Hi all ,
I am having critical issue about the supported voltage PIC18f4550 .
1) Are there two pic18f4550 microcontrollers which are having two INPUT voltages as 3v and 5 v or is it two operation modes in the same microcontroller?
2) If there are two microcontrollers in the above mentioned chip, will it be any significance affect to the program what we are feeding to it? ( I mean in configuration wise)
i am asking this because i got to kind of thing from my friend... What he said is there are two products for each microcontroller as high power thing and low power thing...
But i read the data sheet of pic18f4550 but it says only,
• Single-Supply 5V In-Circuit Serial
Programming™ (ICSP™) via two pins
• In-Circuit Debug (ICD) via two pins
• Optional dedicated ICD/ICSP port (44-pin devices only)
• Wide operating voltage range (2.0V to 5.5V)
clarify this small issue as soon as posible...
thnx a lot for ur coments in advance
