PC6-TANGO • CompactPCI®PlusIO • Intel® Atom™ E39xx Processor (APL-I SoC)
Overview
The PC6-TANGO is a low power 4HP/3U
CompactPCI
®
PlusIO CPU board, equipped with
an Intel
®
Atom
™
E3900-series System-on-Chip
processor (Apollo Lake). The front panel is
provided with two Gigabit Ethernet jacks
(option M12-X), two USB 3.0 receptacles, two
DisplayPort connectors, and a Micro SD Card
slot.
The PC6-TANGO is equipped with 8GB directly
soldered DDR3L ECC RAM, and a CFast™ card
socket as on-board SSD mass storage solution.
Optionally available is an on-board 64GByte
e•MMC flash memory chip. Further more, low
profile SATA SSD mezzanine modules are
available as additional on-board mass storage
solution. The PC6-TANGO backplane connectors
comply with the CompactPCI
®
PlusIO
specification, suitable for system expansion with
classic CompactPCI
®
peripheral cards via J1, and
in addition a rear I/O module attached to J2, or
up to four CompactPCI
®
Serial cards accessed
on a hybrid backplane.

PC6-TANGO • CompactPCI®PlusIO • Intel® Atom™ E39xx Processor (APL-I SoC)
CompactPCI® PlusIO (PICMG 2.30) is a
standard for rear I/O across J2, specified by the
PICMG®. High speed signal lines (PCI Express®,
SATA, Gigabit Ethernet and USB) are passed
from the PC6-TANGO through the special UHM
connector to the backplane, for usage either on
a PlusIO rear I/O transition module, or
CompactPCI® Serial card slots.
CompactPCI® Serial (PICMG CPCIS.0) defines a
completely new card slot, based on PCI
Express®, SATA, Gigabit Ethernet and USB
serial data lines. On a hybrid backplane, both
card styles can reside, CompactPCI® and
CompactPCI® Serial, with the PC6-TANGO in
the middle as system slot controller for both
backplane segments.
The PC6-TANGO is provided with a set of local
expansion interface connectors, which can be
optionally used to attach a mezzanine side
board, for additional mass storage or front I/O.
The C48-M2 mezzanine module e.g. is
equipped with two M.2 SATA Solid State Drives
(SSD), and fits on the PC6-TANGO while
maintaining the 4HP front panel profile.

Front Panel I/O (8HP)
<Option 2 x M12 X-coded receptacles for Gigabit Ethernet (as replacement for RJ45)
CompactPCI® & CompactPCI® PlusIO Backplane Resources
<PICMG® CompactPCI® 2.0 CPU card & system slot controller for J1 based 32-bit CompactPCI® systems
<Support for up to seven CompactPCI® peripheral boards, 33/66MHz (PI7C9X112 PCIe to PCI bridge)
<PICMG® CompactPCI® 2.30 J2 UHM connector according to CompactPCI® PlusIO
<J2 can be used to enable CompactPCI® Serial peripheral card slots for hybrid systems with a split backplane
<J2 can be used alternatively for a rear I/O module e.g. PR1-RIO
<J2 is assigned to 4 x PCIe Gen2 5GT/s (from APL SoC), 1 x SATA 6G/3G* (from Marvell SATA controller), 4 x
