1 General Description
1.1 Overview
The BK3432 chip is a highly integrated Bluetooth 4.2 dual mode with 2
Mbps data rate option. It integrates a high-performance RF transceiver,
baseband, ARM9E core, rich feature peripheral units, programmable
protocol and profile to support BLE application. The Flash program
memory makes it suitable for customized applications.
The BK3432 is designed with advanced technology process and integrated
with switch DCDC regulator, that it has 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.
