4.3
This section provides power-up and power-down sequence guidelines for the i.MX35 processor.
4.3.1
The power-up sequence should be completed as follows:
16
Static
Note: Typical column: T
Power
Mode
1. Assert Power on Reset (POR).
2. Turn on digital logic domain and IO power supply: VDDn, NVCCx
3. Wait until VDDn and NVCCx power supplies are stable + 32 μs.
VDD1,2,3,4 = 1.1 V (min.)
ARM is in wait for interrupt mode.
MAX is halted
L2 cache is kept powered.
L2 cache control logic off.
AWB enabled.
MCU PLL is off.
PER PLL is off.
All clocks are gated off.
OSC 24MHz is on
OSC audio is off
RNGC internal osc is off
Supply Power-Up/Power-Down Requirements and Restrictions
Powering Up
Any i.MX35 board design must comply with the power-up and power-down
sequence guidelines as described in this section to guarantee reliable
operation of the device. Any deviation from these sequences can result in
irreversible damage to the i.MX35 processor (worst-case scenario).
Deviation from these sequences may also result in one or more of the
following:
•
