EEPROM, slightly O.T.

Got away without needing a pulse. Do they require an exact timing pulse to be applied to the “not WE” pin, in order to write to it? I have one of those, it works great. You won’t get dataasheet without a data sheet for exactly the parts you have, and even then it’s a lot of work to make a programmer that does the job correctly. Reason Report to Moderators I think this message isn’t appropriate for our Group. Been there and successfully done both.

What am I missing here? Hello, Forgive this slightly off-topic question: One day A good customer came in the shop all upset that his drive was dead, I hald datazheet to my nose and went to the back to get datashee screwdriver and a chip.

Again, read the data sheet carefully and make sure it’s for the exact same device and manufacturer. Anyone familiar with these parts? The Group moderators are responsible for maintaining their community and can address these issues. However, if you are looking to program EEPROMs, you may get good ideas from the Willem programmer, as it seems to be open-source of some variety.

To go even more off-topic Some as low a 10, They are not intended to hold actual program code, even though you could do this.

It’s easy to find info on the 28C A ZIF socket was inserted in one of those slots. Most sane people don’t spend their time building clocks with antiquated technology!

Sometimes 2 extra supplies. The new topic will begin with this message. Both of them require interesting programming voltages and very fussy timing sequences to work. If the user put the cable on wrong, the 74LS would turn into a 74LS mount st helens. Writing was a bit different. Chuck Richards Chuck, The is an electrically-erasable version of the First hit on google: A RAM device, obviously, can be written to, about the same speed as it can be read. Subject of the new topic: At 10mS per byte, it would get quite tiresome.

Their site has forums that may point you in the right direction. I’ve never used the Willem Programmer, I don’t sell it, etc.

Once I fixed that it has been great, and the blame goes to the Korean manufacture of my particular unit rather than the design itself. It depended on manufacturer.

Two E’s instead of one Big difference. Thanks anyway for your valuable time. Egg on my face.

Back in the late ‘s I had an S based programmer that did ‘s and ‘s. I think it’s an open-source homebrew programmer — you can build it yourself or buy it already built.

These requirements are different for different manufacturers and even different part numbers from the same manufacturer. Most new ones withwrite cycles, before data transfers get iffy.

What do I need to do, in order to write data to the or 28C16? No contracts, No fees, No Kidding!
