FTDI Chip ventured into a new application sector beyond the USB semiconductor and software solutions it is best known for. Addressing the need for ever more advanced forms of human-machine interaction, the company announced the release of the FT800, the initial offering in its Embedded Video Engine (EVE) family.
Targeted at cost-effective, intelligent QVGA and WQVGA TFT display panels, the IC’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.
The controller supports 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 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.
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 analog clocks) can be implemented without difficulty, while ensuring high image quality.
Supporting low-power operation, the IC draws only 35 mA 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 x 7 x 0,9 mm 48-lead VQFN package.
