7. People also ask

   How do I change a 0 to a 1 in m27c512?

   • The only way to change a '0' to a '1' is by die exposure to ultraviolet light (UV EPROM). The M27C512 is in the programming mode when VPP input is at 12.75V and E is pulsed to VIL. The data to be programmed is applied to 8 bits in parallel to the data output pins. The levels required for the address and data inputs are TTL.

   What are the erasure characteristics of the m27c512?

   • The erasure characteristics of the M27C512 is such that erasure begins when the cells are exposed to light with wavelengths shorter than approximately 4000 Å. It should be noted that sunlight and some type of fluorescent lamps have wavelengths in the 3000-4000 Å range.
