FTDI Chip Unveils High Resolution EVE Devices for up to 800 x 600 Pixel Display Sizes

Delivering faster upload speeds, greater colour depth & improved video playback for next generation HMIs FTDI Chip’s highly-regarded Embedded Video Engine (EVE) portfolio for advanced human machine interface (HMI) implementation has been further strengthened with the introduction of 4 new ICs - the FT81xQ series.

These new EVE devices support higher maximum screen resolutions than previously possible - increasing from the 512x512 pixels of the company’s FT800Q/801Q offering up to 800x600 pixels, in order to address larger displays (7-inches and above) used in point-of-sales units, information kiosks, etc.

The FT810Q has 18-bit RGB interfacing and resistive touch functionality, while the FT811Q has 18-bit RGB interfacing and is designed for capacitive touchscreen implementation (with provision for 5-point touch detection).

These are complemented by the FT812Q and FT813Q for use respectively with resistive and capacitive touchscreens, but each with 24-bit RGB. As a direct result of algorithm enhancements, the devices in the FT81xQ series have much smoother video playback. Furthermore, screen rotation through 90° is far easier to achieve, permitting both landscape and portrait orientations - a clear benefit when these ICs are utilised in handheld designs. The memory capacity has also been increased from 256kBytes up to 1Mbytes and a quad SPI interface accelerates data transfer rates. Multiple palettes are supported, covering 16-bit and 32-bit colours with transparency.

Extra-large ROM fonts have also been added so that there is greater scope when it comes to using different text options. These devices are to a high degree code compatible with the previous generation of resistive (FT800) and capacitive (FT801) EVE ICs. Their features result in major performance improvements, with JPEG loading being 500 to 1000 times faster than previously possible and the ability to draw up to 16 pixels within every clock cycle (compared with 4 for the FT800/801 offering).

Firmware memory operations (such as copy, fill and CRC) are 2 to 4 times faster due to the tuned inner loops that have been utilized, while the CMD SNAPSHOT function is now hundreds of times faster. An analogue pin on the FT812/FT813 allows the monitoring of temperature or light data (for adjustment purposes) and can be used to detect the presence of sound. 

Acting as a companion chip to the system microcontroller, an EVE device will significantly simplify the implementation process, so that graphics are rendered line-by-line at 1/16th pixel resolution, rather than pixel-by-pixel - with the upshot that there is no longer a requirement for large Flash memories, frame buffers or high performance microcontrollers. Furthermore, the inclusion of both audio and touch control functionality dispenses with the need for separate controllers for each. Thanks to the combination of its object-oriented approach and high level of integration, EVE enables the development time, bill of materials cost, board space that are normally associated with HMI implementation to all be reduced dramatically.

The FT810Q and FT811Q are both supplied in 48-pin VQFN packages, while the FT812Q and FT813Q come in 56-pin VQFN packages. For more information on the FT81x series and other EVE devices go to:
