Bridgetek BT817/8 Advanced Embedded Video Engines

Bridgetek BT817/8 Advanced Embedded Video Engines (EVE) are easy-to-use graphic controllers designed for embedded applications to generate high-quality human machine interfaces (HMIs). The BT818 supports a 4-wire resistive touch screen while the BT817 supports a capacitive touch screen with up to 5 touchpoint detection. The BT817/8 series offers high-resolution graphics and video playback that allows users with little expertise to create high-quality displays. The modules support I/O voltage from 1.8V to 3.3V, and an internal voltage regulator supplies 1.2V to the digital core. Bridgetek BT817/8 Advanced Embedded Video Engines are available in a compact lead-free, VQFN-64 package and have an extended operating temperature range of -40°C to +85°C.
