Hello,

I would like to know why some pic chip do not come with EEprom ?
I guess external memroy is needed to operate the chip?
Isn't the program we write go into the EEprom ??

I would like to know why some pic chip do not come with EEprom ?

For the same reason that some comes with USART, somes not, some with ADCs, somes not...

NOPE, if so it's not called a PIC.



Isn't the program we write go into the EEprom ??


NOPE, EEPROM is just an extra storage place... nothing to do with the ProgramMemory OR RAMmemory.

kind of, PC with/Without 2nd hard drive, 3 1/2 Floppy disk, FlashCard reader and so ON.
