BK3633

Bluetooth 5.2 Dual Mode and Proprietary 2.4 GHz Wireless System on

Overview




The BK3633 chip is a highly integrated wireless system on chip, which supports Bluetooth 5.2 Dual Mode and proprietary 2.4 GHz protocols. It integrates a high-performance RF transceiver, baseband, low power processor, rich feature peripheral units, programmable protocol and profile to support a wide range of applications. The Flash program memory makes it suitable for customized applications.
Designed with advanced technology process and integrated with switch DCDC regulator, the BK3633 features ultra-low power consumption and ultra-low leakage power. The embedded high order interference suppression filter and fast automatic gain control logic make it work well in high interference environment.
