IQS323001DNR
Overview
The IQS323001DNR is a versatile capacitive and inductive sensing controller designed for high-performance touch and proximity applications. It features a 14 MHz CPU and three input channels capable of self-capacitive, mutual-capacitive, and inductive sensing, allowing for the detection of touch, gestures, and metal. With a wide supply voltage of 1.71V to 3.5V and specialized low-power modes, it is optimized for battery-operated devices requiring robust user interfaces.
Why Choose This Part
The device offers exceptional flexibility by supporting multiple sensing technologies (capacitive and inductive) on a single chip. Its sophisticated power management, including a 6.5uA standby current, extends battery life significantly. Integrated noise filtering and automatic tuning ensure reliable operation in electrically noisy environments or varying mechanical tolerances.
Applications
Key Specifications
Getting Started
To evaluate the IQS323, engineers should utilize the Azoteq ProxFusion evaluation kits and the CT210 configuration tool. The device communicates over I2C and can be configured using the IQS323 GUI to tune sensitivity, thresholds, and filter settings before embedding the parameters into the host microcontroller firmware.
