IQS7222D001QFR

Overview

The IQS7222D001QFR is a sensor interface IC from Azoteq's ProxFusion series, designed for capacitive sensing applications. It supports 14 channels of mutual capacitance and 8 channels of self-capacitance sensing. The device communicates via an I2C interface and includes configurable general-purpose input/output (GPIO) pins. It operates within a supply voltage range of 1.71V to 3.5V and functions in temperatures from -40°C to +85°C. Packaged in a 20-UFQFN with exposed pad, it is supplied in reel or cut tape formats.

Feature Summary

Supports simultaneous detection using both mutual and self-capacitive sensing modes for versatile touch interaction.
Integrates configurable GPIOs to allow flexible system integration and control logic expansion.
Utilizes I2C communication protocol for efficient data transfer and simplified host microcontroller interfacing.

Applications

Capacitive touch button interfaces
Slider and rotary encoder implementations
Proximity detection systems

Procurement Notes

Verify the specific suffix QFR indicates the reel packaging configuration when ordering. Confirm RoHS compliance status through the manufacturer's official documentation prior to procurement. Ensure the supplier is authorized to provide genuine Azoteq components to guarantee product authenticity and reliability.

Selection Notes

Select this model when the design requires 14 mutual and 8 self-capacitive channels. Compare against IQS7222B variants if different channel counts are needed. Verify that the 20-QFN package dimensions fit the PCB layout constraints. Check compatibility with the host I2C bus speed requirements.

Part Context

This component belongs to the IQS7222 family, which offers various channel configurations for capacitive sensing. The D variant specifically provides 14 mutual and 8 self-cap channels. Other family members like IQS7222A, B, and C offer different channel mixes or additional features such as inductive sensing support.

Replacement Considerations

Check for direct pin-to-pin replacements within the IQS7222 series. IQS7222B variants may serve as alternatives if channel counts align. Verify software compatibility and GUI configuration files before substituting any other part number.
