II. Core Product Hardware Analysis

2.1 SiWx917M Ultra-Low-Power Wi-Fi 6 Wireless SoC

The SiWx917M is Silicon Labs’ next-generation, power-optimised Wi-Fi 6 SoC designed specifically for the IoT. It employs a dual-processor architecture that completely separates application processing from wireless communication tasks, balancing operational efficiency with power consumption control, and is specifically developed for battery-powered IoT devices requiring long battery life.

The core hardware configuration features a 160 MHz Network Wireless Processor (NWP) and an ARM Cortex-M4 core (with FPU), enabling efficient processing of wireless protocol stacks, sensor data calculations and terminal business logic. It incorporates up to 8 MB of Flash memory and high-capacity PSRAM to meet the demands of complex applications, multi-protocol stack operation and local data caching. The chip natively integrates an ultra-low-power Wi-Fi 6 (2.4GHz single-band) and Bluetooth LE 5.4 dual-mode wireless subsystem, supporting concurrent operation of multiple protocols without the need for an external RF chip, thereby streamlining the hardware architecture. It also features a dedicated sensor hub capable of independently managing peripheral sensor devices, significantly reducing the frequency at which the main MCU is woken up and further optimising the device’s overall power consumption.

In terms of power consumption design, the SiWx917M achieves industry-leading optimisation of both sleep and active power consumption. It supports multi-level power modes, including deep sleep, light sleep and fast wake-up. A cold start with a full-channel SSID scan takes just 5 seconds, with peak power consumption below 50 mA, balancing responsiveness with low power consumption and making it ideally suited for IoT terminal scenarios involving infrequent wake-ups, frequent sensing and intermittent networking. In terms of security, it features a natively integrated hardware encryption engine and supports multiple security mechanisms, including the WPA3 enterprise-grade security protocol, TLS 1.2 encryption, and PEAP/TTLS authentication, thereby mitigating the risks of eavesdropping, forgery and attacks on wireless transmissions at the hardware level.

2.2 SiWx917Y Standardised Mass-Production Wireless Module

The SiWx917Y is a standardised PCB wireless module based on a deeply integrated SiWx917M SoC. Designed for rapid mass production, low development barriers and global compliance, it addresses the pain points of traditional wireless solutions, such as complex RF debugging, lengthy certification cycles and poor mass-production consistency. Measuring just 16 mm × 21 mm × 2.3 mm, the module’s ultra-slim form factor is ideal for space-constrained products such as compact smart devices, wearable devices and micro-sensors.

The module features a highly integrated design, incorporating the SiWx917M core SoC, a 40 MHz high-precision crystal oscillator, a complete RF matching circuit and a metal shielding cover. It offers two hardware configurations—an on-board antenna and external RF pins—enabling flexible adaptation to different product structural designs. RF and electromagnetic compatibility (EMC) certifications for major global regions have been completed prior to shipment, eliminating the need for customers to carry out repeated RF debugging and compliance testing, thereby significantly shortening time-to-market and reducing R&D and mass production costs.

At the software and protocol level, it is fully compatible with the core capabilities of the SiWx917M, offering native support for Wi-Fi 6, Bluetooth LE 5.4, the Matter protocol and a complete IP network protocol stack. It supports two operating modes—standalone SoC operation and NCP coprocessing—and is compatible with mainstream hardware interfaces such as UART and SPI, enabling rapid integration with various host control platforms and offering exceptional adaptability.
