QN9090(T)/QN9030(T)
QN9090
Bluetooth Low Energy 5.0 wireless MCU
Rev. 1.2 — May 2021
Product data sheet
1. General description
The QN9090 and QN9090T (called QN9090 throughout this document) are ultra-low
power, high performance Arm® Cortex®-M4 based wireless microcontrollers supporting
Bluetooth Low Energy 5.0 to facilitate the development of Bluetooth Low Energy
applications.
The QN9090, supporting eight simultaneous connections, includes a 2.4 GHz Bluetooth
Low Energy 5 compliant transceiver and a comprehensive mix of analog and digital
peripherals. Ultra-low current consumption in both radio receive and transmit modes and
also in the power down modes allow use of coin cell batteries.
The product has 640 KB embedded Flash, 152 KB RAM memory. The embedded flash
can support Over The Air (OTA) code download to applications. The devices include
10-channel PWM, two timers, one RTC/alarm timer, a Windowed Watchdog Timer
(WWDT), two USARTs, two SPI interfaces, two I2C interfaces, a DMIC subsystem with
dual-channel PDM microphone interface with voice activity detector, one 12-bit ADC,
temperature sensor and comparator.
The QN9090T variant has an internal NFC tag with connections to the external NFC
antenna.
The QN9030 variant has the same functionality as the QN9090 except for reduced
memory sizes of 320 KB embedded Flash, 88 KB RAM. The QN9030T variant has the
functionality of the QN9030 with the addition of an embedded NFC tag.
The Arm Cortex-M4 is a 32-bit core that offers system enhancements such as low power
consumption, enhanced debug features, and a high level support of the block integration.
The Arm Cortex-M4 CPU, operates at up to 48 MHz.
