That glass window on the chip is how it's erased (by putting it under UV light for a half hour or so). Normally that's covered-up after it's programmed, and a part number label is commonly used to do that.
It looks like there's some old label glue on the chip, like the original label may have been removed (or may have just dried-up and fallen off). That missing label probably had the info you want, and it's probably no more than an electronic hobbyist's curiosity without that info. |
