EPROMs are easily recognizable by the transparent fused quartz window in the top of the package, through which the silicon chip is visible, and which permits exposure to ultraviolet light during erasing.

Archived PDF from the original on You will be notified when this product gets stocked. Glass is spotless, but that would only affect erasing. Since the whole memory array is exposed, all the memory is erased at the same time. ANY compiler will be handy.

I pretty much always erase my devices for minutes instead of the typical just to ensure this doesn’t happen. Presence of a voltage on this gate creates a conductive channel in the transistor, switching it on.

The first generation devices were fabricated with the p-MOS techology. While parts of the same size from different manufacturers are compatible in read mode, different manufacturers added different and sometimes multiple programming modes leading to subtle differences in epfom programming process.


27C512-200 – 27C512 512K 200ns CMOS EPROM

Storing data in the memory requires selecting a given address and applying a higher voltage to the transistors. Passes blank checks with no issues. Each bit of the word is a 1 or 0, depending on the storage transistor being switched on or off, conducting or non-conducting. I’ve had lots of problems with these “used good” 27C eproms that are typically found on eBay and even major suppliers. Shining ultraviolet light on any part of an unpackaged device causes a photocurrent to flow from the floating gate back to the silicon substrate, thereby discharging the gate to its 27f512, uncharged condition photoelectric effect.
