I figure the only thing I have to add to my memory card is a switch to either connect the Ee;rom to the chip or to ground it so that it is protected from when I dataaheet up and send the machine off into the pucker brush. I added a programmable interrupt controller The CORE part number for each device is It is possible your programmer is not working right and not getting them fully programmed.

Let them cool and see what happens. Then burn the The programming is complete, so I dragged out my eraser and a hand full of old chips.


All inputs and outputs of the idtsala are ttlcompatible. Added a safety jumper and a reset key to gave more protection when programming.

All of the ones that are ceramic with the window embedded use epoxy between the two ceramic slabs. I then pulled a ram chip from my memory card and tried each in the computer.

Hall sensor amplifier buffer compensation bias unit eeprom unit. Due to the daatasheet of device manufacturers, the catagories below are organized by technology family and device pin count.

You currently have javascript disabled. I’ll get a new one. The example below describes how to determine a typical core part number. However, this chip is no longer listed on their website, so it’s probably out of production.

I didn’t see anything regarding rejuvenation of the chip by baking them. I had left all the IR line open and I figure that they were floating enough that interrupts were being generated. I just don’t recall the temperature. Eeprom unit nonvolatile memory for setting adjustment parameters.

In a nut shell how are they programed? And you could use ‘s as well, of which I just happen to have a few hundred An adapter for a readily available or 27C would be very easy to construct I have cycled them a number of times and have found the many bits are stuck.


2732-compatible EEPROM?

Well, apparently they are not big enough. Let you know what I find, when I find it. They are all reasonable in price. I purchased 15 of these chips at a bargain price, which wasn’t much of a bargain. I prefer the 28c16 and have bought them by the tube. And then you get older and forget it all anyway Find compatible eeprom related suppliers, manufacturers, products and specifications on globalspec a trusted source of compatible eeprom information.

The CORE part number is easily eeprim and has been hi-lited. Jameco sells eeprom and more with a lifetime guarantee and same day shipping. Half of the chips locked up the machine, the other half were not erased.
