CC1352R (PREVIEW) SimpleLink Multi-Band CC1352R Wireless MCU
The CC1352R device is a multiprotocol Sub-1 and 2.4-GHz wireless MCU targeting Wireless M-Bus, IEEE802.15.4g, IPv6-enabled smart objects (6LoWPAN), Thread, Zigbee®, KNX RF, Wi-SUN®, Bluetooth® 5low energy, and proprietary systems.CC1352R is a member of the CC26xx and CC13xx family of cost-effective, ultra-low power, 2.4-GHz andSub-1 GHz RF devices. Very low active RF and microcontroller (MCU) current, in addition to sub-μA sleepcurrent with up to 80KB of RAM retention, provide excellent battery lifetime and allow operation on smallcoin-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 RadioController (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 devicedoes not come at the expense of RF performance; the CC1352R device has excellent sensitivity androbustness (selectivity and blocking) performance.

The CC1352R device is a highly integrated, true single-chip solution incorporating a complete RF systemand an on-chip DC/DC converter.Sensors can be handled in a very low-power manner by a programmable, autonomous ultra-low powerSensor Controller CPU with 4KB of SRAM for program and data. The Sensor Controller, with its fastwake-up and ultra-low-power 2-MHz mode is designed for sampling, buffering, and processing bothanalog and digital sensor data; thus the MCU system can maximize sleep time and reduce active power.

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’sdevices into your design, allowing 100 percent code reuse when your design requirements change.

物联网(IoT)网关参考设计TIDC-01002

Sub-1 GHz Embedded Sensor to Cloud Industrial Internet of Things (IoT) Gateway Reference Design The TIDC-01002 design demonstrates how to connectsensors to the cloud over a long-range, Sub-1 GHzwireless network, which may be used in industrialsettings, such as building control and asset tracking.

This TI Design is powered through a TI SimpleLink™CC3220 processor and SimpleLink ultra-low-power(ULP), Sub-1 GHz CC13x0 and CC13x2 devices. Thereference design pre-integrates the TI 15.4-Stack partof the SimpleLink CC13xx software development kits(SDK) and SimpleLink CC3220 SDK, which are part ofthe TI SimpleLink MCU platform, providing a unifiedsoftware experience across TI low-power, wired, andwireless MCUs.

The TIDC-01002 provides a reference for creating an industrial, Internet of things (IoT) gateway that iscapable of connecting a network of wireless sensors to an enterprise cloud provider. In this referencedesign, a long-range, low-power wireless network, made up of Sub-1 GHz CC13x0 or CC13x2 devices(both are supported) that run the TI 15.4-Stack-based application, can be connected to multiple cloudservice providers, such as IBM Watson IoT®, AWS IoT, and so on. An online dashboard is provided, which allows users visualize the real-time sensor data as well as send actuation commands from anywhere inthe world using an Internet-connected device with a web browser.

This reference design provides a list of suggested hardware, schematics, and foundational software toquickly begin IoT product development. The design also provides the ability to visualize the data inside alocal network without connecting to a cloud service. The software design is created to be flexible, toenable other cloud service providers of choice.

This reference design enables IoT in numerous applications, such as building security gateways, door andwindow sensor networks, asset management and tracking, and other IoT-enabled home and industrialautomation applications.

The connection between the wireless sensor network and the cloud is made possible by the TI SimpleLinkCC3220 device on the CC3220SF LaunchPad™ development platform. On one side, the CC3220 isconnected to a Sub-1 GHz device acting as the central node in the wireless network, and on the otherside, the device is connected to a cloud service such as IBM Watson IoT or AWS IoT using Wi-Fi®. Thesetwo connections allow the CC3220 device to act as a gateway to get the sensor messages from the Sub-1GHz wireless network to the cloud and to get the actuation requests from the cloud dashboard sent backto the Sub-1 GHz wireless network.

Due to the long-range and low-power capabilities of the Sub-1 GHz sensors, this reference design may beuseful for any application that would benefit from distributed sensing. This reference design provides anexample that gives the ability to visualize or actuate tens or hundreds of sensors while only needing onegateway device, the SimpleLink CC3220, to be connected to the Internet.
