Using the HOLTEK HT27C512-70 w/ the Arduino ?

Hello everyone !

Yesterday I recieved my Experimentation kit from Adafruit just yesterday and I already finished all the experiments :stuck_out_tongue:
I'm currently working on my own tiny project.

Anyway, some month ago, before throwing away an old video card, I poped away one of the chips very carefully. I just wanted to keep it for decoration. But know that I have recieved my Arduino, I'm wondering if I can actually use this chip (even if it's for making ultra simple calculations or something.

The chip have the following line wirtten on it:

HOLTEK
HT27C512-70
A119K0851-2

I made a few research and I think I maybe found some sort of datasheet for it.

However, since I'm a beginner, it doesn't talk to me that much. So I'm asking you if indeed this chip can be used with the Arduino and if a beginner can play with it with some simple code or something.

Thank you very much in advance for you answers !

Short answer. No

The HT27C512 chip family is a low-power,
512K bit, +5V electrically one-time programmable
(OTP) read-only memories (EPROM).

Its a one time programmable, so its already got stuff in it.

Thanks for your answer.

This is indeed what I've figured out, I was quite disapointed. However as it seems to work like an EEPROM (instead that it's not programmable) IO was wondering if I was theorically able to dump the content of it with the Arduino.

Unfortunately I'm not experienced enough to do it and I'm not really able to fin a proper tutorial about EEPROM dumping w/ the Arduino.
