Is the maximum memory size of a variable limit with MSP430 microprocessors?

I would like to know that what is the maximum memory size of a variable limited with MSP430 microprocessors?

Please refer to the data sheet of the MSP430 controller you are using. under the section "Memory organization" you will find the size of RAM available on that particular controller.

controllers like MSP430F201x have RAM size of only 128 bytes, here the maximum ram size that you can use is 128, and the maximum size of array would be much lesser than 128 as you other variables will get occupied in part of the same RAM.

by the way which MSP430 MCU are you using?

Dear Friends,

I use MSP430F2619.  If I need to use two or more 256-byte arrays, what should I do? Thank you.

Post the linker file of your project.

Dear Friends,

The memory size is not the problem for my design, so what makes the error in my program. Thank you.

Dear Friends,

Would you mind telling me how to check whether the memory overlap? Thank you.

It's your program - so you need to do some debugging to find out exactly where it's going wrong!
