The Attiny13 is a 1k 8-bit AVR chip (Atmel), the 12F617 is a 3.5k 8-bit PIC chip (microchip). You can use the same clip since they’re both available in SOIC8 package but everything is different, the programming hardware, the software / programs to write the code / program the chips, the code, the pinout.
tterev3’s who got me to start PIC, now all my new projects are PIC based.
