Apparently an AVR with bad-ass USB device port on-chip. :P

Quote:
The AT76C711’s architecture consists of a USB Interface with a devoted DMA controller for fast transfers of data between the endpoint FIFOs and the DPRAM, a 2KB internal RAM, a Synchronous Peripheral Interface (SPI), a UART supporting maximum rate of 921 Kbaud, an 8x16-bit in-system SRAM for microcode storage (which is loaded from the SPI controller), 2K dual-port RAM (DPRAM) and a programmable DMA controller for packet transfers between the UART and the DPRAM without microcontroller intervention.

This looks really cool, but I have never heard of this before, not even at any of the Atmel seminars..

Check out the link, there is a datasheet available also..

nope, sorry, it seems no datasheet available after all..

The only mention of the chip is in an old "selection guide flyer" published by Atmel way back in 2003..

strange.. Seems they changed their mind.. :(

Download the flyer here:

http://www.atmel.com/dyn/resources/prod_documents/doc4004.pdf

there are lots more devices in there I have never heard of before.

Stuff like secure AVRs with partnumbers like:
AT90SC19236R
AT90SC19264RC
AT90SC25672R
AT90SC320856
AT90SC3232CS
AT90SC4816R
AT90SC4816RS
AT90SC6404R
AT90SC6432R
AT90SC6464C
AT90SC6464C
AT90SC9608RC
AT90SC9616RC
AT90SC9636RC
AT97SC3201

what in the world is going on here...

Hi,

I have a development board here. For this micro. A lot of the features we expected did not work when we got it. So we plumped for another solution. It was basically at908515 with sram memory instead of flash, that loaded its code from a atmel dataflash chip, which you had to program seperately, due to a bug in the chip you couldn't update the dataflash via the usb port, which was what we wanted to be able to do. It would have been perfect for us if it had worked :)

Maybe they decided that bug was a setback too :)
