Special Signal Considerations
Special signal considerations are listed in Table 5. The package contact assignment is found in Section 4,
“Package Information and Contact Assignments.” Signal descriptions are provided in the reference
manual.

Descriptions
PSWITCH
The pin is used for chip power on or recovery. VDDIO can be applied to PSWITCH through a
10 k
Ω resistor. This is necessary in order to enter the chip’s firmware recovery. The on-chip
circuitry prevents the actual voltage on the pin from exceeding acceptable levels.
VDDXTAL
This pin is an output of i.MX28. Should be coupled to ground with a 0.1 uF capacitor. User
should not supply external power to this pin.
BATTERY
This pin should be connected to the battery with minimal resistance. It provides charging current
to the battery.
See the “Power Supply” section of the reference manual for details.
DCDC_BATTERY
This pin is an input of i.MX28 that provides supply to the DCDC converter. It should be
connected to the battery with minimal resistance. See the “Power Supply” section of the
reference manual for details.
XTALI
XTALO
These analog pins are connected to an external 24 MHz crystal circuit. This crystal provides the
clock source for on-chip PLLs.
RTC_XTALO
RTC_XTALI
These analog pins are connected to an external 32.768/32.0 kHz crystal circuit. This crystal
provides clock source to the on-chip real-time counter circuits.
RESETN
This pin resets the chip if it is low. This pin is pulled up to VDDIO33 with an internal 10 kohm
resistor. No external pull up resistors are needed.
DEBUG
This pin is used for JTAG interface.
DEBUG=0: JTAG interface works for boundary scan.
DEBUG=1: JTAG interface works for ARM debugging.
TESTMODE
For Freescale factory use only. Must be externally connected to GND for normal operation.
