Presence of a voltage on eprmo gate creates a conductive channel in the transistor, switching it on. Leaving the die of such a chip exposed to light can also change behavior in unexpected ways when moving from a windowed part used for development to a non-windowed part for production.

To erase the data stored in the array of transistors, ultraviolet light is directed onto the die. Is there a feature that let you program slower? Visit eBay’s page on international trade. Are you sure you erase long enough? Have one to sell?


Select a valid country. To retrieve data from the EPROM, the address represented by the values at the address pins of the EPROM is decoded and used to connect one word usually an 8-bit byte of storage to the output buffer amplifiers.

There are 50 items available. Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. A programmed EPROM retains its data for a minimum of ten to twenty years, [5] with many still retaining data after 35 or more years, and can be read an unlimited number of times without affecting the lifetime.

This prompted larger capacity devices to introduce a “signature mode”, allowing the manufacturer and device to be identified by the EPROM programmer. In other words, to erase your EPROM, you would first have to X-ray it and then put it in an oven at about degrees Celsius to anneal semiconductor alterations caused by the X-rays.

EPROM 27C512 – Blank or with specified programming

Also, this thread may be eprkm Here are the issues I need to solve please correct me if i am mistaken: It was soon found that small-volume production was economical with EPROM parts, particularly when the advantage of rapid upgrades of firmware was considered. An insulating layer of oxide is grown over the channel, then a conductive silicon or aluminum gate electrode is deposited, and a further thick layer of oxide is deposited over the gate electrode.

Glass is spotless, but that would only affect erasing.
