The CY8C20424-12LQXI from Infineon is an 8-bit MCU based on the M8C core, running at 12MHz. It offers 8KB flash and 512B RAM, with a supply range of 2.4V to 5.25V. Packaged in a 32-UFQFN, it includes LVD, POR, and WDT, making it suitable for touch and industrial applications.

  • Wide voltage range (2.4V-5.25V): Works with both 3.3V and 5V systems.
  • M8C core with PSoC flexibility: Supports analog and digital peripherals.
  • Compact UFQFN package: Ideal for space-limited PCBs.
  • Integrated LVD and WDT: Enhances system reliability without extra components.

Capacitive Touch Interfaces

Infineon's PSoC architecture supports touch sensing, ideal for buttons and sliders in consumer devices.

Industrial Control Panels

With 5V operation and WDT, it can handle noisy industrial environments reliably.

LED Lighting Control

PWM outputs and 12MHz speed enable smooth dimming and color control.

Portable Instrumentation

Low power modes and 2.4V operation suit handheld meters.

Automotive Interior Switches

Wide voltage range and -40°C to 85°C rating support cabin control modules.

Smart Appliances

8KB flash is enough for washing machine or microwave control logic.
