Bridgetek BT815/BT816 Advanced EVEs

Author : Bridgetek Published Time : 2018-10-24

Bridgetek BT815/BT816 Advanced Embedded Video Engines (EVE) builds 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. Support for the Adaptive Scalable Texture Compression (ASTC) algorithm means that image quality can be significantly enhanced without needing greater bandwidth to be allocated as the compression algorithm allows for smaller compressed files, thus providing the ability to enable major savings in memory space required when it comes to larger fonts and data-heavy images.

Features

BT815/BT816 functionality includes graphics control, audio control, and touch control interfaceSupport multiple widgets for simplified design implementationSupport Adaptive Scalable Texture Compression (ASTC) format to save considerable memory space for larger fonts and graphics imagesSupport external QSPI NOR flash to fetch graphic elements(image, font, widget etc)Support 4-wire resistive touch screen (BT816)Support the capacitive touchscreen with up to 5 touches detection (BT815)Hardware engine can recognize touch tags and track touch movementHardware engine provides notification for up to 255 touch tagsProgrammable interrupt controller provides interrupts to host MCUBuilt-in 12MHz crystal oscillator with PLL providing programmable system clock up to 72MHzVideo RGB parallel output; configurable to support PCLK up to 60MHz and R/G/B output of 1 to 8 bitsProgrammable timing to adjust HSYNC and VSYNC timing, enabling interface to numerous displays
