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.

Our newly added BT817 and BT818 series represent the company’s fourth generation of EVE products, and follow the already established mantra of helping those 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.


Building on the success of the first three 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.

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.

Further memory management and system resource improvements are available in the form of a dedicated QSPI host port for attaching an external flash memory, to supplement the EVE controller’s on-chip memory. The dedicated port is used exclusively for accessing external memory thus extending the on-chip capacity to store additional image and audio objects such as bitmaps and fonts required in many feature rich displays. As an additional port this frees up the main system QSPI port used to control the BT81X devices from memory copy tasks and as such reduces the workload on the system MCU.
