SAMSUNG KM2864A-25 EEPROM 8kx8-bit 250 ns. 28 pin plastic DIP.
New old stock from opened boxes. Untested, but money back or replaced if it isn't working.
See my other auctions for the -AH variant with faster write cycle.
I use ESD bags and equipment while shipping and handling the components to reduce the risk of damage a working component.
Shipping is by letter. If you want tracking and insurance I can send it as registered letter but it will add $10 to the shipping cost. Just ask for a new invoice in that case.
I only charge what it cost in shipping and I combine shipping whenever possible. If you have any questions on the postage for more than one auction, just ask.
Any further questions, just ask.
