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
