Hi champs,

for minimum configuration (BOM) as CapTIvate controller, is external 32.768KHz crystal XT1 needed ?

What are applications, where XT1 is needed ?

    Hi DJ-NG,

    An external 32 kHz XT1 is not required for CapTIvate technology. The greatest benefit is ultra-low power optimization but the internal REFO or VLO can be used instead to achieve LPM3/4. The drawback is that the accuracy of either will be slightly degraded as compared to the crystal option and REFO will draw slightly more current. More information is provided in the Design Guide/Ultra Low Power section of the CapTIvate Technology Guide.

    Regards,
    Ryan
