any 1 have the schematic diagram of microcontroller...for mon51
i wan to ask that...even the microcontroller have internal ram/rom, it also require external ram/rom ? it must hav: 1 external ram (store program) 1 eeprom (for mon51 program) 1 microcontroller 1 latch max232 and rs232 ...?
If you only have RAM how will you get the monitor program into the RAM chip so you can run it?
we cant save the monitor program in ram too ? same with the program code, both save in ram? can it work ?
How are you going to get it in to RAM? The CPU can not do it without running code. Or are you going to build some external device to put the program into the RAM. Or is the Program going to be in a chip with Flash program memory?
