AT76C113 Datasheet, PDF (2/4 Pages) ATMEL Corporation – High- Performance Digital Camera Processor

Description
Part Versions
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
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, 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.
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.
