#600 - RE: How to erase 8K EPROM inside 87c52 |
I think the device 87C52 is an EPROM device (has a window on the chip). Therefore it is not possible to erase it using a programming unit. You should expose the device to an ultraviolet light using eprom erase unit and then just test it in the programming unit if the device is empty (has all bytes 0ffh). |
