Description
Analog for the SoC core logic.
Analog for the 3.3-V logic.
Generic Analog signal.
Reference voltage for the DDR SDRAM interface.
I/O power supply for peripherals I/Os.
I/O power supply for the memory DDR SDRAM I/Os. These I/Os are 3.3-V capable for Automated Test
Equipment (ATE), not for functional mode.
SoC core power supply.
Common ground for I/Os.
Common ground for the SoC core.
2.3 Signal Pin List
The following
pull-down or none (column ‘P’).
Remark: The pull-down in the BPT3MCHDT5V pads is NOT strong enough to
actually pull down a 5-V TTL input. Instead the TTL input pin sees a ‘1’.
Speciality pads, e.g. power supply, are described in the following table.
The following table details the interface of PNX1700. For pad and I/O types, refer to
the tables presented in
dedicated GPIO pin is always of I/O/D type). The ‘P’ column indicates if the signal is
pulled down, ‘D’, or pulled up, ‘P’ or neither ‘-’. Active low signals are suffixed by ‘_N’.

PCI_FRAME_N, PCI_TDRY_N, PCI_IRDY_N, PCI_DEVSEL_N, PCI_STOP_N,
PCI_SERR_N, PCI_PERR_N and PCI_INTA_N require an external pull-up. Refer
to Section 4.3.3 of PCI 2.2 specification for more details.
Any I/O or I/OD signal of the XIO bus must be pulled-up if they are not used.
GPIO[11:8] must be pulled-up or down.
