Overview
QN9090HN/001K from NXP Semiconductors is an Arm® Cortex®-M4 based Bluetooth Low Energy 5.0 wireless microcontroller with 640 KB Flash, 152 KB RAM, and integrated 2.4 GHz BLE transceiver supporting eight simultaneous connections. It delivers ultra-low power operation (350 nA deep power-down current), 2 Mbps data rate, -97 dBm receiver sensitivity, and on-chip DMIC subsystem with voice activity detection for battery-powered wearables and sensors.
For engineers reviewing the QN9090HN/001K datasheet, QN9090HN/001K pinout, QN9090HN/001K application, or QN9090HN/001K equivalent, this page provides verified technical context, validated pin functions, real-world use cases, and confirmed alternative parts for BLE 5.0 embedded designs requiring coin-cell operation, secure OTA updates, and dual-channel PDM microphone support.
Technical Context
The QN9090HN/001K integrates a 48 MHz Arm Cortex-M4 CPU with Memory Protection Unit (MPU), Serial Wire Debug (SWD), and hardware accelerators for AES-128/256, SHA-1/SHA-256, and random number generation. Its BLE 5.0 radio includes antenna diversity control, integrated RF balun, and configurable transmit power up to +11 dBm across 46 dB range.
Power management supports five low-power states - Sleep, Deep-sleep, Power Down, Deep Power-down (350 nA), and dedicated BLE link-layer timer running on 32 kHz XTAL - enabling multi-year operation on coin cells. The device uses a 32 MHz crystal oscillator with internal capacitors and includes a 32.768 kHz XTAL interface for RTC timing.
