- Commodity name: BK3633 Bluetooth 5.2 dual-mode and proprietary 2.4GHz on-chip wireless system
Overview
The BK3633 chip is a highly integrated on-chip wireless system that supports Bluetooth 5.2 dual-mode and proprietary 2.4GHz protocol.
It integrates high-performance RF transceivers, baseband, low-power processors, rich functional peripheral units, programmable protocols, and configuration files to support a wide range of applications. Flash program storage makes it suitable for customized applications.
BK3633 adopts advanced technology design and integrates switch DCDC voltage regulator, which has the characteristics of ultra-low power consumption and ultra-low leakage.
Embedded high-order interference suppression filter and fast automatic gain control logic, it can also work normally in high interference environments.
