Touch display controller ICs with Embedded Video Engine (EVE)

EVE technology is a revolutionary concept that utilizes an object oriented methodology for creating hi-quality human machine interfaces (HMIs). With support for display, audio, and touch, this new technology allows engineers to quickly and efficiently design HMIs and deliver robust solutions, hi-resolution displays with lower bill of material costs.

Building on the success of the first two generations of FT8xx touch display controller ICs with Embedded Video Engine (EVE) technology, the series has now been extended to include a further two graphics controller devices which offer a plethora of improvements and extended capabilities, the BT81x series.

Key Hardware Features:

  • BT815/6 functionality includes graphic control, audio control, and touch control interface.
  • Support multiple widgets for simplified design implementation
  • Support Adaptive Scalable Texture Compression (ASTC) format to save considerable memory space for larger fonts and graphics images
  • Support external QSPI NOR flash to fetch graphic elements(image, font, widget etc)
  • Support 4-wire resistive touch screen (BT816)
  • Support capacitive touch screen with up to 5 touches detection (BT815)
  • Hardware engine can recognize touch tags and track touch movement. Provides notification for up to 255 touch tags.
  • Programmable interrupt controller provides interrupts to host MCU
  • Built-in 12MHz crystal oscillator with PLL providing programmable system clock up to 72MHz
  • Video RGB parallel output; configurable to support PCLK up to 60MHz and R/G/B output of 1 to 8 bits
