As the Internet of Things spreads, a variety of applications require connectivity, driving wireless microcontroller developers to develop more processing power with a variety of connectivity options and ultra-low power components. Whether for the consumer market or the Internet of Things The cost-effectiveness of the edge-driven microprocessors is also a driving factor, as well as the number of components and the size of the product, so engineers are not afraid to develop low-cost, high-performance microcontrollers that offer a variety of connectivity options. According to New Electronics Reported that Redpine Signals, one of the first to introduce 802.11n chipsets, was launched in 2001. In 2013, the company introduced the first wireless protocol suite for multi-protocol IoT applications and launched WiSeConnect and WiSeMCU at the end of 2017 Dhiraj Sogani, vice president of marketing for Redpine, believes that there is a huge market for wireless microprocessor modules and all devices will need connectivity, not only locally but also locally Cloud.But to master this huge market is not easy, Cypress senior marketing director Jack Ogawa said The pre-market is highly fragmented and needs to be covered in a wide range of applications, and is still growing rapidly as it has not yet established what is state-of-the-art technology. Redpine's WiSeMCU, WiSeMCU, claims to be the lowest-power, multi-protocol wireless MCU on the market today The ARM Cortex-M4F is based on a design that runs up to 180MHz with up to 180MHz clock speeds and offers dual-band 802.11abgn Wi-Fi, Bluetooth 5 and 802.15.4 options, with 802.15.4 for Thread or ZigBee. In the lowest power mode , WiSeMCU power consumption per MHz frequency only 12uA, Sogani said most of the Internet of Things are set to sleep for a long time, only to wake up when the data transmission, battery-powered devices if you want to extend the life expectancy, it is necessary Reduce the standby current. Ogawa pointed out that low power consumption, more powerful processing power and embedded security components for IoT applications is important, but also to get the balance between sleep power consumption and work efficiency. Cypress IoT Business Unit According to Brian Bedrosian, vice president of marketing, customer requirements fall broadly into three categories: ultra-low power but high performance, more processing power and flash memory / random access memory , And high-performance microcontrollers with high-frequency memory (300 MHz), high-capacity memory, wireless (such as 802.11ac) networking, and analog controllers that operate at a fraction of the operating frequency. Edge processing drives computing power requirements and Sogani notes that many operations are performed at the edge Processing, which has an important impact on power consumption.Modulation program although suitable for some applications, but wearable devices usually can not enjoy such a luxury, like the Oura Ring smart ring will use Cypress's PSoC6 products to deal with biometric sensor Receive data and provide Bluetooth low energy (BLE) connection. Oura Health CEO Petteri Lahtela said Oura Ring needs more long-lasting battery life, more processing power and advanced sensors, and stylish and comfortable appearance, the Cypress Helped us meet these requirements and show more possibilities for wearing health products.
