Electrical Characteristics

Freescale Semiconductor

4.2.1

Power-Up Sequence

Figure 2 shows the power-up sequence.

Figure 2. Power-Up Sequence

NOTE

1) The POR_B input must be immediately asserted at power-up and remain

asserted until after the last power rail is at its working voltage.

2) No power-up sequence dependencies exist between the supplies shown

shaded in gray.

4.2.2

Power-Down Sequence

The power-down sequence is recommended to be the opposite of the power-up sequence. In other words,

the same power supply constraints exist while powering off as while powering on.

4.2.3

Resume Sequence

When the i.MX50 is resuming from STOP mode, there are some special sequencing considerations. The

resume timing is determined by the following internal counters:

1. STBY_COUNT. This register is in the CCM block and may be set to a maximum of 16 x 32 kHz

cycles, or 500

μsec.
