  • Two additional SoC-based modules provide ease of Wi-Fi implementation

Dialog Semiconductor, a leading provider of battery management, AC-DC power conversion, Wi-Fi, Bluetooth low energy and Industrial ICs, has announced the availability of the DA16200, a highly-integrated, ultra-low-power Wi-Fi networking SoC and two modules that leverage Dialog’s VirtualZero technology to deliver a breakthrough in battery life for Wi-Fi connected battery-powered IoT devices.T

Longer battery life

The rise of various IoT products that require “always-on” connectivity with a continuous Wi-Fi connection has challenged engineers to develop solutions that don’t compromise battery life. Unlike other Wi-Fi SoCs, the DA16200 is specifically optimised to support such battery-powered IoT devices. DA16200’s VirtualZero technology enables a low level of power consumption that makes it achieve three to five years of battery life. The SoC utilizes an algorithm-driven design to provide the lowest power solution for facilitating an extended battery life, while also maintaining a continuous Wi-Fi connection.

To achieve extended range without compromising battery life, the DA16200 also features an integrated power amplifier (PA) and low-noise amplifier (LNA), offering users industry-leading output power and receiver sensitivity.

The highly integrated DA16200 runs the entire Wi-Fi system, security and networking protocol stack, eliminating the need for an external network processor, CPU or microcontroller. It contains an 802.11b/g/n radio (PHY), baseband processor, MAC, on-chip memory, dedicated encryption engine and an ARM Cortex-M4F host networking applications processor – all on monolithic silicon die.

Additional modules

Along with the SoC, Dialog has also launched two DA16200-based modules that deliver simple flexibility and easy design options for implementing Wi-Fi. Both modules include 4MB 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.

The modules are fully certified for worldwide operation, including certifications for FCC, IC, CE, Telec, Korea and SRRC. Additionally, both the SoC and modules are Wi-Fi CERTIFIED® for interoperability.

Robust security features

The DA16200 SoC and modules are equipped with industry-leading security protocols, including the latest generation hardware encryption engine and authentication standards for safeguarding against potential threats. Each of these products meets WPA/2/3 Personal and Enterprise standards and features upper layer security for TLS and HTTPs. Additionally, the SoC and modules can be securely booted and debugged and provide secure asset storage.

“Delivering Wi-Fi on a battery isn’t solely about achieving extended battery lifetime; it’s about enabling IoT developers to unlock the full potential of smart devices by delivering low-power functionality in conjunction with always-on connectivity. That’s the breakthrough the IoT market sorely needs and that the new SoC and modules provide,” said Sean McGrath, Senior VP, Connectivity and Audio Business Group, Dialog Semiconductor.

Evaluation boards and a complete software development kit (SDK) are now available for the DA16200 SoC and modules via DigiKey. The SDK includes sample applications, provisioning apps, AT command library, power management tools and more.
