The Absolute Maximum Ratings for (TS1–VSS) apply after the device completes POR and should be observed after tBOOTREADY

(10 ms), following the application of the boot signal on TS1. Prior to completion of POR, TS1 should not exceed 5 V.

(1)

JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

(2)

JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
