Recently, Silicon Labs (also known as "Core Technology") announced the launch of a new Bluetooth®-SLR system (SOC) solution, perfectly combines market-leading security, wireless performance, energy efficiency, software tools and protocol stacks to meet large quantities, Market demand for battery-powered Internet access products. Its EFR32BG22 (BG22) SOC extends Silicon Labs existing secure, ultra low power Wireless Gecko Series 2 platform, providing developers with optimized Bluetooth connection solutions, supporting new Bluetooth 5.2 specification, Bluetooth, Bluetooth Mesh.
According to Bluetooth Sig, the annual total shipments of the Bluetooth equipment will increase by 26% (4 billion in 2019 to 5.4 billion), and 90% of Bluetooth devices support Bluetooth. Low Energy. Safe connection and extremely low power consumption will be the basic requirements of these Internet of Things devices. Silicon Labs designed BG22 SoC to meet these requirements, as well as to address billions of Bluetooth networking equipment in the next few years.
The BG22 series combines the optimal ultra-low emission and receiving current (3.6 mA at 0 dBm; receiving 2.6 mA) and high performance, low power M33 core (operating current 27 μA / MHz; sleep current 1.2 μA) Provide industry-leading energy efficiency, extending the life of the button battery to ten years. Target applications include Bluetooth Mesh low-power nodes, smart door locks, personal healthcare and fitness equipment. SOC's Bluetooth reaching angle (AOA) and leaving angle (AOD) function and within 1 meter orientation accuracy also benefit from applications such as asset tracking labels, beacons, and indoor navigation.
The new product portfolio provides three Bluetooth SOC products options, which are designed to meet smart home, consumer, commercial and industrial Internet applications (including those who need multi-year battery life) to price / performance.
· EFR32BG22C112 SOC is suitable for large-scale, cost-sensitive applications, support 1 Mbps and 2 Mbps Bluetooth PHY transmission, 38.4 MHz ARM® Cortex®-M33 core, 18 GPIO and 352 KB flash memory, 0 DBM transmit power and industry leading - 99 DBM Receive Sensitivity (1M PHY).
· EFR32BG22C222 SOC is suitable for applications that require more computing power (with 76.8 MHz M33 core), more I / O (26 GPIO) and higher transmit power (+6 dBm).
· EFR32BG22C224 SOC provides IQ sampling capabilities, suitable for targeting applications, and supports 125 KB and 500 KB Bluetooth Low Energy Coded PHY to increase reception sensitivity to -106 dBm. The SOC also increases the operating temperature to +125 ° C and expands the flash to 512 KB to support applications that require the function or low power Bluetooth Mesh node.
Matt Johnson, General Manager of Senior Vice President of Silicon Labs, said: "As a leader of the Low Power Wireless Technology, we have greatly enhanced services for existing and continuous development of Bluetooth markets. Our secure Bluetooth solutions Make our customers to reduce BOM cost, power consumption and listing time. We took the lead in launching Bluetooth Mesh and Bluetooth 5.1 functionality, and we will continue to lead the market through innovative technologies including Bluetooth 5.2. Our The new BG22 SOC enables developers to obtain appropriate balance at low cost, thereby helping to promote Bluetooth in a wide variety of Internet of Things products. "
Silicon Labs provides an optimized security level through a cost-effective Bluetooth SOC solution. One of the most severe challenges that the Internet of Things developers is today is to ensure that the connected devices operate only true credible firmware, while BG22 SOC has a trusted root of Silicon Lab (SECURE LOADER). The secure boot function is simple, and efficiently meets this demand. SOC supports full failure analysis by allowing developers to debug issues without erasing flash memory, because the software itself may also be one of the root sources. Developers can implement this goal with security debugging with lock / unlock encryption feature of Silicon Labs.
