i want to know about a seller of MBED-IF01 CHIP.........

i cannot find the chip at digikey~

i just want to know the manufacturer and where can I get the chip????

We have designed a unit incorporating a MBED and now I wanted to put it all on a single pcb not using some of the Mbed functionality to keep costs down. Seems I am a bit stuffed without the MBED IF01 being sold. Will it ever be available?

The mbed module is really intended for prototyping or small series. When you want to do series or need to cut cost it may be best to use a dedicated design and remove or replace the i/f chip. A low cost lpc11u35 based hdk or even a usb to serial converter like ftdi232 or pl2303 may be the cheaper option.

The interface chip is (currently) not sold. There is the HDK, which gives a simplified version of that functionality: http://mbed.org/handbook/mbed-HDK. I believe soonish the source code would be released. Compared to the mbed interface chip it lacks for example Local File System support.

I don't know why that is, although I could imagine they consider the method used to implement the file system not the nicest possible solution.

What *is* the current interface chip? Is it a custom FPGA?

AFAIK it is just a microcontroller.

It's an NXP microcontroller of some kind, the NXP logo on mine survived the etching/obfuscation process. I think I remember reading somewhere that it's an LPC2368, but I don't remember where.

The LPC2368 is the prototype mbed, before the LPC1768 came. The HDK is for the LPC11u35, so good chance that is also what the chip is. It would make sense functionality wise I guess.
