CC1310: Are Launchpad CC1310 Rev: 1.4 and CC13-90EU compatible?

Part Number: CC1310
Other Parts Discussed in Thread: CC1190

Hello, Texas Instruments engineers.

 

I recently purchased a CC13-90 EU Launchpad by mistake, and I am in North America, so I should have purchased a CC13-90US

I have a few questions:

What are the differences between the CC13-90EU and the CC13-90US?

Can I write firmware for the CC13-90EU by configuring the RF for 915 MHz?

I have a Launchpad CC1310 Rev: 1.4 and would like to use it with my CC13-90EU. Is it possible to maintain secure RF links regardless of the characteristics of each transceiver?

 

Thank you in advance.

    Hi,

    The main difference between the EU and US versions is the SAW filter used (because the frequency bands are different) and there are some differences in the CC1190 impedance matching/filtering:


    Additionally, the antenna matching is different (again because of the different frequency bands).

    If the RF PHY settings are exactly the same then the two CC1310 devices (with/without the CC1190) will be able to communicate, but the EU CC1310-CC1190 design may have an extremely short range (or not communicate at all) because of the attenuation by the SAW filter/non-optimal impedance matching. That is not a FW difference though, so it can be used for FW development.

    You could use almost all of the PHY settings from a CC1310-only design for a CC1310-CC1190 design - the differences would be in the PA table used and DIOs used for the control signals of the CC1190.

    Regards,
