Streamlining IoT Device Development
Silicon Labs has officially launched the SiWx917Y ultra-low power Wi-Fi 6 and Bluetooth Low Energy (LE) 5.4 modules, enhancing its Series 2 platform. These modules aim to assist device manufacturers in navigating the intricate development and certification processes associated with Wi-Fi 6 devices. Built for efficiency, the SiWx917Y modules not only provide excellent wireless connectivity but also prioritize power efficiency, robust security, and a comprehensive application processor. These features collectively reduce design challenges, product size, costs, and time-to-revenue for developers.
With Wi-Fi technology advancing rapidly within the Internet of Things (IoT) landscape, the potential for innovation has surged. “Wi-Fi for IoT has evolved significantly, creating exciting opportunities for innovation. To help end device makers accelerate their full potential, we developed the SiWx917Y Wi-Fi 6 modules,” stated Irvind Ghai, vice president of Wi-Fi solutions at Silicon Labs. By offering pre-certified modules, Silicon Labs allows manufacturers to smoothly integrate advanced connectivity into their devices and focus more on unique solution differentiation while lowering development costs.
The SiWx917Y modules are particularly well-suited for low-power Wi-Fi applications across various sectors, including smart home technology, building automation, healthcare devices, industrial sensors, and asset tracking.
Advanced Features for Enhanced Connectivity
Encased in a compact footprint of 16x21x2.3 mm, the SiWx917Y modules pack substantial capabilities. They incorporate Wi-Fi 6, Bluetooth LE 5.4, an ARM Cortex-M4 application processor, a wireless network processor, abundant memory, and an extensive range of peripherals. Key features include:
– Ultra-low power Wi-Fi 6 connectivity with intelligent power management
– Dual-core architecture featuring dedicated application and wireless processors
– Support for the Matter protocol over Wi-Fi
– Integrated antenna, RF pin, and worldwide RF certifications
– Multiple operational configurations for design versatility
An innovative power management system enables connected sleep mode with current draw as low as 20μA while utilizing Target Wake Time (TWT) and maintaining a 60-second keep-alive interval. This capability allows IoT devices like smart locks, thermostats, smart cameras, and video doorbells to achieve multi-year battery life. Moreover, the integrated ARM Cortex-M4 processor provides extensive edge processing capabilities supported by substantial memory and peripherals.
The modules can operate in two modes: the SiWG917Y serves as a System-on-Chip (SoC) allowing direct execution of all application code on the module’s ARM Cortex-M4 core, while the SiWN917Y functions as a Network Co-processor (NCP) enabling application execution on a separate microcontroller (MCU), with the Wi-Fi module managing communications.
Responding to Growing IoT Demands
As the IoT sector experiences exponential growth, the demand for efficient and secure Wi-Fi solutions has sharply increased. With low-power, Wi-Fi-enabled IoT applications predicted to expand by one billion units annually, manufacturers face challenges in integrating reliable connectivity while balancing energy efficiency, security, and ease of development.
The SiWx917Y modules are now available for purchase, representing a significant advancement for manufacturers looking to enhance their IoT capabilities. For further information regarding Silicon Labs’ SiWG917Y and SiWN917Y modules, visit their website.
