With the rise of the Internet of Things, the market demand for low-power Bluetooth is growing. As a senior member of SIG (Special Interest Group), TI plays a leading and promoting role in the field of low-power Bluetooth. Since the release of BLE 4.0 in 2010, TI has taken the lead in launching the first-generation CC254x series of low-power Bluetooth SoCs and has continued to introduce new ones. It has successively launched the CC2640 series of Bluetooth SoCs, CC26x1/2/4 sequence wireless SoCs, and the latest fourth-generation low-power Bluetooth SoCs. Power consumption Bluetooth wireless SoC—CC2340, this series of Bluetooth wireless SoC supports Bluetooth 5.3, Zigbee and 2.4G private protocols, has excellent low-power performance and affordable price, and can be used in smart homes, medical, industrial control and automobiles, etc. field. As a third-party solution design company authorized by TI, Xinchida Technology has launched a variety of wireless communication modules for multiple series of TI SoCs for decades, and is committed to promoting the development of wireless Internet of Things.

The Bluetooth 4.0 protocol is a Bluetooth standard released by the SIG (Special Interest Group) in June 2010. It has two modes: BLE (Bluetooth low energy) can only communicate with 4.0 protocol devices, and is suitable for energy-saving devices that only send and receive a small amount of data ( Such as home electronics); BR/EDR (Basic Rate/Enhanced Data Rate), backward compatible (can communicate with 3.0/2.1/2.0), suitable for devices that send and receive a lot of data (such as headphones).
TI launched the industry's first BLE 4.0 chip - CC254x in 2010. It uses the 8051 core, has 8 KB RAM, 256 KB programmable FLASH and rich peripheral interfaces. It uses low-power technology and supports multiple energy-saving modes, making the working state And the power consumption in sleep state is very low, maximizing the use time of the device. Xinchida Technology has launched RF-BM-S01, RF-BM-S02, RF-BM-S02I, RF-CC2540A1 based on CC2540, and RF-BM-S01A, RF-BM-S02A, RF-BMPA-based on CC2541. Low-power Bluetooth modules such as 2541B1 are widely used in consumer medical, wearable and portable devices, security, entertainment, home automation and other fields, and are still being shipped today.
In 2015, Texas Instruments (TI) launched the second-generation BLE SoC (system-on-chip) - CC2640. The core of this generation of SoC transitioned from 8051 to Arm Cortex-M3 architecture, while increasing storage capacity, it supports the BLE 5 standard, and Compatible with Bluetooth 4.x version. This upgrade not only further optimizes performance and power consumption, making CC2640 suitable for IoT application scenarios that require low power consumption and small size, such as home and building automation, health care, fitness and medical equipment, wearable devices, and industrial automation. and other fields. Based on CC2640R2F, CC2640R2L and CC2640R2F-Q1 chips, Xinchida Technology has launched a variety of serial to Bluetooth transparent transmission modules, including RF-BM-4044B2, RF-BM-4044B3, RF-BM-4044B4, RF-BM-4044B5, RF-BM-4077B1, RF-BM-4077B1L, RF-BM-4055B1L and RF-BM-4077B2, etc. With its excellent radio frequency performance, low power consumption, stability, transmission distance and support for standard serial port transparent transmission, it has been recognized by many industry customers and has been widely used in new energy vehicles, charging piles, battery swap stations, and BMS fields. The RF-BM-4044B4 module has a tiny size of only 8 mm × 8 mm and is favored by customers in scenarios where product size is required, such as portable medical equipment.
In 2019, TI launched the third generation CC26x1/2/4 products, which support BLE Mesh networking and positioning functions. It also has multiple protocols including Zigbee, Thread, Matter, etc., which greatly enriches the product line; it also launched at the same time CC1352 series dual-band multi-protocol wireless SoC can support both Sub-1 GHz and 2.4 GHz dual-band, including Thread, Zigbee, BLE 5.2, IEEE 802.15.4g, 6LoWPAN, MIOTY, Wireless M-Bus, Wi-SUN, KNX RF , Amazon Sidewalk, proprietary systems, SimpleLink™ TI 15.4- Stack (Sub-1 GHz) and other protocols. Compared with the CC2640 series, the CC2642R, CC2652, and CC1352 series not only have improved transmission power range, but also further increased RAM and FLASH storage resources. The main parameter comparison and the module information launched by Xinchida Technology for each sequence are shown in Table 1. , due to its low power consumption, high performance and multi-protocol characteristics, it can be used in the Internet of Things (IoT), smart homes, smart buildings, medical equipment, energy management, security systems, industrial automation and other fields.

When it comes to multi-protocol, we have to say DMM. DMM is the dynamic multi-protocol manager. It is a software module that enables a single radio to run multiple wireless protocols at the same time by switching between multiple wireless protocols in real time. It is also called "time division". Multiplexing,” in which a radio switches between two protocol stacks by changing settings, channels, and other parameters. DMM may modify the scheduling sequence of RF commands according to the limitations of the protocol stack and user applications. By switching between protocol stacks in real time, multiple wireless protocols can be run simultaneously on one MCU. Xinchida Technology launched the RF-BM-2642B1/B2 based on CC2642R. It has powerful resource configuration and supports Bluetooth 5.1 AoA positioning. It can be applied to new energy vehicle Bluetooth PEPS. The RF-BM launched based on CC2651R3 and CC2652P/P7/R/R7 -2651B1, RF-BM-2652B1, RF-BM-2652B2, RF-BM-2652P1, RF-BM-2652P2, RF-BM-2652P2I, RF-BM-2652P3, RF-BM-2652P4, RF-BM-2652P4I , RF-BM-2652P7 and other multi-protocol wireless modules provide a variety of antenna forms for users to choose from, and reserve a wealth of general IO to facilitate customers to independently develop multi-protocol communication wireless products.
