I got an EPROM without a window? Answered
I got the AT27C040 that is a 4-Mbit "EPROM" without a window.
After reading the datasheet, I was wondering:
- Why an Erasable PROM would not be housed in a package with a window?
- Is there any way I can erase it other than drilling a hole in it?
- (I've heard that you can 'refresh' the EPROM to get the same result as UV)
- Should I Just return the thing if there is a way to do so?
