Top 10 IoT Chips to Watch in 2025: Powering the Future of Connected Devices
Every IoT product lives or dies by its chip. The wrong choice means your device drains batteries in a week, misses the connectivity standard that just became mainstream, or ships without the security features enterprise buyers now require. In 2025, the IoT chip market is more competitive — and more interesting — than ever. The Short Version Four requirements define what a serious IoT chip needs in 2025: energy efficiency, robust security, support for Matter and next-gen protocols, and on-device AI capability. The chips that nail all four are the ones shaping the next generation of connected products. Here's the list: Qualcomm QCA4020 — tri-mode SoC (BLE + Wi-Fi + 802.15.4) built for multi-protocol smart home ecosystems and Matter compatibility Nordic nRF5340 — dual-core Bluetooth 5.3 powerhouse with LE Audio and direction finding; the go-to for wearables and health monitors Espressif ESP32-C6 — the developer favorite evolves: Wi-Fi 6, BT 5 LE, native Matter support, and l...
