If you already own the eraser, it’s more economical to use the old stuff sometimes. Only one chip was completely erased, most had one to six errors, each error byte had all zeros in it.

However, this chip is no longer listed on their website, so dtaasheet probably out of production.

A core part number 232 a number which identifies a device regardless of the manufacturer. So, six to ten hours under UV. There is a pattern on each chip, meaning that a certain bit across the chip will program and certain other bits will not. The non-epoxied ones have a gold square holder for the quartz window and that is soldered to the package. If so, if there a datasheet, or any other information on it.


Nevermind, I found the AT28C64 datasheet. I’ve forgotten my password. Their high storage capacity allows use in computer BIOS plus other memory intensive product applications.

The eeprom chip, along with the ce, oe and we pins, will also have a set of pins for setting an address and a set of pins for readingwriting data to the selected address. It just repairs the insulation on the floating gates. I purchased 15 of these chips at a bargain price, which wasn’t much of a bargain. It’s 30 years old and I wonder if it is still good.

I’ll get a new 273.

These memory chips store the bits of data by blowing small fuses inside datwsheet memory device. A microcontroller normally has 40 or more pins since the input and output operations occur directly from the chip.

My A machine has 64K of memory. I thought that maybe if I cycled the chips maybe it would help, but no soap. It could be used with 4k games on an 8k board by doubling up the ROM first.

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. The 6n89 and hcplhcpl octocouplers dataseet of an algaas led optically coupled to a high gain split darlington photodetector. These parts are always in plastic cases because the erasing of the part is done electrically without the need to expose the internal chip to ultraviolet light. Mike Baking was something we did in the lab when I worked for Intel.


It worked like a champ. They are all the same. Been reading around, looks like the 28c16 eeprom is said to be pin compatible with eproms. Javascript Disabled Detected You currently have javascript disabled. I don’t think my programmer is the problem. I don’t know much about them.

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. Posted Sat Jul 4, 1: Hall sensor amplifier buffer compensation bias unit eeprom unit. Well, apparently they are not big enough. I figure the only thing I have to add to my memory card is a switch to either connect the MEMW to the chip or to ground it so that it is protected daatasheet when I screw up and send the machine off into the pucker brush.

Remember, a eeprom part number usually represents hundreds of actual dafasheet numbers due to different manufacturers, speeds, temperatures, package types and other chip characteristics. Ma datasheet, ma datasheets, ma pdf, ma circuit.

I picked up 15 eproms on ebay. The data pattern of each was all the same octal in all cells.

2732-compatible EEPROM?

There are plenty of alternatives. Wired it in and programmed it. Please re-enable javascript to access full functionality.
