FTDI Introduces Easy-to-Use Graphic Controller for Wide-Ranging Display Applications

Targeted at cost-effective, intelligent QVGA and WQVGA TFT display panels, the FT800’s object oriented approach renders images in a line by line fashion with 1/16th of a pixel resolution, eliminating the expense of traditional frame buffer memory. Supporting 4-wire resistive touch sensing with built-in intelligent touch detection and an embedded audio processor allowing midi-like sounds combined with pulse code modulation (PCM) for audio playback, the controller’s functionality sets new industry benchmarks. The combination of display, audio, and touch on a single-chip solution enables engineers to produce graphic user interfaces (GUIs) that deliver compelling user experiences.

The object orientated approach means objects such as images, fonts and audio elements can be easily implemented and manipulated via a low pin count SPI or I2C interface. In order for the desired GUI to be realised, the engineer initialises the object memory (up to 256 kBytes) and then controls the specified objects and their attributes through construction and interaction of a small display list buffer. As a result of this, even low end (8-bit) microcontrollers can be used as the host processor if desired. Up to 2000 objects can be controlled within an 8k byte display list. Eliminating frame buffer memory and the need for a high end MCU, together with integrating touch and audio in a 48LD space-saving package, provides substantial system cost savings.

The FT800Q is capable of providing 24-bit (true colour) support on an 18-bit interface. It comes preloaded with a useful set of fonts and sounds on its ROM to further facilitate completion of the development process as quickly and easily as possible. Anti-aliasing mechanisms enhance the appearance of the display’s output when rendering lines and complex shapes or when implementing signatures on resistive touch screens. Built-in widgets mean that even complex objects (such as analogue clocks) can be implemented without difficulty, while ensuring a high quality image.

Supporting low power operation, the FT800 draws only 35 mA (typical) in active mode and 25 µA in sleep mode. It has a -40 °C to 85 °C operational temperature range and is packaged in a compact 7 mm x 7 mm x 0.9 mm 48-lead VQFN package.

“With EVE, FTDI Chip is redefining the cost/quality paradigm for GUI development and offering intelligent display solutions with far more competitive price points. The breadth of applications is extremely wide, allowing engineers to cost reduce current displays for point of sale equipment and printers, while enabling colour touch screen functionality to be added to thermostats, power meters, toys and common home appliances.” states Fred Dart, CEO and founder of FTDI Chip. “EVE marks a new stage in the evolution of FTDI Chip, taking our ability to generate innovative technology then applying it to new system areas to provide engineers with easy-to-use solutions of un-matched value.”

Pricing for the FT800 in quantities of 100k units is US $2.75. With the announcement, FTDI Chip is enlarging the scope of strategic customer engagements.
