7.1 Absolute Maximum Ratings(1)

over operating free-air temperature range (unless otherwise noted)
MIN MAX UNIT
Supply Voltage Range VDD Steady-state supply voltage –0.3 1.4 V
VDD33 Steady-state supply voltage –0.3 3.8 V
Voltage Range USB_SSRXP_UP, USB_SSRXN_UP, USB_SSRXP_DN[4:1], USB_SSRXN_DP[4:1] and USB_VBUS terminals -0.3 1.4 V
XI terminals -0.3 2.45 V
All other terminals -0.3 3.8 V
Storage temperature, Tstg –65 150 °C
(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

7.2 ESD Ratings

VALUE UNIT
V(ESD) Electrostatic discharge Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V
Charged device model (CDM), per JEDEC specification JESD22-C101(2) ±500
(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.

7.3 Recommended Operating Conditions

7.6 Timing Requirements, Power-Up

PARAMETER DESCRIPTION MIN TYP MAX UNIT
td1 VDD33 stable before VDD stable(3) See (2) ms
td2 VDD and VDD33 stable before de-assertion of GRSTz 3 ms
tsu_io Setup for MISC inputs(1) sampled at the de-assertion of GRSTz 0.1 µs
thd_io Hold for MISC inputs(1) sampled at the de-assertion of GRSTz 0.1 µs
tVDD33_RAMP VDD33 supply ramp requirements 0.2 100 ms
tVDD_RAMP VDD supply ramp requirements 0.2 100 ms
(1) MISC pins sampled at de-assertion of GRSTz: BATEN[4:1], AUTOENz, FULLPWRMGMTz, GANGED, SMBUSz, and PWRCTL_POL.
(2) There is no power-on relationship between VDD33 and VDD unless GRSTz is only connected to a capacitor to GND. Then VDD must be stable minimum of 10 µs before the VDD33.
(3) An active reset is required if the VDD33 supply is stable before the VDD11 supply. This active Reset shall meet the 3ms power-up delay counting from both power supplies being stable to the de-assertion of GRSTz.
