CC2642R: BT5 capable?

David C

Part Number: CC2642R
Other Parts Discussed in Thread: CC2640R2F

Hello,

We’ve been studying both the CC2640R2F and the CC2642R as part of our BT5 study. We’ve been under the impression that the CC2642R has two new features that will make it completely BT5 capable… the additional flash for stack support… and the coded phy in the radio for long range.

We assume the 2640R2F will be mostly BT5, but not completely due to the lack of these features. Is this a correct assumption? Do both chipsets actually have the coded phy and the difference is just flash size?

Regards,

David

Hey David!

Yes, both have coded (long range) PHY and have support for the other BLE 5.0 features such as high speed (2M) PHY and advertisement extensions.
The main difference between the devices as you have mentioned is the flash size. More memory is available on the CC2642R with an increase of non-volatile memory from 275kB to 608kB. This breaks down into 352kB Flash memory + 256 KB ROM. RAM has also increased from 28 kB to 80 kB. The increase in flash will allow things such as having larger applications and more simultaneous connections.
