The Infineon CY8C5688AXI-LP099 is a 32-bit MCU with an ARM Cortex-M3 core running at 80MHz. It features 256KB flash and 64KB RAM, operating from 1.71V to 5.5V. The device includes CapSense, DMA, LCD, POR, PWM, and WDT peripherals. Housed in a 100-LQFP package, it operates from -40°C to 85°C, making it ideal for consumer, industrial, and medical applications.

  • Integrated CapSense: Provides reliable touch sensing without external components.
  • Ultra-low voltage operation (1.71V): Enables direct battery-powered designs.
  • Rich analog/digital peripherals: DMA, LCD, PWM, and WDT for versatile system design.
  • Compact 100-LQFP package: Saves PCB space for space-constrained products.

Touch-Sensitive Control Panels

Integrated CapSense eliminates external touch ICs, reducing BOM cost and board space.

Portable Medical Devices

Low voltage (1.71V) and low power extend battery life in glucose meters and pulse oximeters.

Smart Home Thermostats

LCD drive and PWM control display and fan speed, while CapSense handles user input.

Industrial HMI

DMA and PWM enable smooth animations and motor control in operator panels.

Wearable Fitness Trackers

Small 100-LQFP package and 80MHz core support sensor fusion and BLE connectivity.

Automotive Interior Lighting

Wide voltage range and PWM control RGB LEDs for ambient lighting systems.
