This technical reference manual provides information about how to use the CC13x2 and CC26x2 SimpleLink™ ultra-low power wireless microcontroller (MCU). The CC26x2 and the CC13x2 device platforms share the same MCU architecture and most of the peripherals. The radio in the CC26x2 device operates in the 2.4 GHz ISM frequency band, while the radio in the CC13x2 device is designed for use in the Sub-1 GHz frequency bands. The CC1352 device is a multi-band wireless MCU and can operate both in the Sub-1 GHz and 2.4 GHz bands. This document covers the whole platform of devices, so refer to the individual device data sheets for supported modules and features.
