The CY8C4024LQI-S411T from Infineon is a 32-bit MCU based on the ARM Cortex-M0+ core running at 24MHz. It features 16KB flash and 2KB RAM, with a supply range of 1.71V to 5.5V. The 24-UFQFN package integrates CapSense, LCD, LVD, POR, PWM, and WDT, making it a versatile choice for touch and low-power applications.

  • CapSense integration: No external touch IC needed.
  • Ultra-low power: 1.71V operation ideal for battery devices.
  • Small size: 24-UFQFN saves board space.
  • Multi-function: LCD, PWM, and WDT in one chip.

Touch-Sensitive User Interfaces

CapSense with 24MHz Cortex-M0+ enables low-power, reliable touch buttons.

Wearable Devices

Ultra-low 1.71V operation and small UFQFN package fit compact designs.
