lol.... I was starting to work on it, then I got busy again. I got them for $20 each.
I have plenty of pictures and I dug up most of the documents. But you are correct on the AT76 family. AT76C113PU is the CPU. The unit is On-The-GO Host/Slave which is nice. I think it is the MPIX Atmel Playing Processor. Around 84 Mhz and is made for image decoding/processing.
I think the parts are dicontinued and were replaced by the AT76C120 and/or 114P, but I am not sure. I think they have an SDK, and I heard they had problems with the USB's MSC but fixed it in a later revision.
From their brochure:
Digital Camera Solutions
Imaging Multimedia and Digital Broadcasting
AT76C113PU-0Z208: Playback, <2-Mpixel, 128-Mbyte Maximum SDRAM, USB Host
Some of the things I have heard:
Arm Icebreaker inputs (one end has a nice set of holes for a Jtag header)
Outputs: Video, LCD, VDAC and RGBDAC
Audio out, SPU, USART (IR targeted), USB Host/Slave
MMC/SD via SPI, Memorystick, SSFDC.
Codecs: BCH (flash), JPEG (<200 ms for 2 Megapixels), MPEG1
8K Program/Data CacheRTC, Watchdog timer, and some onboard RAM
Supposedly it might have some ADC and a DAC.
Unified Memory structure
I am booked for the next week, but my order to Mouser, Jameco, or Digi-key should be placed I and will be getting some things that will help better.
Sorry for any typos, but I am in a rush.
