Product details
Overview
QN9022/DY from NXP Semiconductors is an ultra-low-power Bluetooth LE 4.2 System-on-Chip integrating a 32-bit ARM Cortex-M0 MCU, 2.4 GHz RF transceiver, 128 kB flash (external interface), 64 kB system memory, and analog/digital peripherals. It operates from 1.8 V to 3.6 V, delivers −93 dBm RX sensitivity (DC-DC mode), supports master/slave dual-mode operation, and targets coin-cell-powered wearable electronics.
For engineers reviewing the QN9022/DY datasheet, QN9022/DY pinout, QN9022/DY application, or QN9022/DY equivalent, this page delivers verified technical context on its BLE SoC architecture, HVQFN40 package integration, low-power sleep modes (2 µA deep sleep), UART/SPI/I²C interfaces, and role as either standalone wireless MCU or network processor - all critical for wearable, sensor, and medical BLE design validation.
Technical Context
QN9022/DY implements a fully integrated Bluetooth LE v4.2 stack with radio, link controller, and host software on-die, enabling direct BLE connectivity without external protocol handling. Its ARM Cortex-M0 core executes user applications while managing BLE timing via dual oscillators: 16/32 MHz HFXO for radio accuracy and 32.768 kHz LFXO for low-power RTC/sleep timer synchronization.
The device uses a configurable DC-to-DC converter to reduce active current by ~30%, achieving 8.8 mA TX @ 0 dBm and 9.25 mA RX. Its analog subsystem includes a 4-channel 10-bit ADC, two analog comparators, battery monitor, and AES-128 coprocessor - all accessible via GPIOs mapped to its 40-pin HVQFN40 footprint with dedicated RF ports (RFP/RFN) and crystal terminals (XTAL1/XTAL2).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| BLE Standard | Bluetooth LE v4.2 compliant radio + full protocol stack and profiles - enables certified out-of-box BLE connectivity without external host processing. |
| Supply Voltage | 1.8 V to 3.6 V - supports direct operation from single coin-cell batteries (e.g., CR2032) and eliminates need for external voltage regulation in space-constrained wearables. |
| RF Performance | −93 dBm RX sensitivity (DC-DC mode); +4 dBm to −20 dBm programmable TX power - ensures robust link budget up to 99 dB for reliable short-range sensor telemetry. |
| Power Modes | 2 µA deep sleep (RAM retained); 3 µA sleep (32 kHz RC on); 8.8 mA TX @ 0 dBm - extends battery life to months in intermittent-sensing applications like fitness trackers. |
| Memory | 64 kB system RAM; external flash interface (no on-chip flash) - allows flexible firmware storage and over-the-air updates using cost-optimized external SPI flash. |
| Peripherals | 4-channel 10-bit ADC; two analog comparators; two UARTs; two SPIs; I²C; AES-128 coprocessor; 22 GPIOs - enables direct sensor interfacing, secure data encryption, and multi-interface host communication. |
| Package | HVQFN40, 5 mm × 5 mm × 0.85 mm - compact thermal-enhanced quad flat no-lead package optimized for high-density PCB layouts in miniature wearables. |
Pinout & Package
HVQFN40 package (SOT1369-2), 5 mm × 5 mm body, 0.85 mm height, thermally enhanced with grounded back plate. Pin 1 marked by top-side dot; requires PCB ground connection to back plate for optimal RF performance and thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Core power supply | Primary digital supply input (1.8–3.6 V); decoupling required per layout guidelines to stabilize MCU and BLE baseband operation. |
| RFP / RFN (Pins 34 / 33) | Differential RF port | Direct connection points for 50 Ω antenna matching network; require controlled-impedance routing and minimal stub length for optimal 2.4 GHz radiation efficiency. |
| XTAL1 / XTAL2 (Pins 39 / 40) | HF crystal oscillator inputs | Interface to 16 MHz or 32 MHz fundamental-mode crystal; internal load capacitance reduces external BOM count and simplifies clock circuit design. |
| XTAL1_32K / XTAL2_32K (Pins 5 / 4) | LF crystal oscillator inputs | Connect to 32.768 kHz tuning-fork crystal for precise RTC and BLE advertising interval timing; essential for low-power periodic wake-up scheduling. |
| RSTN (Pin 31) | Active-low hardware reset | Asynchronous reset input; must be held low ≥100 ns to initiate cold boot; compatible with push-button or supervisor IC reset circuits. |
| P0_0–P0_7, P1_0–P1_7 | Wake-capable GPIOs | Only these 16 pins can exit sleep/deep sleep modes via interrupt - critical for designing responsive low-power sensor wakeup logic. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Bluetooth LE SoC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| nRF52833 DK | ARM Cortex-M4F core; 512 kB flash; integrated DC-DC; supports Bluetooth 5.1 and Thread - higher compute headroom but larger die size and 3.3 V min supply. | Better suited for complex mesh networking or audio streaming; less optimal for coin-cell wearables due to higher active current (4.9 mA RX). | Select nRF52833 DK when BLE 5.1 features (coded PHY, AoA/AoD) or concurrent multiprotocol operation are required. |
| DA14585-01FXQ2 | ARM Cortex-M0+ core; 64 kB RAM; 2 MB flash; 1.7–3.6 V supply; −95 dBm RX sensitivity - superior sensitivity but lacks integrated DC-DC and has larger HVQFN48 package. | Preferred for long-range industrial sensors where sensitivity outweighs size constraints; no built-in AES accelerator limits secure firmware update throughput. | Choose DA14585-01FXQ2 for applications demanding maximum link margin (>100 dB) and large local code storage without external flash. |

FAQ
What is the minimum supply voltage supported by QN9022/DY?
QN9022/DY operates from 1.8 V to 3.6 V, enabling direct use with common coin-cell batteries like CR2032 (nominal 3.0 V, discharge down to ~2.0 V) and alkaline cells. This 1.8 V lower limit distinguishes it from QN9020/1 (2.4 V min) and allows deeper battery utilization before system shutdown.
Does QN9022/DY include on-chip flash memory?
No, QN9022/DY does not integrate on-chip flash memory. Instead, it provides a dedicated external flash interface supporting SPI-connected flash devices. This architecture allows scalable firmware storage (e.g., 1–8 MB) and field-upgradable code without die size penalty - unlike QN9020/1 which embed 128 kB flash.
How many GPIOs are available on QN9022/DY, and which support wake-from-sleep?
QN9022/DY provides 22 general-purpose I/O pins. Only P0_0 through P0_7 and P1_0 through P1_7 (16 total) are capable of generating interrupts to wake the device from sleep or deep sleep modes - a hardware constraint critical for low-power sensor polling architecture.
What RF performance metrics define QN9022/DY's link reliability?
QN9022/DY achieves −93 dBm RX sensitivity in DC-DC mode and supports TX output from −20 dBm to +4 dBm, yielding a maximum link budget of 99 dB. Combined with fast RSSI and channel quality indication, this ensures robust connectivity in noisy 2.4 GHz environments typical of dense consumer electronics deployments.
Which communication interfaces does QN9022/DY support for connecting to external sensors or hosts?
QN9022/DY integrates two UARTs (supporting BLE Direct Test Mode), two SPIs (master/slave, 4-/3-wire), and one I²C-bus interface (master/slave, up to 400 kbit/s). These enable simultaneous connection to digital sensors (e.g., I²C accelerometer), host processors (UART), and external flash (SPI) - all without external level shifters or bus expanders.
