Product details
Overview
QN9090THN/001Y from NXP Semiconductors is an ultra-low-power, Arm® Cortex®-M4 based Bluetooth Low Energy 5.0 wireless microcontroller with 640 KB Flash, 152 KB SRAM, integrated NFC tag (NTAG I2C), and a 2.4 GHz BLE 5.0 transceiver supporting +11 dBm transmit power and −97 dBm receiver sensitivity. It enables coin-cell-powered wearable health monitors and secure smart home sensors.
For engineers reviewing the QN9090THN/001Y datasheet, QN9090THN/001Y pinout, QN9090THN/001Y application, or QN9090THN/001Y equivalent, this page delivers verified specifications, HVQFN40 pin mapping, BLE 5.0 + NFC system integration details, low-power mode current values (350 nA deep power-down), and validated alternative parts for design continuity.
Technical Context
The QN9090THN/001Y integrates an Arm Cortex-M4 CPU running at up to 48 MHz with memory protection unit (MPU), NVIC, and Serial Wire Debug, alongside a fully compliant BLE 5.0 radio featuring antenna diversity control, integrated RF balun, and configurable TX power (−10 to +11 dBm). Its dual-clock architecture uses 32 MHz XTAL for radio timing and 32.768 kHz XTAL for RTC and low-power timers.
On-chip peripherals include a 12-bit 8-channel ADC (190 ksamples/s), dual PDM microphone interface with hardware voice activity detection, two I²C, two SPI, two USART, 10 PWM channels, ISO7816 smart card interface, and dedicated security accelerators for AES-128/192/256 and SHA-1/SHA-256 - all operating within 1.9–3.6 V supply range and −40 °C to +125 °C junction temperature.

Yes, the QN9090THN/001Y includes a dedicated AES-128/192/256 encryption engine, SHA-1/SHA-256 hash accelerator, and eFuse storage for 128-bit random keys - enabling secure boot and authenticated Over-The-Air (OTA) firmware updates. These features are integral to the QN9090THN/001Y silicon and require no external components to implement cryptographic integrity checks.
How many simultaneous Bluetooth Low Energy connections does the QN9090THN/001Y support?
The QN9090THN/001Y supports up to eight simultaneous BLE connections, managed by its on-chip link layer and host stack. This capability is confirmed in the official NXP product data sheet Rev. 1.2 and enables hub-like behavior in sensor networks or multi-peripheral accessories - all without external co-processors or additional memory.
What is the deep power-down current consumption of the QN9090THN/001Y, and how is wake-up implemented?
The QN9090THN/001Y achieves 350 nA deep power-down current with wake-up enabled on selected GPIOs. Wake-up sources also include low-power timers, I²C, USART, and SPI peripherals operating in limited function mode. This specification is measured per NXP's characterization and allows multi-year battery life in intermittently active applications like wireless occupancy sensors.
Is the NFC functionality in the QN9090THN/001Y compatible with standard NFC readers?
Yes, the QN9090THN/001Y integrates an NFC Forum Type 2 tag (NTAG I2C) compliant with ISO/IEC 14443-A and NFC Data Exchange Format (NDEF).
