Hi, I am a student of computer science. I am new in embedded world. I have some MAC7121 microcontroller. Can write the flash memory of that microcontroller through parallel port of pc(Using some external circuit). If I can then please explain the way & give necessary links. Also give info about external circuit if it is necessary. If I can't is any 32 bit microcontroller exists in whose flash memory/EEPROM I can write through parallel port. Please infom. THANKS, NASIF

The Mac7121 is 2.5V and parallel port is 5V logic. Straight connect will surely burn out the chip.
