 I want to save audio files. I also want to retain information after the
power is off. We are using 8051, so the writing and reading speed is that
of the 8051. We also have a budget, to make it at a low cost.

Which 8051 are you intending on using ?

A standard (12x) 8051, or a 100Mhz 8051 ?

The writing and reading speed is a function of the device you decide to 
use, not the 8051.

Are the audio files going to be recorded by the 8051 or played back by 
the 8051 ?

If you use a Flash Card ( with an SPI interface ) does it need to be 
compatable with a PC ?

Do a google for 8051 + mp3 players.

You will find all forms of storage devices connected to 8051 devices.

Some can record audio some can not.

We can all keep guessing where this will lead or you can keep it to 
yourself.

The more information you give up front, the sooner you can get a real 
answer.

good luck

1 WHICH one of the 600 8051 variants are you using?


2 Is this a commercial project or one for collage?

3 What size budget do you have?

4 What sort of size production are you looking at?



5 SMS or TXT  grammar is usually refered to as WKS or Wanky Kid Speak 
and if David had not picked you up on it the other would have.  SMS 
grammar is fine for the phone to your mates but not when in a 
professional environment asking for help.
