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