hello fonak can u provide .hex file for programmer
Hello, unfortunately not. The chip is likely protected by fuses.
A pre-programmed PIC16LF1454 chip can be purchased from the manufacturer's website:
https://www.northernsoftware.com/buy/buy.cgi , and is quite inexpensive ($5).
Based on the manufacturer's information, you can easily build a universal programmer.
For example, you can buy the 5V version of the PIC16F1454 and add a GTL2003 buffer with the appropriate 5V<->3.3V power switch.
