MSP 430 for consumer electronics

Other Parts Discussed in Thread: MSP430G2553

Hi,

Can we use MSP 430 as User Interface for low ends consumer electronics such as say (Washing Machines) or Is it used for any such application in industry?

I read somewhere Renesas ICs being used for user interface in consumer electronics products for various manufacturers.

I am thinking of at developing such an application where MSP 430 device is the user interface i.e. connected to a LCD display (which shows remaning time for washing), Timer control for washing machine , On/Off, temperature selection control for washing machine. etc. The MSP430 is just the user interface where corresponding to each button it sends a command over UART to Main controller which might be some high end processor to start the motor, controlling various sensors etc sending back reading to display such as water level,or door open or temperature reading to be displayed.

I have experience only with MSP430G2553, if I can use MSP430 for this purpose then which IC would suffice my needs? Any suggestion experts.

Thanks

    Well, the MSP can be used for everything you can imagine, as long as you won't exceed its operating conditions.
    Medical applciaitons are scarce since most MSPs don't have approval for medical applications. But whereever non lif-critical applications are done, an MSP is as good as any other microcontroller.
    Doing the described user interface is definitely a job for the MSP. The bigger MSPs can even do the whole thing, including motor control.

    Depends on many things. The LCD output (if you jsut want to add plain glass LCD) limits the selection to 4x and 6x family. Non of them has built-in capacitive sensor support, so if you want touch keys, you'll need some external hardware (or go for a timer-based charge/discharge approach). 6x family has the advantage of internal REFO clock for a fairly precise timing. The rest depends on how many I/O lines or communication lines you need.
    The 6x family devices are usually large enough to hold more complex code. Up to 256k flash and 18k ram should fit any requirement you might have in a washing machine control.
