Device failure is defined as: “If after exposure to ESD pulses, the device does not meet the device specification
requirements, which includes the complete DC parametric and functional testing at room temperature and hot
temperature.”
During start up operation the minimum required voltage to come out of reset state is 4.6 V.
An internal regulator controller can be used to regulate core supply.
The minimum supply required for the part to exit reset and enter in normal run mode is 1.28 V.
An internal regulator can be used to regulate 3.3 V supply.
