FAQ
What is the primary function of the QN9090THN/001K in a BLE system?
The QN9090THN/001K serves as a fully integrated Bluetooth Low Energy 5.0 wireless microcontroller, combining an Arm Cortex-M4 CPU, BLE 5.0 radio, NFC tag, analog/digital peripherals, and security accelerators in a single HVQFN40 package. It executes both the BLE protocol stack and application firmware, eliminating the need for external processors or companion radios. Its design enables self-contained, coin-cell-powered devices like wearables and sensors.
Does the QN9090THN/001K support Over-The-Air (OTA) firmware updates?
Yes, the QN9090THN/001K supports Over-The-Air firmware updates via its 640 KB embedded Flash memory. The Flash is partitioned to allow dual-bank operation, enabling safe background downloading and atomic switching between firmware versions without interrupting BLE connectivity. This capability is essential for long-lifecycle IoT deployments where field updates are required.
How does the integrated NTAG in the QN9090THN/001K differ from standalone NFC controllers?
The QN9090THN/001K integrates an NFC Forum Type 2-compliant NTAG I2C interface directly into the MCU die, sharing power domains and clocks with the BLE subsystem. Unlike standalone NFC controllers, it requires no external NFC controller IC, level shifters, or antenna matching networks-reducing BOM count and PCB area. LA/LB pins connect directly to a simple loop antenna, enabling tap-to-pair provisioning and secure credential loading.
What is the significance of the 350 nA deep power-down current in the QN9090THN/001K?
The 350 nA deep power-down current in the QN9090THN/001K enables multi-year battery life in intermittently active applications such as wireless occupancy sensors or environmental monitors. In this mode, only IO wake-up sources remain active; the CPU, radio, and most peripherals are powered down. Combined with 32 kHz wakeup timers capable of >1 year operation, this spec makes QN9090THN/001K ideal for maintenance-free edge sensing.
Can the QN9090THN/001K operate with a single coin-cell battery?
Yes, the QN9090THN/001K is explicitly designed for coin-cell operation, supporting 1.9 V to 3.6 V supply voltage. Its ultra-low 350 nA deep power-down current, 4.3 mA BLE receive current, and integrated DC-DC converter (with LX, FB, VBAT pins) maximize energy efficiency. Real-world implementations achieve 18–24 months runtime on a CR2032 battery in typical BLE sensor applications with periodic advertising and short connection intervals.
