2 / 3 page 2 AT76C111 2334AS–IMAGE–08/02 Description The AT76C111 is a highly-integrated solution for digital cameras. It combines a number of functions that are required in digital cameras. • Image data acquisition and capturing from either CCD or CMOS imagers • Image display • Image processing and image storing • Overall camera management • Control of general-purpose I/O functions • Data communication • Control of user functions • On-screen Display It also provides a large number of interfaces that allow camera manufacturers to directly access a variety of devices that may be present in a digital camera. • Communication with PCs • Communication with Flash cards • Serial communication ports for controlling other devices in the camera The design is based on an ARM® microprocessor that controls the entire chip. A number of hardware resources, controlled by ARM, perform digital camera functions such as image DSP processing, JPEG coding/decoding, DMA access to SDRAM and Video encoding. All these computational-intensive functions are implemented in hardware which can be programmed according to user specifications, thus allowing ARM to be free for other user-defined functions. Capabilities • Supports up to 16 megapixel CCDs/CMOS (10 - 30 MHz CCDs) • CCD colors are limited to the Bayer arrangements of the RGB primary colors • Interfaces to 16 - 256-Mbit SDRAM, one or two pieces • 30 frames/sec Video Display mode (NTSC) • 15 frames/sec Capture mode (VGA resolution) • Up to 1.5M bytes/sec read/write from/to Flash cards • 2M Bytes external Flash ROM for program space • 2M Bytes external SRAM for program/working space (optional) • Full-speed USB interface (mass storage and image class) • 60 - 100 mA current • 1 - 5 mA in Standby mode • 50 µA current in Sleep mode |
