Equivalent & Alternatives
The following parts are listed as comparable options for similar Bluetooth Low Energy + NFC wireless MCU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| QN9090HN | No integrated NFC tag; identical Flash/SRAM, BLE radio, and peripherals otherwise | Suitable for BLE-only designs where NFC provisioning is handled externally or omitted | Select QN9090HN when NFC functionality is unnecessary and BOM cost reduction is prioritized over dual-interface flexibility |
| DA1469x series (Dialog/Infineon) | ARM Cortex-M33 core, 2 MB Flash, no integrated NFC; supports BLE 5.2 and Thread | Better suited for complex mesh networks or multi-protocol gateways requiring larger code space and higher throughput | Choose DA1469x when BLE 5.2 features, Thread compatibility, or >1 MB Flash are required - but expect added NFC component cost and layout complexity |
Compared with QN9090THN/001Z, QN9090HN removes NFC capability while retaining identical BLE performance and memory, whereas DA1469x offers newer BLE/Thread support and larger Flash but requires external NFC circuitry and increases system-level design effort.

FAQ
What is the primary function of the LA and LB pins on the QN9090THN/001Z?
The LA and LB pins on the QN9090THN/001Z provide the differential interface to an external NFC loop antenna, enabling the integrated NTAG I2C (NFC Forum Type 2) functionality. These pins connect directly to the antenna without requiring external matching components, allowing the QN9090THN/001Z to operate as a contactless tag for provisioning, configuration, or secure authentication.
Does the QN9090THN/001Z support Over-The-Air (OTA) firmware updates?
Yes, the QN9090THN/001Z supports OTA firmware updates via its 640 KB embedded Flash memory. The device includes dedicated bootloader support and secure update mechanisms leveraging its hardware AES-256 and SHA-256 accelerators, ensuring authenticated and encrypted firmware delivery over BLE connections without external memory.
How does the QN9090THN/001Z achieve 350 nA deep power-down current?
The QN9090THN/001Z achieves 350 nA deep power-down current by disabling all clocks except the 32.768 kHz oscillator, powering down the CPU, Flash, SRAM, and most peripherals while retaining wake-up capability on selected GPIOs. This state is managed by the Standby Power Controller and is validated across the −40 °C to +125 °C junction temperature range.
Can the QN9090THN/001Z operate with a single 3.0 V coin cell battery?
Yes, the QN9090THN/001Z operates from 1.9 V to 3.6 V, making it compatible with standard 3.0 V CR2032 coin cells. Its ultra-low active and deep power-down currents-combined with the integrated DC/DC converter (LX/FB pins)-enable multi-year battery life in duty-cycled sensing applications such as occupancy detectors or wellness trackers.
What distinguishes the QN9090THN/001Z from the QN9090HN variant?
The QN9090THN/001Z includes an integrated NTAG I2C NFC tag with dedicated LA/LB antenna pins, while the QN9090HN lacks NFC functionality entirely. Both share identical 640 KB Flash, 152 KB SRAM, BLE 5.0 radio performance, and HVQFN40 packaging-but only QN9090THN/001Z supports NFC-based provisioning, secure pairing, and tap-to-configure use cases.
