The CY8C4013LQI-411 from Cypress is a low-power ARM Cortex-M0 MCU running at 16MHz. It features 8KB flash and 2KB RAM in a tiny 16-UFQFN package. With 1.71V to 5.5V operation, it includes brown-out detect, POR, PWM, and WDT. Designed for compact human-interface applications.

  • Ultra-wide 1.71V-5.5V supply – flexible for battery or USB power.
  • 16-UFQFN tiny footprint – ideal for space-limited PCBs.
  • Integrated PWM – simplifies LED and motor control.
  • Low-power Cortex-M0 – extends battery life in wearables.

Proximity Sensing

CapSense-capable GPIOs and 16MHz Cortex-M0 enable touch buttons in 16-UFQFN for wearables.

LED Lighting Control

PWM outputs and 5.5V operation drive RGB LEDs in decorative lighting strips.

Battery Chargers
