FTDI EVE

FTDI EVE

EVE2 (FT81X) Series

The first device in the series, the FT800, launched in 2013 and took the titles of British Engineering Excellence ‘Electronic Product of the Year’ and Elektra ‘Digital Semiconductor of the year’, within the same year, where the product was described as providing ‘versatility and innovation’ and ‘the technological capabilities with efficiencies that differentiate it from its competitors’. With its revolutionary EVE technology deploying an object-oriented approach, the series is capable of simplifying the implementation of intelligent displays – reducing bill of material costs, power budget, board space, and development time.


The FT81X series chips are graphics controllers with add-on features such as audio playback and touch capabilities. They consist of a rich set of graphics objects (primitive and widgets) that can be used for displaying various menus and screen shots for a range of products including home appliances, toys, industrial machinery, home automation, elevators, and many more.
