The two microcontrollers both use a single-cor software development kit (SDK). They are low-power wireless microcontrollers, and can transmit and receive radio frequency signals at a greater distance.

The two devices have lots in common, but they are different in some aspects. For instance, CC2640R2F supports BLE 5.0 protocol, while CC2640R2L supports BLE 5.1 protocol. CC2640R2L doesn’t have a sensor controller engine, which makes it cheaper than CC2640R2F but more suitable in the basic transparent transmission application. From that, we can say that CC2640R2L is a lower-cost version of CC2640R2F.
