AT76C110 Datasheet
Description
Capabilities
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.
• 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)
• 100 - 150 mA current
• 1 - 5 mA in standby mode
• 50 µA current in sleep mode
