Supply Power-Up Requirements and Restrictions
Any i.MX31/i.MX31L board design must comply with the power-up sequence guideline, as described in
this section, to guarantee proper power-up of the device. Any deviation from this sequence may result in
any or all of the following situations:
Cause excessive current.
Prevent the device from booting.
Cause irreversible damage to the i.MX31/i.MX31L (worst-case scenario).
The Power On Reset (POR) pin must be kept asserted (low) throughout the power up sequence. Power up
logic must guarantee that all power sources must be on prior to the release (de-assertion) of POR.
Figure 2
depicts the power supply power up sequence. (Power management logic should guarantee 90% supply
before transitional to the next state.) The sequence is as follows:
1. Quiet supplies—QVCC, QVCC1, QVCC4 (peripherals, ARM, L2 cache)
2. NVCC1 and IOQVDD—for assuring reset signals are propagating into core
WAIT (all clocks
gated off)
All Vdds = 1.2 V (QVCC=QVCC1=QVCC4 = 1.2 V)
