QN902X
Ultra Low Power BLE System-on-Chip Solution
Rev. 1.1 — 10 February 2015
Product data sheet
1. Introduction
QN902x is an ultra-low power wireless System-on-Chip (SoC) for Bluetooth Smart
applications, supporting both master and slave modes. It 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 v4.0 Low Energy 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 provide additional signal processing and
room to run applications for a true single-chip Bluetooth Smart solution. In addition,
QN902x can also be utilized as a network processor by connecting to an application
processor via UART or SPI to add Bluetooth Smart feature to any products.
QN902x comes with complete analog peripherals and digital interfaces to enable easy
connection to any analog or digital peripherals or sensors, and external application
processor in network processor mode.
2. General description
QN902x is an ultra-low power, high performance and highly integrated Bluetooth v4.0
Low Energy (BLE) solution for Bluetooth Smart applications such as sports/fitness,
human interface devices, and app-enabled smart accessories. It is especially designed
for wearable electronics and can run on small capacity battery such as a coin cell battery.
QN902x integrates a BLE radio, controller, protocol stack and profile software on a single
chip, providing a flexible and easy to use BLE SoC solution. It also includes a high
performance MCU and 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/DC and LDO, low power sleep
timer, battery monitor, general purpose ADC, and GPIOs, to further reduce overall
system cost and size. QN902x operates with a power supply range of
2.4 V to 3.6 V and has very low power consumption in all modes, enabling long lifetimes
in battery-operated systems while maintaining excellent RF performance.
