Human Machine Interface (HMI) for Appliances

As modern appliances evolve to meet rising consumer expectations for connectivity, convenience, and intuitive operation, human machine interfaces (HMIs) have become essential for delivering clear control and feedback. These interfaces often include touchscreens, displays, haptic feedback, sound cues, and even voice control to enhance usability.

This appliance HMI system addresses growing market demands with a flexible portfolio of variants, ranging from high-end systems featuring large displays and advanced wireless connectivity to mid-range options equipped with NFC authentication for secure access and control.

Designed with support haptics-compatible touch panels, voice guidance, and multi-modal input, this system enables seamless interaction across a wide range of appliances. Integrated LCDs showcase rich GUIs and status screens, while high-end variants with Wi-Fi and Bluetooth^® Low Energy (LE) ensure effortless pairing with smartphones and integration into smart home ecosystems.

System Benefits:

• Flexible portfolio with multiple system configurations to meet diverse appliance use cases and design requirements.
• High-end variants support large, high-resolution displays with precise video rendering and integrated wireless connectivity (Wi-Fi/Bluetooth LE) for seamless smart home integration.
  • High-resolution LCD operates without the need for external DRAM, simplifying PCB design and reducing BOM costs.
  • Integrated PMIC consolidates power delivery from a single 5V input and includes advanced protections, such as undervoltage lockout (UVLO), overcurrent protection (OCP), and thermal protection.
• Mid-range variant includes NFC-based personal authentication for secure access, ideal for shared appliance environments.
• Robust software development ecosystem.
  • Supports multiple real-time operating systems (FreeRTOS, Azure RTOS) and popular graphics libraries (LVGL, GUIX) for flexible UI development.
  • Flexible Software Package (FSP) streamlines code configuration and peripheral setup for faster time to market.
