AT76C111 is a low-power digital camera control chip that integrates DSP and video encoder, supports SDRAM and various storage cards, and can be widely used in consumer digital cameras, portable digital camcorders, industrial vision systems, etc.
The AT76C111 is a highly‑integrated microcontroller designed for digital camera applications. It combines image acquisition, processing, storage, display and camera management functions, and is built around an ARM® core that handles the heavy‑weight DSP and JPEG tasks in hardware.
Key features include multiple flash‑card interfaces, USB and USART connectivity, up to 2 MB of external Flash for program space, optional 2 MB SRAM, SDRAM support from 16 M‑bit to 256 M‑bit, and low power consumption modes. The device supports CCD or CMOS sensors up to 16 MP and provides video encoding for NTSC/PAL output.
