Hello All, I am a newbie and have some basic questions Re ROMless microcontrollers (E.g.PIC18C601 ) What is the purpose of ROMless microcontrollers? Do they increase performance? Where is the program code written as this type doesnt have Flash or ROM ? 1 reason tht came to my mind was, may be the in built ROM of microcontroller is insufficient and with ROMless a user can access to external memory ,application dependent and a Bootloader than does rest of job, but again for bootloader we need a ROM, at this point a bit confused. I would appreciate any explaination or links.,Thanks !! googling didnt help much :( Abhi -- View this message in context: http://www.nabble.com/Re-%27ROMless-microcontrollers-tp18848800p18848800.html Sent from the PIC - [PIC] mailing list archive at Nabble.com. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
