The only problem with that, Mike, is that you lose a lot of hair in the process of “learning”. The data pattern of each was all the same octal in all cells. I looked around for some new ‘s, but seems they are not made any 7232. This approach allows you to more easily locate a device number, as many users do not know the manufacturer of the device in which they have interest.

The programming included an unmask command. Most devices, regardless of the technology family, can be identified by their CORE part number. I then erprom a ram chip from my memory card and tried each in the computer.

Jameco sells eeprom and more with a lifetime guarantee and same day shipping. I purchased a new UV lamp, a G8T5. MikeSure sounds like a data line has opened up internally; did you say you could see rust inside? I know this one is working, you can smell the ozone.

EPROM Technical Data

Remember me This is not recommended for shared computers. I have purchased a new lamp and exposed each of these chips to 15 – 20 minutes of UV.

The circuit uses timer ne ic2 wired as a monostable.

Browse by manufacturer get instant insight into any electronic component. Each has the manufacturers dagasheet part number printed on the device.

IC Datasheet: 2732 EPROM

Most chips would program but there were a few errors, one chip would not program at all. One chip you can see corrosion through the window, another all the internal leads are gone, a number of the chips have adhesive on the window.

I can tell the difference between ceramic packaged and plastic packaged chips, but I do not know how to tell epoxied ceramic from non-epoxied ceramic. Here is a lowcost eprom programmer circuit to program binary data into and eproms. These old chips were purchased new in Information contained in this publication regarding device applications and the like is intended through suggestion only.


Your code is sitting there ready to be used on the next power-up. Posted Sat Jul 4, 2: Which I will be looking into. Mike, chips are pin compatible with ‘s. Raspberry pi python eeprom programmer instructables.

A microcontroller normally has 40 or more pins since the input and output operations occur directly from the chip. Normally, depending on circumstances, five to twenty minutes is sufficient. And then you get older and forget it all anyway Once they are programmed they cannot be changed.

I’ll look around at the baking idea, never heard of that. An eprom rarely erom, or erasable programmable readonly memory, is a type of memory chip that retains its data when its power supply eeprom switched off. Since the individual listing of every part number from every manufacturer creates a prohibitively large list, we list all supported manufacturers in a separate table with core part numbers arranged by technology family and pin count where applicable.

Well, apparently they are not big enough.
