The OTP version EPROM can be programmed once and it can't be erased electrically. EPROM devices have two versions: OTP (One-Time Programmable) and UV version.
An EPROM can also retain its data when its power supply is switched off. Furthermore, the data stored in an EEPROM chip is not lost even when the power is turned off. Data stored in an EEPROM chip is permanent, unless the user decides to erase and replace the information it contains. EEPROM, unlike EPROM, can be written in or programmed more than once. Xeltek SuperPro universal programmers support a variety of EPROM / EEPROM chips from different manufacturers.ĮEPROM stands for Electrically Erasable Programmable Read-Only Memory, and EPROM stands for Erasable Programmable Read-Only Memory.
