New Dialog SoC Said to Enable 5-Year Battery Life for Always-on Wi-Fi Connectivity in Webcams

Dialog Semiconductor is shipping an ultra-low-power Wi-Fi SoC that can enable up to five-year battery operation from continuously connected devices, it announced Monday. The DA16200 was engineered for devices including connected door locks, thermostats and security video cameras that require “always on” Wi-Fi connectivity, it said. Minimum battery operating time is given as a year. The “highly integrated” DA16200 runs the full Wi-Fi system, security and networking protocol stack, eliminating the need for an external network processor, CPU or microcontroller, it said. One monolithic silicon die holds an 802.11b/g/n radio, baseband processor, MAC, on-chip memory, dedicated encryption engine and an ARM Cortex-M4F host networking applications processor. The company also announced the DA16600 module, which combines Wi-Fi from the DA16200 and Bluetooth Low Energy capabilities from its SmartBond TINY DA14531 SoC. The combo Wi-Fi and BLE module is said to eliminate issues caused by the coexistence of two radios at 2.4 GHZ in the same design.
