M48T201Y, M48T201V Maximum ratings
27/37
4 Maximum ratings
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.
Table 10. Absolute maximum ratings
Caution: Negative undershoots below –0.3 V are not allowed on any pin while in the battery backup
mode.
Caution: Do NOT wave solder SOIC to avoid damaging SNAPHAT sockets.

1. For SOH44 package, standard (SnPb) lead finish: reflow at peak temperature of 225°C (the time above
220°C must not exceed 20 seconds).
2. For SOH44 package, lead-free (Pb-free) lead finish: Reflow at peak temperature of 260°C (the time above
255°C must not exceed 30 seconds).
