Description The AT76C110 is a highly integrated solution for digital cameras. It combines a number of functions that are required in implementing 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 computation-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. Features • DSP Functions for CCD/CMOS Image Processing • Video Encoder, Including Line Driver for NTSC/PAL TV Signal • Baseline JPEG Compression/Decompression • SDRAM Interface • Support for All Flash Card Interfaces (Atmel DataFlash®, MMC, SSFDC, Compact Flash) • Integrated DACs for LCD • USB and USART Interfaces for PC Camera Applications • Small-Segment LCD Driver • 32 Pins for General-purpose I/O • 5 External Interrupts, Timer Clock Input and Wake-up Pin • DACs for Camera Control Functions and Audio Output • ADCs for Monitoring Camera Analog Inputs, Audio Input and Switch Input, Like Window Comparator • Serial Interface for Controlling Camera Components • Up to 2M Bytes Program Space • Support for RTOS • All Low-level Software, Application Samples are Provided • Built-in Outputs Include a CVBS Output with a Line Driver, YC16-bit Digital Output, RGB 565 Digital Output, Digital Composite Output and RGB Analog Output • Compatible with Various Types of Display Devices • SDRAM Support from 16M Bits to 256M Bits • Direct Interface to Epson and UNIPAC LCDs • 280-pin FlexBGA Package • 3.3-volt Core and I/O Operation
