FAQ
What is the maximum transmit power and corresponding current draw for QN9090HN/001Y?
QN9090HN/001Y supports configurable transmit power up to +11 dBm, drawing 20.3 mA at +10 dBm, 9.4 mA at +3 dBm, and 7.4 mA at 0 dBm. These values are measured under typical 3.0 V supply conditions and reflect actual RF output stage efficiency-enabling range optimization without exceeding coin-cell peak current limits.
Does QN9090HN/001Y include NFC functionality?
No, QN9090HN/001Y does not include NFC. It is the non-NFC variant of the QN9090 family. The QN9090THN part adds an integrated NTAG I²C NFC Forum Type 2 tag with dedicated LA/LB antenna pins. QN9090HN/001Y uses those pins as no-connect (n.c.) to maintain pin compatibility while reducing cost and RF layout overhead.
What crystal frequencies are required for full QN9090HN/001Y operation?
QN9090HN/001Y requires two crystals: a 32 MHz fundamental-mode crystal on XTAL_P/XTAL_N for system clock and radio timing, and a 32.768 kHz tuning-fork crystal on XTAL_32K_P/XTAL_32K_N for RTC and BLE connection interval timing. Both crystals must meet specified load capacitance and stability specs to ensure BLE 5.0 compliance.
How many simultaneous Bluetooth Low Energy connections does QN9090HN/001Y support?
QN9090HN/001Y supports up to eight simultaneous Bluetooth Low Energy connections-four as central and four as peripheral roles. This capability is implemented in hardware-accelerated link-layer firmware and enables hub-and-spoke topologies such as smart home gateways aggregating multiple sensors without host CPU intervention.
What debug interface does QN9090HN/001Y use, and which pins are required?
QN9090HN/001Y uses Serial Wire Debug (SWD) with SWCLK (PIO12) and SWDIO (PIO13) pins. TRST must be hardwired to GND per datasheet; no JTAG TDI/TDO/TMS pins are exposed. SWO (Serial Wire Output) is available on PIO14/ADC0 for real-time trace streaming during development.
