powered up. After Core VDD and NVDDx are stable, the analog supplies can be powered up.
3.2.2
There are no special requirements for the power-down sequence. All power supplies can be shut down at
the same time.
3.2.3
In order to guarantee DryIce power-loss protection, which includes that SRTC time is kept during
power-down; in addition to having the proper capacitor placed on the NVCC_DRYICE output pin, users
must follow the specific power-up/down sequence.
For users who want to utilize the DryIce power-loss protection feature, the following power-up sequence
is recommended:
Freescale Semiconductor
QVDD and NVDD
Analog Supplies
1. Assert Power on reset (POR).
2. Turn on NVCC_CRM.
3. At any time from step 2 and to step 4, turn on other digital I/O power suppliers NVCCx.
4. Turn on digital logic domain QVDD no less than 1 ms and no greater than 32 ms after
NVCC_CRM reaches 90 % of 3.3 V. Step 2 and step 4 order are critical for proper power-loss
protection.
shows the power-up sequence diagram. After POR_B is asserted, Core VDD and NVDDx can be
POR_B
Power-Down Sequence
SRTC DryIce Power-Up/Down Sequence
This is to guarantee that POR is stable already at NVCC_CRM/QVDD
power domain interface before QVDD is on, and POR instantly propagates
to QVDD domain after QVDD is on.
