1 Differences Between CC2640R2F and CC2640R2LCC2640R2L is the latest generation of ultra-low power wireless MCUs for 2.4 GHz operation from TexasInstruments. The CC2640R2L supports Bluetooth® low energy as well as proprietary RF.Please see the table below that highlights the major differences between the two devices:
2 PCB Design and LayoutFrom a package point of view, the corresponding packages of both devices are pin to pin compatible and a PCBdesign made for CC2640R2F can be reused for the CC2640R2L.Also, the CC2640R2 Launchpad supports both CC2640R2F and CC2640R2L devices in 7x7 packages
3 RF Compliance and Certification Although CC2640R2L is similar to CC2640R2F from an RF and pin compatibility perspective, a new regulatorycompliance certificate may be required if a PCB design is reused in production for the other device. This needsto be verified with an accredited test house, which needs to be made aware of the update to the BOM.
To obtain a waiver (if applicable) for drop in replacement, the customer may have to file an amendment to theregulatory authority notifying them of the differences between the two devices showing no RF performanceimpact.
If RF performance is impacted, a recertification may be required depending on the rules and regulation of thegoverning authority.
RF certification of the customer’s application and end equipment is the customer’s responsibility. The customeris solely responsible for the design, validation, and testing of its applications as well as for compliance with alllegal and regulatory requirements concerning its applications. Industry best practices generally require that thecustomer and their test house conduct qualification tests on actual applications taking into account possibleenvironmental and other conditions that the customer’s application may encounter. TI recommends consultingwith the accredited certification test house for further regulatory requirements.
4 Summary A PCB designed for the CC2640R2F can be reused for the CC2640R2L, as the devices (in the 7x7 and 5x5QFN package) are pin to pin compatible. However, a recertification may be required if the RF performancemeasured is different as a result of the replacement.
