AT76C113

2391BS–IMAGE–05/03

Description

The AT76C113 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

AT76C113 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

of hardware resources, controlled by ARM, perform digital camera functions such as

image DSP processing, JPEG coding/decoding, MPEG-1 coding/decoding, DMA

access to SDRAM, and video encoding. All these computationally-intensive functions

are implemented in hardware which can be programmed according to user specifica-

tions, thus allowing ARM to be free for other user-defined functions.

Part Versions

The AT76C113 device comes in six versions, each with slightly different features. These

are summarized in Table 1. In the rest of this document, the AT76C113-HU part is

discussed.
