Matrix Orbital is pleased to announce that the EVE Series has been updated to include the new BT81x ICs from Bridgetek. With the addition of the BT815 and BT816 ICs, Bridgetek has improved and extended the capabilities from the previous generations of FT8xx Embedded Video Engine (EVE) ICs. These new ICs provide engineers the ability to design and create dynamic Human Machine Interfaces (HMIs) with display, audio and touch support.


New features of the BT81x include memory management and system resource improvements, as well as, support for the Adaptive Scalable Texture Compression (ASTC) algorithm to provide significantly enhanced image quality without requiring additional bandwidth. With the dedicated QSPI host port, these ICs support external flash memory to extend the on-chip capacity for storing additional image and audio objects, including bitmaps and fonts.


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 imagesFT812 CPU
  • SPI/QSPI NOR 32Mb or 128Mb Flash to fetch graphic elements(image, font, widget etc)1 MB graphics RAM
  • 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
  • Support landscape and portrait orientations
  • Integrated 1MByte graphics RAM, no frame buffer RAM required
  • Support playback of motion-JPEG encoded AVI videos
  • Audio wave playback for mono 8-bit linear PCM, 4-bit ADPCM and µ-Law coding format at sampling frequencies from 8 kHz to 48 kHz. Built-in digital filter reduces the system design complexity of external filtering
  • PWM output for display backlight dimming control
  • Built-in Power-on-reset circuit
  • Extended Operating temperature range: -20oC to 70oC
  • RoHS compliant

Applications Include:

• Point of Sales Machines• Power meter
