Graphic display controllers for development of HMI applications

RS Components has added two new graphic display controller ICs from Bridgetek that target the development of next-generation graphics displays for HMI applications. The BT815/816 controllers are the third generation of EVE devices. Providing support for audio, display and touch capabilities, they allow engineers to quickly and efficiently produce high-resolution displays and robust HMI solutions with a lower BOM cost. The innovative architecture used in the series can support adding display abilities to a broad range of 8, 16, or 32-bit enabled MCU systems, over a simple SPI interface. Making use of an object-oriented method to produce the final displayed image which is rendered line by line the EVE solution expedites the rapid progress of static and animated displays with full touch control and no expensive frame-grabbing memory on the BOM. New with the series is the additional dedicated Flash port, complementing the on-chip 1Mbyte RAM, for storing and accessing further display assets without affecting system design bandwidth. Other key features include digital audio output pin, extended command set including the new Flash memory access, bitmap rotation around a user-defined point, and Unicode string support. Offering an operating temperature range from –40C to +85C, the series devices are packaged in 64-pin VQFNs.
