Operating temperature range -40°C to 85°C (TA) covers industrial and commercial environments — the supervisor's own drift across this band determines whether the threshold stays within the processor's reset window at the cold end. ## SOT-143-4 package — footprint and board integration Housed in a SOT-143-4 (TO-253-4) surface-mount package, the four-pin footprint matches the standard supervisor layout used across the STM812/STM810 family — the same PCB land pattern accepts the pin-compatible STM813LM6F without a board spin.","metaTitle":"STM812LW16F Simple Reset/Power-On Reset, 4.63V Threshold","metaDescription":"STMicroelectronics STM812LW16F supervisor IC, Active High reset, 4.63V threshold, 140ms timeout, SOT-143-4.

Both share the same SOT-143-4 package, Active High push-pull output, 140 ms timeout, and single-voltage monitoring.
