The chip is fit for low power application, such as wearable devices, internet of things, remote MH8100 BLE SOC controller, data communication, POS, Homelit, Beacon.
The BOM cost is lowest, because the on-chip balun does not require any RF matching, thecrystal load capacitoris internal programmable, and the 32kHz oscillator is integrated. The high efficiency on-chip DC-DC converter allows for a ultralow power consumption.
