MSP430FR2633: TIDM-1021 performances at -40°C

Part Number: MSP430FR2633
Other Parts Discussed in Thread: TIDM-1021

Dear e2e support,

Could you confirm if our TIDM-1021 or similar ref design could work at -40°C (intended for a rugged outdoor application)?

Are there anything we should take care of, specifically (calibration, etc....)?

Regards,

    Hi TISL,

    The MSP430 device will operate down to that temperature as specified in the datasheet.  The Captivate software algorithm automatically tracks changes in sensor capacitance performs a periodic re-calibration as needed.  Therefore, the device can operate and maintain calibration across the operating temperature of the device.

    Hi Dennis,

    Many thanks for your feedback.

    We've also seen that a keypad application with our CapTIvate can work with different kind of gloves (video here).

    Did we ever test it with winter gloves at -40°C? meaning relative high distance, at low temperature

    Regards,
