EPROM, what is EPROM
The EPROM (Erasable Programmable ROM) chip can be repeatedly erased and written, which solves the drawback that the PROM chip can only be written once. The EPROM chip has a very obvious feature. On the ceramic package on the front side, a glass window is opened through which the integrated circuit can be seen. The ultraviolet light can be erased through the hole to illuminate the internal chip. The internal data, the EPROM eraser is used to complete the chip erase operation. The writing of the data in the EPROM requires a dedicated programmer, and a certain programming voltage must be added when writing content to the chip (VPP=12-24V, depending on the chip model). The EPROM model starts with 27, such as 27C020 (8*256K) is a 2M Bits capacity EPROM chip. After writing the data, the EPROM chip also seals the window with an opaque sticker or tape to protect the data from the surrounding ultraviolet rays.
