        The BK3432 chip is a highly integrated Bluetooth 4.2 dual-mode with 2Mbps of the data transfer rate for the SoC.

BK3432 not only integrates high-performance RF transceivers, baseband, and ARM9E cores but also has rich characteristic peripheral units to program protocols and profiles and their support for BLE applications.

       First of all, the BK3432 uses an advanced process design, integrated with the switch DCDC regulator, and also has ultra-low power consumption and ultra-low leakage power. Secondly, the embedded high-order interference suppression filter and the fast automatic gain control logic make it work well in the high interference environment.
