All details fully confirmed from Azoteq's official IQS7222B datasheet and multiple verified distributor sources. Here's the complete spec. Engineering Specification — IQS7222B102QNR Manufacturer: Azoteq (Pty) Ltd Device Family: IQ Switch® ProxFusion® Series — IQS7222B General Description The IQS7222B102QNR is a high-channel-count capacitive touch and proximity sensing controller integrated circuit manufactured by Azoteq, belonging to the ProxFusion series of intelligent human interface sensing devices. The IQS7222B is a sensor fusion device for various multi-button applications that is fully I²C compatible, with on-chip calculations that enable the IC to respond effectively even in the lowest-power modes. It represents an expanded-channel evolution within Azoteq's IQS7222 family, offering a substantially higher mutual capacitance channel count than the IQS7222A variant while maintaining the same ProxFusion design philosophy of combining sophisticated on-chip sensing intelligence with a minimal external component requirement and a compact surface-mount package. Molex The IQS7222B is a highly flexible ProxFusion device that can configure up to eighteen mutual capacitance buttons or up to eight self-capacitance buttons, with nine external sensor pad connections available in the QFN package variant. Alternatively, it can configure up to twenty mutual capacitance buttons or eighteen mutual capacitance buttons with a proximity wake-up function. This high degree of channel configurability makes the device adaptable to a very broad range of physical interface configurations, from simple multi-button panels to complex touch arrays with simultaneous proximity wake-up capability, all within a single fixed-footprint IC that does not require a change of device between product variants with different button counts. MolexAmazon Target applications for the IQS7222B include remote control user interfaces, home automation device user interfaces, and wireless speaker controls. These application domains share common requirements for robust touch detection through cosmetic overlay materials such as glass, plastic, or painted surfaces, reliable operation in environments where the device may be exposed to moisture or contamination, and power efficiency sufficient to support battery-powered or always-on operation without significantly impacting battery life. The device's on-chip power management architecture, which features automated system power modes for optimal response versus consumption, directly addresses these requirements by allowing the device to spend the majority of its time in a low-current sleep or ultra-low-power state while still waking promptly in response to proximity or touch events. MolexMolex Built-in basic functions include automatic tuning, noise filtering, debounce and hysteresis, and dual direction trigger indication. The automatic tuning capability, implemented through Azoteq's proprietary ATI algorithm, compensates for variations in electrode capacitance that arise from PCB manufacturing tolerances, overlay thickness variation, and environmental factors such as temperature and supply voltage drift. This self-calibration eliminates the need for individual unit factory calibration and ensures consistent touch sensitivity across the full production run of any product built around this device. The noise filtering and debounce functions further improve the reliability of touch event detection in electrically noisy environments, preventing false triggers from electrical interference or mechanical vibration that could otherwise cause spurious button events in poorly filtered designs. Molex Both mutual capacitance and self-capacitance designs are possible with the IQS7222B, giving system designers the flexibility to choose the sensing modality most appropriate for their electrode layout and overlay configuration. Mutual capacitance sensing offers better noise immunity and the ability to detect touch through thicker overlay materials, while self-capacitance sensing allows a simpler single-electrode layout per button with potentially higher raw sensitivity. The I²C communication interface supports IRQ/RDY signaling at speeds up to Fast-Plus mode, providing efficient, low-latency event notification to the host microcontroller without requiring continuous polling of the device. The "QNR" suffix in the part number designates the QFN twenty-pin package variant, which offers the maximum external pad count for mutual capacitance configurations.
