Wi-Fi SoC and modules for extended battery life for IoT applications

12 May 2020

Dialog Semiconductor plc has introduced an ultra-low-power Wi-Fi networking system-on-chip (SoC) and two modules For extended battery life for Wi-Fi connected, battery-powered internet of things (IoT) devices.

Wi-Fi continues to be one of the main connectivity options when it comes to IoT products such as connected door locks, thermostats and security video cameras.

The DA16200 technology enables low-level power consumption for continuously connected devices that can achieve up to a year of battery life and maybe even three to five years in some cases. The SoC uses an algorithm-driven design to extend battery life while the Wi-Fi connection is continuous.

The SoC includes an external network processor, CPU or microcontroller as well as an 802.11b/g/n radio, baseband processor, MAC, on-chip memory, dedicated encryption engine and an ARM Cortex-M4F host networking applications processor on a monolithic silicon die.

The two DA16200-based modules work with the SoC and include 4MN flash memory and all required RF components including a crystal oscillator, RF-lumped filter and either a chip antenna or a u.FL connector for an external antenna.
