Ti's CC2652R device is a multi protocol 2.4 GHz Wireless MCU, with very low active RF and micro controller (MCU) current, sleep current less than 1 μ A and up to 80Kb ram, which can provide excellent battery life and support long-term operation of energy collection applications relying on small button batteries.

CC2652R is characterized by its support for multiple protocols, such as thread, ZigBee^®, low-power Bluetooth^® 5, IEEE 802.15.4g, IPv6 enabled intelligent object (6LoWPAN), Wi-sun^® and proprietary systems, including Ti 15.4-stack. It supports so many protocols that CC2652R devices can be used in more scenarios. The RF-BM-2652B1 module with CC2652R as the core has been successfully developed by RF-Star.

In industrial application scenarios that need to use a large number of data nodes, CC2652R supports ZigBee^® protocol, which can shorten the R&D cycle for users and improve the efficiency of user output schemes.

CC2652R supports wi-sun standard. Wi-sun technology has the characteristics of low power consumption, interoperability, easy deployment, mesh network and so on. It is widely used in smart meters, home intelligent energy management controllers and other communication devices.

CC2652R device supports not only multiple protocols, but also ble 5.0. Compared with ble 4.2, ble 5.0 has faster transmission speed, wider transmission range and lower transmission power consumption.

Ble 5.0 has twice the transmission speed, four times the transmission range and eight times the transmission efficiency. Ble 5.0 supports long-distance mode, greatly extending the communication distance, and small power can also be transmitted over long distance.

Compared with ble 4.2, the change of ble 5.0 in physical layer makes the communication distance longer. Theoretically, the effective transmission distance of ble 5.0 is 300 meters, while the former ble 4.2 is only 100 meters. But in practical application, the transmission distance of signal is also affected by the power of Bluetooth device and antenna. For example, in order to save power and increase working time, whether BL 5.0 or bel 4.2 standard is adopted, the actual transmission radius of Bluetooth audio is generally 10 meters.

Compared with ble 4.2, ble 5.0 has a higher communication rate, double the theoretical transmission rate, from 1Mbps to 2Mbps.

CC2652R can be regarded as the full blood version of CC2642R, which supports more protocols than CC2642R. In the application of ble 5.0, CC2652R supports multi protocol and the advantages of ble 5.0 will bring more reference solutions to the application of the Internet of things. RF-BM-2652B1 module with CC2652R as the core will be an indispensable choice in the application of Internet of things.

RF-BM-2652B1 is a SimpleLink multi-protocol 2.4 GHz wireless module independently developed by RF-STAR with CC2652R as the core. In addition to integrating a high-performance ARM Cortex-M4F processor responsible for application logic and an ARM Cortex-M4F processor dedicated to the RF core In addition to the M0 processor, it also has a very distinctive 16-bit low-power sensor processing core. It has 352 KB of programmable flash memory and 80 KB of ultra-low leakage RAM (SRAM). It supports wireless communication protocols such as Thread, ZigBee, Bluetooth Low Energy 5.0, Wi-SUN, and 6LoWPAN. High and low power consumption are optional, PA+LNA improves anti-interference ability and communication distance, and improves communication stability.
