texas instruments TMS27C128 131 072-BIT UV ERASABLE PROGRAMMABLE READ-ONLY MEMORY TMS27PC128 131 072-BIT PROGRAMMABLE READ-ONLY MEMORY handbook
This datasheet describes the TMS27C128 series of 131,072-bit ultraviolet-light erasable, electrically programmable read-only memories (EPROMs) and the TMS27PC128 series of one-time electrically programmable read-only memories (PROMs). Both devices utilize power-saving CMOS technology and are pin-compatible with existing 128K MOS ROMs, PROMs, and EPROMs.

Questions answered in these manuals
What is the difference between the TMS27C128 and TMS27PC128?
The TMS27C128 is UV erasable, while the TMS27PC128 is one-time programmable.
What voltage is required for programming?
Programming requires a 12-13 V supply (Vpp) in addition to the 5-V supply.
How is the TMS27C128 erased?
It is erased by exposing the chip through a transparent lid to high intensity ultraviolet light.
