5.7 Power-Up Timing Requirements
| MIN | NOM | MAX | UNIT | ||
|---|---|---|---|---|---|
| td1 | VDD33 stable before VDD stable(1) | see (2) | ms | ||
| td2 | VDD and VDD33 stable before deassertion of GRSTz | 3 | ms | ||
| tsu_io | Setup for MISC inputs(3) sampled at the deassertion of GRSTz | 0.1 | μs | ||
| thd_io | Hold for MISC inputs(3) sampled at the deassertion 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) 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 deassertion of GRSTz.
(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) MISC pins sampled at deassertion of GRSTz: FULLPWRMGMTz, GANGED, PWRCTL_POL, SMBUSz, BATEN[4:1], and AUTOENz.
