Overview

The CY8C4024LQI-S412 is a member of the PSoC 4000S series, a 32-bit ARM Cortex-M0+ microcontroller designed for low-power operation and cost-effective mixed-signal integration. It operates at up to 24MHz and features 16KB of Flash memory and 2KB of RAM, specifically optimized for human-interface applications. The device is most notable for its CapSense technology, which provides high-performance capacitive sensing for buttons, sliders, and proximity sensors.

Why Choose This Part

This MCU stands out for its high-performance capacitive sensing (CapSense) that is highly resistant to noise and supports liquid tolerance. It offers significant flexibility through programmable analog blocks and a wide operating voltage range from 1.71V to 5.5V, allowing it to run directly from various battery chemistries or standard 5V rails. The ultra-low standby current of 2.5uA makes it ideal for energy-constrained designs.

Applications

Capacitive Touch Interfaces
Implementing robust touch controls, sliders, and proximity sensors in consumer appliances using the fourth-generation CapSense engine.
Industrial Sensor Nodes
Low-power sensing applications utilizing the 10-bit ADC and programmable analog blocks for signal conditioning.
Battery-Powered Wearables
Small form-factor devices requiring 2.5uA standby current and integrated analog peripherals to minimize PCB footprint.
Smart Lighting Control
Using PWM channels and I2C/UART connectivity to manage LED brightness and communicate with building automation systems.
