Overview

The CY8C4024LQI-S411 is a member of the PSoC 4000S series, featuring an Arm Cortex-M0+ core running at up to 24MHz. This microcontroller integrates Infineon's fourth-generation CapSense technology, providing advanced capacitive sensing for touch interfaces with high signal-to-noise ratios and water tolerance.

Why Choose This Part

This PSoC 4 device offers programmable analog and digital blocks, including two IDACs and low-power comparators that remain active in Deep Sleep. Its CapSense sigma-delta (CSD) block delivers superior noise immunity (>5:1 SNR), making it highly reliable in electrically noisy environments or applications involving moisture.

Applications

Capacitive Touch Interfaces
Implementing buttons, sliders, and proximity sensors in consumer and industrial panels with SmartSense auto-tuning.
Low-Power Sensing Nodes
Utilizing the 2.5 microamp Deep Sleep mode for battery-operated devices that require periodic wake-up or comparator-based monitoring.
Human-Machine Interface (HMI)
Integrating LCD segment drive and touch control into a single chip for small appliances and thermostats.
