2. Overview
   The BK7239N is a highly integrated 1×1 tri-band 2.4/5/6 GHz Wi-Fi 6/6E (802.11a/b/g/n/ax), Bluetooth Low Energy (LE) 5.4, and IEEE 802.15.4 multi-protocol connectivity solution designed for applications that require high security and abundant resources. The integration of a 32-bit Armv8-M STAR-MC1 MCU and a comprehensive set of peripherals makes the BK7239N ideal for advanced Internet of Things (IoT) applications.
   The BK7239N provides state-of-the-art security based on a powerful security architecture. The BK7239N integrates a IoT Platform Security Suite (IPSS) for cryptograph and system security control. The IPSS embeds all-round and robust security features to set up a top-secret execution environment for IoT devices.
   Using advanced design techniques and ultra-low power process technology, the BK7239N delivers high integration, efficient security, and minimal power consumption for a wide range of advanced IoT applications.
   Figure 2-1 shows the general block diagram of BK7239N.
