Rev. 2.7 — 21 November 2018
Product data sheet
1. Introduction
QN902x is an ultra low power, wireless System-on-Chip (SoC) for Bluetooth Smart
applications. It supports both master and slave modes. QN902x integrates a high
performance 2.4 GHz RF transceiver with a 32-bit ARM Cortex-M0 MCU, flash memory,
and analog and digital peripherals.
By integrating a Bluetooth LE v4.2 compliant radio, link controller and host stack, QN902x
provides a single-chip solution for Bluetooth Smart applications. The 32-bit ARM
Cortex-M0 MCU and on-chip memory provides additional signal processing and room to
run applications for a true single-chip Bluetooth Smart solution. In addition, QN902x can
be used as a network processor by connecting to an application processor via UART or
SPI. It helps to add Bluetooth Smart feature to any product.
QN902x has built-in analog and digital interfaces. It enables easy connection to any
analog or digital peripheral, sensor, and external application processor in network
processor mode.
2. General description
QN902x is an ultra low power, high performance and highly integrated Bluetooth LE
solution. It is used in Bluetooth Smart applications such as sports and fitness, human
interface devices, and app-enabled smart accessories. It is specially designed for
wearable electronics and can run on a small capacity battery such as a coin cell battery.
QN902x integrates a Bluetooth LE radio, controller, protocol stack and profile software on
a single chip, providing a flexible and easy to use Bluetooth LE SoC solution. It also has a
high performance MCU and an on-chip memory that can support users to develop a
single-chip wireless MCU solution. Users can also utilize QN902x as a network processor
by connecting to an application processor for more advanced applications.
Additional system features include fully integrated DC-to-DC converter and LDO,
low-power sleep timer, battery monitor, general-purpose ADC, and GPIOs. These features
reduce overall system cost and size. QN902x has very low power consumption in all
modes. It enables long life in battery-operated systems while maintaining excellent RF
performance. QN9020/1 operates with a power supply range of 2.4 V to 3.6 V. The
QN9022 operates with a power supply range of 1.8 V to 3.6 V.
