Texas Instruments is targeting its lowest-cost digital media processor, the TMS320DM335, at applications driven by advanced image capture and display requirements. The processor is set to enable enhanced user interaction with electronic devices such as Internet radio, e-books, video surveillance products and digital telescopes through feature-rich graphical user interfaces (GUIs). Powered by an ARM926EJ-S core running up to 270 MHz, the DM335 integrates a video processing subsystem (VPSS) to allow developers to add high-definition video display at 720p to new portable applications.
Through user interface technology, such as a four-level on-screen display, developers are able to create picture-within-picture and video-within-video as well as innovative GUIs. This is especially desirable for portable products that require the use of button or touch screens, such as portable karaoke, universal remote controls, video doorbells and electronic gaming applications.
For crisp and vibrant display images, the DM335 supports CCD/CMOS image sensors, resize capability and video analytics. The 1280-by-960-pixel digital LCD connection runs on a 75 MHz pixel clock and supports TV composite output for increased expandability.
The DM335 employs peripherals such as high speed USB 2.0 on-the-go, external memory interface (EMIF), mobile DDR/DDR2, two SDIO ports, three UART Ports, three SPI Ports and SLC/MCL NAND Flash memory support. In addition, customers can leverage TI’s HPA portable audio solutions including low-power codecs and amplifiers.
