Description

The AT76C112 is a highly integrated solution for digital camera and image playback devices. It combines a number of functions that are required for implementing such devices.
• Image data acquisition from CMOS imagers
• Image display
• Image processing and image storing
• Overall system 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 equipment manufacturers to directly access a variety of devices that may be present in a digital camera or image playback system.
• Communication with PCs
• Communication with Flash cards
• Serial communication ports for controlling other devices in the system
The AT76C112 design is based on an ARM^® microprocessor that controls the entire chip. A number of hardware resources, controlled by ARM, perform digital imaging functions such as JPEG coding/decoding, image resizing, and DMA access to SDRAM. 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.
