Recommended operating conditions

The operating conditions are the physical parameters that the chip can operate within.

Table 1. Recommended operating conditions
Symbol Parameter Notes Min. Nom. Max. Units
VDD Supply voltage, independent of DCDC enable 1.7 3.0 3.6 V
tR_VDD Supply rise time (0 V to 1.7 V)   60 ms
TA Operating temperature -40 25 85 °C
Important: The on-chip power-on reset circuitry may not function properly for rise times longer than the specified maximum.

WLCSP light sensitivity

All WLCSP package variants are sensitive to visible and close-range infrared light. This means that a final product design must shield the chip properly, either by final product encapsulation or by shielding/coating of the WLCSP device.
