For a UV erasable versions, the user can use an EPROM Eraser to erase data before reprogramming. For an OTP version, the memory in each address cannot be programmed one time. Edit the buffer or load file to the bufferĮRPOM devices usually have a one-time programmable (OTP) and a UV erasable version.
Erase the chip by filling the buffer with all "FF", then running Program and Verify.Enable Insertion Test under operation option of the software to verify if setup is correct prior to performing any chip operation.Insert the socket adapter at the bottom of the 48pin DIP socket with the adapter part number on the top.Run Erase, Blank_Check, Program, Verify.įor some EEPROM devices that don't have Erase function in the software, the user needs to erase the chip by filling the buffer with all "FF", then running Program and Verify.Enable Insertion Test (and ID check) under operation option of the software to verify if setup is correct prior to performing any chip operation.
Insert the chip into the socket by following the position of pin 1 according to the instructions in the adapter information box.Insert the socket adapter at the bottom of the 48pin DIP socket with the adapter part number on the top.Test Procedure I to test your own EEPROM. Users can edit Auto in the function screen or program chips by selecting different functions manually.įigure 1 shows a screenshot of programming an EEPROM MX28F1000P. Each device also has a basic Auto operation, which will automatically execute chosen operations in sequence. Xeltek programmer software includes Chip_Erase, Blank_Check, Program, Verify and Read functions. Programming EPROM/EEPROM using Xeltek SuperPro programmers After erasing by exposing under strong ultraviolet light, the user can program the UV EPROM again. The UV version EPROM is a reprogrammable device. Once programmed, the user can only reprogram the area which was not programmed before. 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.
