QN908x Ultra low power Bluetooth 5 system-on-chip solution Rev. 1.3 6 January 2021 Product data sheet 1. Introduction QN908x is an ultra low power Bluetooth Low Energy wireless MCU with on-chip memory, USB 2.0 full-speed compliant device interface, and 16-bit ADC for Bluetooth Smart applications. QN9080 integrates a 32-bit ARM Cortex-M4F core with Bluetooth Low Energy (v5.0) compliant radio, link controller, host stack and GATT profiles. The 32-bit ARM Cortex-M4F MCU and on-chip memory provides additional signal processing and scope to run applications for a true single-chip Bluetooth Low Energy (v5.0) solution. The QN908x uses a multi-layer AHB matrix to connect the ARM Cortex-M4 buses and other bus masters to peripherals in a flexible manner. It optimizes performance by allowing peripherals that are on different slave ports of the matrix to be accessed simultaneously by different bus masters. 2. General description The QN908x is a single chip, 1.6 mW peak power, high performance Bluetooth Low Energy SoC platform. It facilitates the development of end products such as wearables, health, and sport and fitness trackers. The end products also include retail beacons, connected smart home appliances, smart remote controls, HID devices, asset trackers, and home automation. QN9080 provides single-chip solution for Bluetooth Smart applications by integrating a Bluetooth Low Energy (v5.0) compliant radio, link controller, host stack and GATT profiles. The integrated 32-bit ARM Cortex-M4F MCU with on-chip flash memory and a mix of analogue and digital peripherals provides the most efficient data fusion engine. The feature makes it a superior solution for applications requiring significant sensor fusion computation. Additional system features include a fully integrated DC-to-DC converter, LDO, low-power sleep timer, battery monitor, high resolution ADC, and GPIO. These features reduce overall system cost and size. The QN908x operates with a power supply range of 1.62 V to 3.6 V. The best in-class active current, with ultra-low power sleep modes, give excellent battery life allowing operation from a coin cell battery. NXP reserves the right to change the production detail specifications as may be required to permit improvements in the design of its products.
