Maximum rating
Stressing the device above the rating listed in the “absolute maximum ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
program and other relevant quality documents.

budget not to exceed 180°C for between 90 to 150 seconds). No direct exposure to infrared (IR) reflow, or
IR preheat allowed, to avoid damaging the embedded 32KHz crystal.
