eeprom FM27C512 errase

[vanos batam]

hello all...how i can do erase this eeprom without eeprom eraser tool..i need erase it manual. any metod ?

[PeterOBD]

clear window and take under direct sunlight for a several minute

[vanos batam]

ready try it.
but not erase this eeprom.. any other metod?

[Zmann]

Sunlight needs seven days not several minutes.

it needs normal UV lamp, can be the one from some water filtering apparatus. need very close distance of an inch placing

[PeterOBD]

it works in europe, tested by me years ago.
it must works in indonesia much better, only must wait for direct sunlight, clouds /vapor/ is effective UV filter.
some wery old types needs little bit higher energy to excitation but i believe it no needs more than hour under indonesian sun :)
if you are looking for available UV source, look at local supplyer for medicinal technic, i have tube from germicide emitter /10usd/. may be it would be usable cheap UV checker for banknote or some UV LED, but needs to check datasheets if spectrum contains some energy in UV-C /220-280nm/, because with standart "UV" LED operating time is tens hours.

[vanos batam]

but in Indonesia was a rainy, no sun is too bright

[gadroulll]

no other method try to use eeprom 27c512 that can been erased electrical

[Meat-Head]

can confirm bank note checker erases approx 10 mins.

we left on 20 mins

The real thing would be something like this: UV Eprom Eraser Erase Ultraviolet Light Erasable Timer | eBay (http://www.ebay.de/itm/UV-Eprom-Eraser-Erase-Ultraviolet-Light-Erasable-Timer-/320748419972?pt=LH_DefaultDomain_3&hash=item4aae187b84#ht_3991wt_906)

Maybe a "tanning bed" would help, too.

I wouldn't do it with a magnify glass, your'll end up cooking it

[vanos batam]

Thank you all.....BUT i got this problem now
after writing 100% but verify error..
what wrong?

[vanos batam]

This is where I want to dump the write to the eeprom 27C512

Yes agree, but that thumb looks like a lorry drivers or shelf stackers thumb.

You need the data sheet for that chip.

When i was growing up (no lie - serious) Daddy (before he died) told me this:

EPROMS require 25 Volts to programme them, cmos ones can do it on
12.5 volt.

Check the data sheet for that chip

[ghauman]

it may also be the eprom not being full erased with the magnifier.
if its not completely erased yoy will end up having programming errors.

MeatWhat a good Daddy. :manuflag: I'm very envy.
The 25V is require for older eproms.

Thank you all.....BUT i got this problem now
after writing 100% but verify error..
what wrong?

Do you have Willem Programmer or a Beeprog ori/clone?


Does that software works on a Genius G540 programmer?


Thanks
