1.
Valid for ambient operating temperature: TA = –40 to 85°C; VCC = VLV to VHV (except where noted). All physical and
environmental tamper functions are operational across the full temperature alarm range for STM1404.
2.
In the case of STM1404A, physical tamper input pins (TPX) are referenced to VOUT (pin 12). In the case of STM1404B or
C, TPX are referenced to VTPU pin (pin 9).

VCC = VRST (max) to 3.6 V
