ATWILC1000

The ATWILC1000 is a low-power, single-chip Wi-Fi solution designed for embedded applications requiring wireless connectivity. It integrates a 2.4 GHz IEEE 802.11 b/g/n radio transceiver with a built-in baseband processor and supports data rates up to 72 Mbps, making it suitable for IoT devices, smart home systems, and industrial sensors. The device operates in the globally available 2.4 GHz ISM band and features an efficient power management system that enables extended battery life in portable applications. This Wi-Fi module includes a complete TCP/IP stack and supports multiple network modes including Station, SoftAP, and Station+SoftAP, allowing flexible deployment in both client and access point scenarios. It also provides hardware acceleration for cryptographic functions such as WPA/WPA2 encryption, enhancing security without burdening the host microcontroller. The ATWILC1000 supports standard protocols like DHCP, DNS, HTTP, and TLS, simplifying integration into existing networking infrastructures. Designed for seamless compatibility with Microchip’s PIC32 microcontrollers and other 32-bit MCUs, the ATWILC1000 connects via a high-speed SPI interface, enabling fast data transfer and reduced latency. Its compact form factor and minimal external component requirements reduce board space and overall system cost, ideal for space-constrained designs. Additionally, the chip includes a robust antenna diversity feature to improve signal reliability in challenging RF environments. The ATWILC1000 is optimized for low-power operation, with sleep modes consuming less than 1 μA, which is critical for battery-powered devices such as wearables, remote sensors, and metering equipment. It supports advanced power-saving features like dynamic voltage scaling and automatic power-down during idle periods. Firmware updates are supported over-the-air (OTA), ensuring long-term maintainability and security patch deployment without physical intervention. Applications span from consumer electronics—such as smart thermostats, lighting controls, and home automation hubs—to industrial use cases like asset tracking, machine-to-machine communication, and remote monitoring systems. Its combination of performance, low power, and ease of integration makes it a preferred choice for developers seeking reliable wireless connectivity in resource-constrained environments.
