STM32WB35CCU6A

Product Overview

STM32WB35CCU6A is an ultra-low-power wireless microcontroller / RF transceiver SoC from STMicroelectronics. It integrates application processing, radio communication and STM32 peripheral resources in one device. It is commonly selected for smart-home nodes, connected lighting, wireless sensors, industrial IoT and battery-powered embedded products.

For design-in, continuation sourcing or repair work, engineers should review RF matching, antenna layout, interface timing, supply filtering and firmware compatibility. The selected orderable code should also be checked for package footprint, firmware or stack support, RF band, regulatory requirements and lifecycle status before approval.
