Although you will stumble over programmers for EEPROMs, matching eraser units are few and far between. The small ‘hed.eraser’ solves the problem quickly and efficiently.Even after more than ten years, various Flash technologies have failed to completely supplant EPROMs. This is surprising because erasing an EPROM using a dose of UV light is tedious, while the glass window in the housing of EPROMs adds considerably to the device manufacturing cost. The Electrically erasable EPROM (EEPROM) is an attractive alternative. Just like the EPROM, it can be ‘burned’ in traditional programmer systems. Moreover, it is 100% electrically compatible with UV erasable counterparts. However, not all programming systems for EPROMs are capable of actually erasing an EEPROM, and that is why such a tool is presented in this article.
