How to use Winbond W27C020-70 EEPROM with arduino?

Other Hardware Storage

Hi there,
I have Winbond W27C020-70 EEPROM which I got from old electronics. I want to use it with arduino to store data. Is there any way to use this EEPROM with arduino? If I can use this EEPROM with arduino then how can I connect with it arduino? Any help would greatly appreciated.

Here is the datasheet for W27C020-70 EEPROM

not easily.

you need a 12V programming voltage,

18 bits of address
8 bits of data
_WR,_RD,_CE,_PGM control pins

this totals to 30 I/O pins, the UNO has 20. So you would need some type of I/O expander.
this 'free' chip only gives you 256k of storage.

I would recommend using I2C EEPROMS. The AT24CM02 is has 256k of storage, Uses the I2C bus (2pins)
here is a link AT24CM02 I2C 256k x 8 EEPROM
