Electrical characteristics

Freescale Semiconductor

WARNING

Incorrect voltage select settings can lead to irreversible device damage. See Section 3.2,

“Supply power default setting.”

NOTE

From a system standpoint, if any of the I/O power supplies ramp prior to the VDD_CA, or

VDD_PL supplies, the I/Os associated with that I/O supply may drive a logic one or zero

during power-up, and extra current may be drawn by the device.

2.3

Power-down requirements

The power-down cycle must complete such that power supply values are below 0.4 V before a new power-up cycle can be

started.

If performing secure boot fuse programming per Section 2.2, “Power-up sequencing,” it is required that POVDD = GND before

the system is power cycled (PORESET assertion) or powered down (VDD_PL ramp down) per the required timing specified in

Table 5.

VDD_PL and USB_VDD_1P0 must be ramped down simultaneously. USB_VDD_1P8_DECAP should starts ramping down only

after USB_VDD_3P3 is below 1.65 V.

2.4

Power characteristics

This table shows the power dissipations of the VDD_CA, SVDD, and VDD_PL supply for various operating platform clock

frequencies versus the core and DDR clock frequencies for the chip.
