SSD1926 Datasheet | Solomon Systech

DESCRIPTION SSD1926 is an image processor designed for advanced car AV device with image capture and process features . The image files can be saved into SD/MMC card through SD interface. The JPEG file is retrieved back from SD/MMC card, decoded and displayed on LCD panel through LCD interface. This interface supports various kinds of LCD panel like STN, CSTN and TFT. The LCD controller of SSD1926 supports LCD panel for mobile phone with size, for example, 176x220 and 240x160 resolution at color depth 1, 2, 4, 8, 16 and 32 bit-per-pixel (bpp). For 16 and 32 bpp, SSD1926 provides 2D graphics acceleration features like virtual display, image rotation, cursor display, line drawing, Bit BLT with raster operation, color fill, color expansion etc. SSD1926 is able to interface different type of generic microcontrollers that are popular in handheld devices market. It also support indirect addressing mode which can minimize the pin count of control signals. Internal PLLs is built such that only single clock is required for SSD1926 to generate clocks for blocks with various clock speed requirement. With advanced power management design, SSD1926 is suitable for low power consumption and advanced image applications etc. The SSD1926 is available in LQFP package. 2 FEATURES The main features of the SSD1926 are as follows: 2.1 Hardware JPEG decoder - Hardware decoder to decode JPEG image with variable size up to 1280 x 1024. - JPEG decoder is consisted of the following hardware module a. Discrete Cosine Transform (DCT) and Inverse Discrete Cosine Transform (i DCT) b. Quantization calculation with table downloadable by software c. Zigzag and run-length coding d. Huffman decoding with table downloadable by software - For viewing JPEG image on LCD panel, the JPEG decoder can decimate and crop the image such that the length is in multiple of 8. 2.2 2D Graphic Engine - Screen panning and scrolling - virtual display mode - Image rotation including 0, 90, 180, 270 degree - Two cursors...
