I dont know how to u se it or what it can do but can i use it in any way.
It was found in a old DVD player that the laser was failing so I took it apart.
Any info maybe how i could program it / use it would be very helpful.
thank you
You tried to search google
You tried to search google for a datasheet? That is all we would do to help.
well I found this about it
| Partname | EN29F040-70P |
| Description | 4 Megabit (512K x 8-bit) Flash Memory |

After long search I found this
and this was on a pdf file for EN29F040

I forgot to mention that I have neaver programed a thing so i am an abusulote noob at this kinda stuff
Just because I found this in a DVD player thats what got me intrested
And if you have some easyer chips to start of with that do not cost alot i would try but I am in school and dont have a after school job that i could use to pay for something expensive.
It says at the top its Flash
It says at the top its Flash Memory, so it stores info that other chips can access. Its not much use by itself.</p><p>An arduino or picaxe starter kit would be a good way to dive in to micros, or if youre reallY tight on money check out this instructable.
