Introduction

The QN908x is an ultra-low-power Bluetooth Low Energy wireless MCU integrating on-chip memory, a USB 2.0 full-speed compatible device interface, and a 16-bit ADC, making it suitable for Bluetooth Smart applications. The QN9080 integrates a 32-bit ARM Cortex-M4F core with support for Bluetooth Low Energy (v5.0)-compatible radio, link controller, Host stack, and multiple GATT profiles. The 32-bit ARM Cortex-M4F MCU and on-chip memory provide additional signal processing capability and range, enabling applications to run as a true single-chip Bluetooth Low Energy (v5.0) solution. The QN908x uses a multi-layer AHB matrix to flexibly connect the ARM Cortex-M4 bus and other bus masters to peripherals, optimizing overall performance. The QN908x is a high-performance Bluetooth Low Energy SoC single-chip platform with 10 mW peak power, simplifying the development of end products such as wearables, healthcare products, and sports and fitness trackers. Such end products also include retail beacons, connected smart appliances, smart remote controls, HID devices, asset trackers, and home automation devices. The QN9080 integrates a Bluetooth Low Energy (v5.0)-compatible radio, link controller, Host stack, and multiple GATT profiles, providing a single-chip solution for Bluetooth Smart applications. The integrated 32-bit ARM Cortex-M4F MCU features on-chip flash memory along with a variety of analog and digital peripherals, delivering a more efficient data fusion engine suited for applications requiring intensive sensor fusion computation. Additional system features include a fully integrated DC-DC converter, LDO, low-power sleep timer, battery monitor, high-resolution ADC, and GPIO, reducing overall system cost and form factor. The QN908x operates over a supply voltage range of 1.62 V to 3.6 V, with very low operating current and an ultra-low-power sleep mode that extends battery life, enabling long runtime from a single coin cell battery.
