The latest 5.0 protocol, a list of major manufacturers and solutions for Bluetooth chips

Bluetooth SIG announced that global Bluetooth device shipments in 2017 were 3.6 billion! The compound annual growth rate of Bluetooth devices is 12%. Obviously, this is a very worthwhile market. At the same time, the outbreak of the consumer-grade IoT market will also promote the rapid growth of Bluetooth technology.

1. what is Bluetooth?

Bluetooth technology was originally created in 1994 by Ericsson. The goal of developing this technology is to eliminate the need to connect cables between mobile phones and PC cards, headsets, desktops and other devices.

Bluetooth uses short-wavelength high-frequency (UHF) radio waves, using frequency hopping technology to resist signal fading; fast frequency hopping and short packet technology can reduce co-channel interference and ensure transmission reliability; forward error correction coding technology can reduce far The effect of random noise during transmission; the complexity of the device is reduced by FM modulation.

2. Development of Bluetooth technology

With the advancement of Bluetooth technology, from V1.1 to V2.0 to V4.2 and the latest version of V5.0, continuous optimization and improvement. Compared with V4.2, Bluetooth 5.0 can bring twice the data transmission speed, the upper limit of transmission speed is 2Mbps; the data transmission capacity is increased by 8 times; the transmission distance of Bluetooth 5.0 is increased by 4 times. These features make Bluetooth wireless technology more suitable for IoT applications such as smart homes and wearable devices. By 2022, there will be 50 billion connected devices worldwide, and about one-third of them will be equipped with Bluetooth wireless standards.

Not only that, the rise of low-power Bluetooth BLE, the Bluetooth chip form has also undergone an important change. Faced with a large number of low-power, compact applications, chipmakers are considering integrating the functions of the main controller and RF into a single chip to form a BLE SoC.

3.Bluetooth 5.0 chip Brand

After the advent of Bluetooth 5.0 in 2016, major manufacturers began to introduce chip products that meet the new specifications. Here we have collected some Bluetooth 5.0 chips that have been released by manufacturers in the past two years, which is convenient for everyone to choose, or to discuss the product trends discovered from them.


CSR founded in 1998 in Cambridge, England. In 2002, CSR launched the "BlueCore (Bluetooth Core)" CMOS single-chip solution, and successfully reduced the price of its successor BlueCore 2-External chip, which prompted the take-off of Bluetooth products.

In October 2014, Qualcomm spent $2.5 billion to acquire CSR. The marriage of the mobile phone chip leader and the Bluetooth chip maker was seen as a "natural match." CSR has a strong backing and can resist the risks brought by many competing chip manufacturers to integrate Bluetooth technology into SoC.
