Unlike its neighbor Finland, Norway in Northern Europe is not famous in the world of science and technology for its successive successes in NOKIA and Angry Birds. In the eyes of ordinary people, Norway does not have many outstanding science and technology companies except for the gradually declining Opera browser. But the fact proves that this is just your wishful thinking. In recent years, when the Internet of Things boom has swept the world, a Norwegian company has made great strides in the field of Internet of Things applications with its decades of deep accumulation in the field of low-power wireless, and has won unanimous praise from customers. This company is called Nordic Semiconductor, and their main product is the low-power wireless solution that is essential for the Internet of Things. Nordic was founded in 1983 and is headquartered in Norway. The company is mainly engaged in the IP design of mixer circuits, analog circuits, and digital circuits and the development of high-frequency short-range RF ICs. The company has also achieved outstanding results. As a wireless expert, Nordic launched 2.4Ghz products in 1998, and its 2.4GHz wireless products have established its benchmark position in the industry. Logitech, Microsoft and other well-known brands use Nordic's nRF products in their 2.4GHz products. Around 2006, Nordic and NOKIA jointly developed an ultra-low-power Bluetooth wireless technology Wibree, which can be said to be the predecessor of the currently popular BLE. Deep cultivation in the field of low power Bluetooth With decades of deep cultivation in wireless technology, Nordic combines Bluetooth low energy wireless technology - Bluetooth core specification version 4.0 to launch the first μBlue chip - nRF8001. Its low power consumption and other characteristics attracted the attention of countless manufacturers at the time, and applied this product to multiple fields. Later, the ultra-low power wireless SoC nRF51 series was launched, which took advantage of its high integration, performance, flexibility and ease of use of embedded protocol stacks to develop wireless applications on SoC to push the simplicity of Bluetooth wireless applications a big step forward. The response to these products also confirmed Nordic's achievements in the field of low-power Bluetooth. In June 2015, Nordic launched the first product of its new generation of nRF52 series ultra-low power wireless solutions, nRF52832, and redefined single-chip Bluetooth products. Pl Kastnes, Technical Marketing Manager at Nordic, said: "Due to its low power consumption, BLE Bluetooth chips occupy an important position in the field of Internet of Things. As a member of the Bluetooth Technology Alliance, Nordic's nRF52 series is designed to meet the needs of the Internet of Things." The first product in the nRF52 series of ultra-low power wireless solutions, the nRF52832 According to Kastnes, nRF52832 has the category's first 64MHz ARM Cortex-M4F processor, 512kB flash memory and 64kB RAM, best-in-class ultra-high performance, ultra-low power multi-protocol Bluetooth Smart, ANT, proprietary 2.4GHz radio with -96dB RX sensitivity, 5.5mA peak RX/TX current, and an on-chip RF balanced/unbalanced converter (RF Balun). The unique fully automatic power management system also allows designers to easily achieve optimal power consumption. nRF52832 uses advanced 55nm technology, including 6 x 6mm QFN and micro 3.0 x 3.2mm CSP package options. Kastnes said that compared with the nRF51 series, the biggest highlight of nRF52832 is the reduction of power consumption and improvement of performance. The power consumption of nRF51 series is about 8.3mA to 10mA, while the peak power consumption of nRF52832 is only 5.5mA. This is a major breakthrough, and the 64MHz ARM Cortex-M4F processor used in the nRF52 series is also a big improvement over the previous generation. The improved performance and reduced power consumption can cope with different Bluetooth requirements in the future, which is the biggest advantage of the nRF52 series. The data test also proves Manager He's point of view. According to the EEMBC 215 CoreMark score, the nRF52832 provides up to 60% more general processing power than competing Bluetooth Smart SoC solutions based on ARM Cortex-M0/M3, and gains an additional 10 times the floating point and 2 times the DSP performance with the ARM Cortex-M4F. In addition, the SoC has an energy efficiency of 90 CoreMark/mA, which is twice that of some competing solutions. In addition to the performance improvement and power consumption improvement, the two memorable points of nRF52832 are the unique touch pairing function of this series of products. We know that Bluetooth pairing is a relatively complex scenario. Nordic took this problem into consideration and specially gave the nRF52 series this touch pairing function. Specifically, by adding NFC tags, users can better realize Bluetooth pairing through NFC.
