DC Input Voltage -0.5V to VCC + 0.5V
Max. Output Current into any Pin 60mA
Power Dissipation 300mW
Static Discharge Voltage (USB and button inputs) >2000V
Latch-up Current >200mA
EEPROM write cycles (same byte) ≥1000

Mechanical Shock * 10,000g, ≤100μs
2,000g, ≤1ms
Free fall onto hard surface * ≤1.5m
*) Maximum shock specs apply for the sensor element only. Using the module in high g environments
will require additional mechanical protection.
