Atmel Microcontroller as USB Data Stick... Good or Bad

[ngcoders]

Hello

I need to build a kind of pen drive with ability to store say max 10 Kb of data. The data is critical in nature.

As i am already clued with AVR's i am of the opinion , a simple AVR based circuit with USB boot loader would do the trick.

The bootloader would allow me to read and write on the Flash and anything like ATmega168 would suffice in terms of storage.It will be USB 1.1 but speed is not the concern here.

The Atmega + bootloader allows me a single chip solution and packaging into a Pen drive package. Something like AVR Stick from SparkFun.And the solution will be very cheap.

Do you forsee any problems with this idea if used commercially. Or any better ideas ?

Thank you in Advance

How are you planning to interface to the USB port? Are you using external hardware or software?

Some avr's already have USB capability built in.

I will be using VUSB driver on ATmel AVR side and use the normal Atmega series as a place to store data.

The USB interface will 1.1 though slow is good enough for me. LibUSB driver on the PC side ( Linux / Windows / Mac support ).

Im curious if any problems will be faced ... or any better ways to do it.

Hi

Atmel have published application note for the SAM3U micro, for acting as a USB data stick

It use an ATMEL arm SAM3u micro controller and a lash memory IC

Where can I find this appnote ? There is no such document on atmel's website...

Hi

See ATMEL application code for the SAM3U in atmel site

One of the files is a source code for memory steak works on the ATMEL SAM3U board

All the best
