MSP430C315

Other Parts Discussed in Thread: MSP430FR4133, MSP430FR4131

Hi, I have an old design with a MSP430C315 microcontroller which is obsolete. I need to update this to a more recent processor. I don't have a lot of experience with MSP processors.

Where do I have to pay attention to when selecting a newer MSP processor to make it work with the old software? What are the main differences? I can't find a comparrison chart between the 3 series and the 6 series, they have comparrison charts for the 2 and 4. 

  • Hi,

    Regardless of the microcontroller that you choose, you will need to make changes to the software, because somethings will always be different, such as register names, etc. So I recommend that you chose a new device based on the peripherals, memory, operating frequency, and other relevant factors. If you tell me what peripherals/modules you are using and what your constraints are I can help point you to the right device.

  • Hi Nathan,

    The peripherals I need are:

    - LCD controller

    - Precision comparator with timer interrupt

    - Clock freq. 1 Mhz

    It also would be great if it's pin compatible with the MSP430C315IDL SSOP-56 package.

    Also I need more power modes, but I think this is a general feature of the MSP430 which all have nowadays. 

  • Hi,

    Based on those peripherals, I would suggest that you look at the MSP430FR4133 (or MSP430FR4131 or MSP430FR41312 depending on how much memory you need). I do not believe you will find a device that is completely pin compatible, so you will probably need to update your design. The code will also require some changes, but it should be fairly similar.

  • Hi Nathan,

    Those devices don't have a comparator. I need a comparator which is connected to a timer for an external AD-Slope conversion

  • Hi,

    I apologize for the oversight. Please see the following link for a searchable list of MSP430 devices. I have added both LCD controller and comparator to the desired features, so you can see the list to pick your part based on price, memory and package shape and size.
