CompactPCI® PlusIO CPU Card

Low Power Intel® Atom™ SoC (Apollo Lake APL-I E39xx)

The PC6-TANGO is a low power 4HP/3U CompactPCI® PlusIO CPU board, equipped with an Intel® Atom® 39xx-series System-on-Chip processor (Apollo Lake). The PC6-TANGO front panel is provided with two Gigabit Ethernet jacks (option M12-X), two USB 3.0 receptacles, two DisplayPort connectors, and optionally 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.

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 connector pin assignment 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
  • J2 is assigned to 4 x PCIe Gen2 5GT/s (from APL SoC), 1 x SATA 6G/3G * (from Marvell SATA controller), 4 x USB2 ports (from APL SoC), 2 x Gigabit Ethernet (I210IT networking controllers)
* CompactPCI® PlusIO specifies SATA 3G over J2. SATA 6G may be functional but is not guaranteed. The Marvell SATA controller port available via J2 is therefore configured for 3Gbps by default.
** In case of obsolescence, the J2 UHM connector will be replaced by the CompactPCI® 2.0 classic J2 connector. This may reduce high speed backplane transfer in particular applications (PCIe Gen1 2.5GT/s, SATA 1.5G). This does not affect peripherals attached via the P-HSE mezzanine connector.
