- Commodity name: BK3635 Single chip Bluetooth 5.2 (BR/LE) and 2.4GHz proprietary protocol System on Chip (SoC)
Overview
BK3635 is a highly integrated single-chip Bluetooth 5.2 (BR/LE) and 2.4GHz proprietary protocol system on chip (SoC). It integrates a high-performance 2.4GHz RF transceiver, a feature rich baseband processor, a memory controller, multiple analog and digital peripherals, as well as Bluetooth and 2.4GHz proprietary protocol stacks.
BK3635 adopts advanced design technology and ultra-low power consumption process technology, providing high integration and minimal power consumption for a wide range of IoT (Internet of Things) and HID (Human Interface Device) applications, such as voice remote controllers, wearable devices, mouse devices, keyboards, and USB dongles.
