Overview
The IQS320100CSR is a ProxFusion® Series integrated circuit designed for high-performance proximity sensing in environments with high capacitive loads, such as SAR applications. It features dual-channel self-capacitance sensing with an I²C interface supporting up to 1 MHz. The device operates on a supply voltage of 1.71 V to 3.5 V and includes built-in automatic tuning, noise filtering, and movement detection. Key user interfaces include Reference Tracking, Movement, and SNR Boost. It supports standalone output mode and event/streaming communication modes.
Feature Summary
- Dual-channel self-capacitance sensor optimized for high capacitive load environments
- Built-in Automatic Tuning Implementation (ATI) for optimal performance without external component modification
- Integrated Signal Processing Options including Movement UI, Reference UI, and SNR Boost via oversampling
- Flexible I²C communication interface with selectable address and standalone output capability
Applications
- SAR Safety Sensor
- Keyboard back-lighting control
- Wireless charger wake-up detection
Procurement Notes
Verify the specific package variant required, as the IQS320 series is available in WLCSP11, DFN12, and QFN20 packages. Confirm that the ordering suffix corresponds to the desired packaging format and pin configuration. Ensure compatibility with the host system's I²C voltage levels and address settings before finalizing procurement.
Selection Notes
Select this component for applications requiring robust proximity detection under high capacitance conditions. Consider the SNR Boost feature for critical triggers and the Reference UI for stability. Evaluate the need for standalone mode versus I²C master control based on system architecture requirements.
Part Context
The IQS320100CSR belongs to Azoteq’s ProxFusion® family, which specializes in self-capacitive and inductive sensing technologies. This series is engineered to handle complex environmental interference and high load capacitances, distinguishing it from standard touch controllers by its advanced signal processing capabilities.
Replacement Considerations
Check datasheet specifications for compatible substitutes within the IQS320 series or other Azoteq ProxFusion devices. Verify pinout compatibility and software register map differences if replacing with variants like IQS320A or different package options.
