The Infineon CY8C5668AXI-LP013 is a 32-bit ARM Cortex-M3 MCU running at 67MHz. It features 256KB flash and 64KB RAM, with a wide 1.71V to 5.5V supply range. The 100-LQFP package integrates CapSense, LCD, DMA, POR, PWM, and WDT. This PSoC 5LP device is ideal for touch-enabled consumer and industrial applications.

  • Integrated CapSense: Eliminates external touch controllers, reducing cost and board space.
  • Wide voltage range (1.71V-5.5V): Flexible for battery or 5V-powered designs.
  • ARM Cortex-M3 core: Industry-standard architecture with rich ecosystem support.
  • On-chip LCD driver: Simplifies display integration for user interfaces.

Smart Home Control Panels

CapSense enables sleek touch interfaces, while LCD driver supports local displays without external ICs.

Portable Medical Devices

Low 1.71V operation extends battery life in glucose meters and pulse oximeters.

Industrial HMI Keypads

CapSense works through gloves and moisture, ideal for factory floor terminals.

Consumer Appliances

5.5V tolerance simplifies interfacing with legacy sensors and relays in washing machines.

IoT Sensor Nodes

DMA and low-power modes enable efficient data aggregation from multiple sensors.

Automotive Interior Lighting

PWM channels control RGB LEDs, while WDT ensures fail-safe operation in dashboards.
