC2652R7 device has 144 kB of RAM and 704 kB of flash. The two devices are pin to pin compatible and a PCB design made for the CC26x2R device can be reused for the CC2652R7 device. It should be noted that for applications requiring a slow clock accuracy of < +600 PPM (such as Bluetooth Low Energy applications), an external 32-kHz slow clock is required for use with the CC2652R7 device. The only other update to the Build-of-Material (BOM) required is the Wireless MCU.
