Sandisk has a new product on the market looking to be hacked:

http://www.sandisk.com/retail/spa.asp


the unit has a Atmel AT76C113 cpu which is has a ARM7TDMI core (no mmu).
it comes with 2MByte flash (Atmel AT49BV162A) and 16MByte ram(ISSI IS42S16800A).
it uses the WM8728 DAC for audio http://www.wolfsonmicro.com/products/WM8728/
jtag is present on the board in a standard ARM 14 pin .1" header.
the unit also has both host and slave USB.
the unit works with a 5v regulated wall-wart.

average retail price i found was $39.99 with some as low as $31.99

the arm7tdmi core is already very well supported in the uclinux tree as
well as other small OS's such as eCos. the flash and ram sizes are plenty
for a bootloader, kernel, and initial ramdisk. the rest of the apps could
be pulled from one of the many card interfaces(such as the two CF slots).

Sounds intresting. Do you have a board scan that we can take a look at? Is the serial port brought out too?

I looked at the Atmel web site and they dont have the datasheet for the SoC, just a summary datasheet. Problem is Atmel does not like to publish the datasheets for specific ARM7 SoC parts (AT76 series) other than the general purpose ARM7 parts. I'm sure that these parts are based on or are similar to the AT91 family. Do you think that the current uClinux port will work with the AT76C113?

I dont think you can get an easier way to update the firmware than that! ;)

This would be a killer device if uClinux can work on it (Video, USB host, and audio for $39!). What is the clock speed on the amtel?

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.

I too am wondering if any further developments have been made.

Is the core arm7 or arm9? There's an Atmel '02 sales conference ppt floating around the 'net with the roadmap for the AT76C11x line. It claims that the AT76C113 will be arm9 based.

BTW, the firmware update on the Sandisk site may not be compressed. Strings shows lots of output.

Has anyone gotten any farther with this device is the past few weeks? This thing has the potential to be a great ultra-low-end wearable computing platform and/or low-end emulator engine for old video games. Anything that can be done to hack this box would be appreciated.
