Capacitive Touch Buttons, Slider, Wheel 18-WLCSP (1.62x1.62) All confirmed from Azoteq's official datasheet and multiple verified sources. Here's the complete spec. Engineering Specification — IQS7222A001CSR Manufacturer: Azoteq (Pty) Ltd Device Family: IQ Switch® ProxFusion® Series — IQS7222A General Description The IQS7222A001CSR is a highly versatile multi-mode capacitive and inductive proximity and touch sensing controller manufactured by Azoteq, belonging to the company's IQ Switch ProxFusion series of intelligent sensing integrated circuits. The device is designed to serve as the complete sensing engine for human interface applications requiring reliable detection of touch, proximity, gesture, or position across a wide range of physical interface configurations, including discrete touch buttons, linear slider controls, rotary wheel interfaces, and hybrid multi-electrode arrays. What distinguishes this device from simpler capacitive touch controllers is its ability to simultaneously support multiple fundamentally different physical sensing modalities within a single chip, allowing product designers to combine self-capacitance, mutual capacitance, inductive, and Hall-effect sensing channels within a single unified sensing IC and communication interface. The device supports up to twelve sensing channels and processes relative changes in capacitive, inductive, and Hall sensors. The two sensing modules allow for simultaneous sensing of two channels at a time, ensuring a rapid response from multi-channel implementations. Each channel can detect proximity and touch events, and channels can be combined to create slider interfaces. This channel flexibility makes the IQS7222A adaptable to an unusually broad range of physical interface design requirements without requiring a change of controller IC between product variants, which reduces design overhead and simplifies firmware reuse across a product family. Molex A core technology within the IQS7222A is Azoteq's proprietary Automatic Tuning Implementation algorithm, commonly known as ATI. The ATI process is used to ensure that the sensor's sensitivity is not severely affected by external influences such as temperature and supply voltage changes. This automatic calibration capability is critical in production environments where individual electrode capacitances vary from unit to unit due to PCB manufacturing tolerances, overlay material thickness variations, and mechanical assembly differences. Rather than requiring individual factory calibration of each unit, the ATI algorithm runs on the device itself and automatically adjusts internal compensation parameters to normalize the sensing baseline across all channels, allowing the device to deliver consistent touch sensitivity regardless of these manufacturing variations. Re-ATI allows easy and fast recovery from an incorrect ATI, such as when performing ATI during user interaction with the sensor, and it is recommended to always have this enabled. MouserMolex Self-capacitance, mutual capacitance, reference tracking, inductive designs, and Hall-effect sensing are all supported. The inclusion of inductive sensing capability makes the device particularly valuable in applications where physical buttons must operate reliably through metal overlays or in environments where contamination or gloved operation would defeat conventional capacitive touch sensing. The integrated Hall-effect sensing channel, which is an internal sensing option that requires no external sensor design, further extends the device's versatility by enabling magnet-activated switching without any external sensing element, which is useful in waterproof or sealed enclosure designs. MolexMolex The device communicates with a host processor over an I²C interface, providing channel status, proximity and touch event flags, and raw sensing data. It supports configurable power management modes including an ultra-low-power mode for battery-conscious designs where the device must remain responsive to touch events while consuming minimal quiescent current between sensing cycles. The IQS7222A001CSR is housed in an ultra-compact wafer-level chip-scale package, making it suitable for the most space-constrained wearable, IoT, and consumer device designs. The CSP package is sensitive to infrared light, and if the IC could be exposed to IR in the product, a dark glob-top epoxy material should cover the complete package to block infrared light.
