2.3.2 CC1352R: SimpleLink High-Performance Dual-Band Wireless MCU

The CC1352R device is a multiprotocol Sub-1 and 2.4-GHz wireless MCU targeting Wireless M-Bus, IEEE 802.15.4g, IPv6-enabled smart objects (6LoWPAN), Thread, Zigbee ® , KNX RF, Wi-SUN® , Bluetooth® 5 Low Energy, and proprietary systems.

The CC1352R device is a member of the CC26xx and CC13xx family of cost-effective, ultra-low power, 2.4-GHz and Sub-1 GHz RF devices. Very low active RF and microcontroller (MCU) current, in addition to sub- μ A sleep current with up to 80KB of RAM retention, provide excellent battery lifetime and allow operation on small coin-cell batteries and in energy-harvesting applications.

The CC1352R device combines a flexible, very low-power RF transceiver with a powerful 48-MHz Arm® Cortex® -M4F CPU in a platform supporting multiple physical layers and RF standards. A dedicated Radio Controller (Arm® Cortex® -M0) handles low-level RF protocol commands that are stored in ROM or RAM, thus ensuring ultra-low power and great flexibility. The low power consumption of the CC1352R device does not come at the expense of RF performance; the CC1352R device has excellent sensitivity and robustness (selectivity and blocking) performance.

The CC1352R device is a highly integrated, true single-chip solution incorporating a complete RF system and an on-chip DC/DC converter.

The CC1352R device is part of the SimpleLink™ microcontroller (MCU) platform, which consists of Wi-Fi® , Bluetooth® Low Energy, Thread, Zigbee, Sub-1 GHz MCUs, and host MCUs, which all share a common, easy-to-use development environment with a single core software development kit (SDK) and rich tool set. A one-time integration of the SimpleLink platform enables you to add any combination of the portfolio ’s devices into your design, allowing 100 percent code reuse when your design requirements change.

In this reference design, the CC1352R is used to connect to initialize the IWR1642, connect to a wireless sensor network, and transmit all people counting and tracking data to the network.
