about MSP430 family microcontrollers..

Hi...

I am doing a project "hearing aid",in which audio signals, from 40hz to 8khz need to be sampled,any frequency band within frequency range can be selected.we need a suitable MSP430xxx family microcontroler to implement  the filters with ADC which can convert audio signal frequencies upto 8kHz..

    All MSPs are able to sample on 8kHz. (200kHz and more are no problem on MSPs with the ADC12 module)
    However, it depends on your programming skills and the project requirements whether you can process this amount in realtime on the MSP.

    On 25MHz system clock, you have ~3000 MCLK cycles per sample. Depending on what you want to do and how you do it, this might be way more than you need or by far not enough.

    Because of the memory requirements and the 32bit hardware multiplier, I suggest a member of the 5x family. E.g. the 5418A
