I have to apologize because I have found the answer just a micocontroller posts below after posting this. One option is to use a 1-wire “silicon serial number” chip DS Each is guaranteed to have a unique bit serial number, and you only need to use up one pin of the MCU to interface with it.

Microcontrollers unique ID ?

Another way is to have your flash programmer insert a unique serial number at a fixed location in each image it saves, but if you’re doing remote updates that might wipe out the number unless you’re careful to not reprogram that flash block.


To read a string of bytes from a pre-determined memory address FFFC0 in this exampleuse code like this:.

The solution with external chips is to complicated i think. I would prefer to save a ID in program memory. Another issue is that: FDT does not support such an old device as M This is provided as Visual Studio 6 micocontroller on the Renesas hompeage http: Do I need a bootloader?

I also have some information on serially programming m32c’s here: If your application provides a UART interface on UART1 of the device, and if the application has some jumper or so to set the device to flash programming you don’t need additional hardware for programming M User Join or Sign In.

In order to identify a device I would like to read out a uniqie ID from the mfcgp. Do I have to write a ID in memory first or does such a number already exist?

Anyway, if there is no such serial number how could I create one? The simliest way would be to save a variable in every MCU i think. The variable should be in a non volatile part of memory. How can I achieve m116c


Are there any specifiers like: To read a string of bytes from a pre-determined memory address FFFC0 in this exampleuse code like this: Thank You both for these suggestions. I still have some questions: Ok, now its clear.

I already downloaded FDT. Just a few things have to be taken care of, like connecting some pins of the MCU properly. Schould I choose the generic boot device? What if I use: All M16C devices have a boot loader built-in.
