Discover the New 4th Generation EVE Graphics Controller IC

The new BT817 and BT818 series represent the fourth generation of EVE products, and follow the already established mantra of helping engineers with little or no relevant prior experience to build advanced HMIs with high degrees of differentiation.
These new functionally-superior graphic controller ICs are intended for use in retail, digital signage and office management systems, as well as public information units, vending machines, domestic appliances, store/mall direction finding systems, training/educational equipment and interactive exhibits. They are able to address the requirements of HMIs rendered on much larger format displays and offer greater resolution levels too.

Features: 

  • Advanced Embedded Video Engine (EVE) with high resolution graphics and video playback
  • Graphic control, audio control, and touch control interface
  • Supports multiple widgets for simplified design implementation
  • Built-in graphics operations allow users with little expertise to create high-quality displays
  • Supports Adaptive Scalable Texture Compression (ASTC) format to save considerable memory space for larger fonts and graphics images
  • Supports external QSPI NOR flash up to 2Gbit to store and fetch graphic elements (image, font, widget etc.)
  • Supports 4-wire resistive touch screen (BT818)
  • Supports capacitive touch screen with up to 5 touch point detection (BT817)
  • Hardware engine can recognize touch tags and track touch movement. Provides notification for up to 255 touch tags
  • Enhanced sketch processing
