Title: Microcontroller as USB drive
Post by: Razor Concepts on June 08, 2010, 05:20:34 PM

I am looking for some kind of microcontroller that reads data from a SD card, and when plugged into a computer, will show up as a flash drive. I am open to any microcontroller, not just little 8 bit avr or pic. I need these specs:

• 3.3v supply voltage
• SMD package with pins (no BGAs or QFN)
• ADC
• Preferably no crystal required

Thanks all! Example projects with open-source code would help greatly.

I believe there are some PICs that meet your requirements.
