MSP430AFE221: MSP430AFE221

Part Number: MSP430AFE221
Other Parts Discussed in Thread: MSP430FR2000

Hi, I am looking for some information and advice on how to go about selecting a 1-wire component. It would really help to get an overview of the components you offer.

I pasted in the part number as I know it is one of your 1-wire devices, but I am really looking for advice rather than technical detail of individual components.



  • Hey Isobel,

    Are you looking for Sensors or Microcontrollers that support 1 wire interfaces?  

    From an MCU standpoint, my understanding is that most MCUs can support 1 wire interfaces with some software.  Here is a app note showing an example on our low cost MSP430FR2000:  

    I'm not sure if we have a page showing available sensors or not if this is what you are looking for.   



  • Hi JD,

    Many thanks for getting back to me.

    We are conducting this search on behalf of a client, a multinational consumer goods company. They want a memory authentication system for their consumer device which has a consumable cartridge. They would be needing hundreds of millions of 1-wire microcontrollers per year.

    I am attaching our questionnaire for suppliers. Maybe you could take a look at either fill it in or we can talk through the questions?

    I wouldn't mind talking to a European or UK distributor if that would be easier for everyone.

    Thanks for your help.

    With best wishes,

  • Hey Isobel,

    I took a quick look, but I'm not sure what information you need.  Our biggest distributors in EU are Arrow and Avnet, so maybe you can reach out to them.
