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.

PC6-TANGO • CompactPCI® PlusIO • Intel® Atom™ E39xx Processor (APL-I SoC)

Microprocessor

The PC6-TANGO is equipped with an Intel® Atom™ E39xx series processor (code name Apollo Lake-I aka 'APL-I'). This system-on-chip (SoC) provides integrated graphics, an ECC memory controller and high speed I/O, resulting in a low power platform design. As of current, Intel® offers three CPU SKU versions suitable for the PC6-TANGO, differing mainly in the power consumption, caused by differences in the number of processor cores integrated and internal clock speed.

The processor is housed in a FCBGA-1296 package for direct soldering to the PCB, i.e. the chip cannot be removed or changed by the user.

Power is applied across the CompactPCI

connector J1 (5V). The processors core, graphics and

memory voltages are generated by switched voltage regulators sourced from the 5V plane.

Thermal Considerations

The PC6-TANGO is equipped with a passive heatsink. Its height takes into account the 4HP envelope of a CompactPCI® board. Dependent on the targeted APL-I SoC SKU and ambient temperature, many applications may not require additional cooling.

However, a reasonable forced vertical airflow through the system enclosure (e.g. bottom mount fan unit) may be required for demanding applications and for higher ambient temperatures. The maximum temperature on top of the CPU case must not exceed 100°C e.g. for the E3940.

The APL E3900 AtomTM processors support Intel's Enhanced SpeedStep® technology, enabling dynamic switching between multiple core voltages and frequencies depending on core temperature and currently required performance. The processors are able to reduce their core speed and core voltage in multiple steps down. Additionally a reduction of the graphics core clock and voltage is possible. This results in a reduction of power consumption and heat dissipation.

Do not try to remove the PC6-TANGO heatsink by yourself, since it is bonded to the CPU by a Phase-Change-Material (PCM), in order to improve the heat flow between the APL and the heatsink.

Main Memory

The PC6-TANGO features a total of 8GB DDR3L SDRAM with support of ECC (Error Correction Code). 8GB is the maximum memory size supported by the APL-I SoC. All 18 memory devices are directly soldered to the board (Memory Down), with a clock frequency of 1600MHz.

You may find external documents which specify a maximum DDR3L speed of 1866MT/s for the APL. However, this is valid for non ECC designs only.

Graphics Subsystem

The APL-I SoC is provided with an integrated GPU, running at up to 650MHz clock, based on the 9

generation Intel® graphics. For industrial applications and optimum reliability however, Intel® recommends to operate the GPU at 400MHz fixed clock.

The PC6-TANGO offers two DisplayPort (DP) receptacles in the front panel, for individual use or an extended desktop application. The VESA DDC standard is supported, allowing to read out important display parameters, e.g. the maximum supported resolution from the attached monitor. DDC power +3.3V is delivered via electronic switches to protect the board from an external short-circuit condition (1.5A) and to prevent back driving current flows.

Graphics drivers for the Intel® GPU are an inherent part of popular operating systems, or can be downloaded from the Intel® website.

LAN Subsystem

The Ethernet LAN subsystem is comprised of up to four Gigabit Ethernet ports. Two Intel® i210IT Gigabit Ethernet controllers are provided to support the front panel RJ45 jacks (backwards compatible to 10Base-T and 100Base-TX). Another two i210IT NICs are available as an option, for rear I/O usage via the J2 backplane connector. Each port includes the following features:

< 1000Base-Tx (Gigabit Ethernet), 100Base-TX (Fast Ethernet) and 10Base-T (Classic Ethernet)

capability

< Half- or full-duplex operation < IEEE 802.3u, 802.3ab Auto-Negotiation for the fastest available connection < Jumperless configuration (complete software-configurable)

Two bicoloured LEDs integrated into the dedicated RJ-45 connector in the front panel are used to signal the LAN link, the LAN connection speed and activity status. A further bicoloured LED in front panel labelled EB displays the state of the optional backplane network ports.

Due to limited internal resources of the APL, each GbE NIC device is connected via its PCI Express® lane to an on-board PCI Express® 1:5 port packet switch (Diodes PI7C9X2G606PR), thus sharing a common PCIe Gen2 lane (5Gbps) from the APL-I SoC. With its 5Gbps uplink, the PCIe switch can smoothly control all four GbE NICs simultaneously at maximum networking speed. However, across its remaining downstream port the PCIe switch would also feed an optional on-board SATA 6G controller. For applications which use this hardware configuration intensely, a loss in networking performance may temporarily occur.

The MAC addresses (unique hardware number assigned to any Ethernet NIC) are stored in dedicated FLASH/EEPROM components.

The Intel Ethernet software and drivers for the i210IT are available for download from Intel®.

Any of the i210IT controllers supports the IEEE 1588 Precision Time Protocol, important for TSN (Time Sensitive Networking) applications. In addition, the first NIC (which is connected to the upper RJ45 jack within the front panel) is configured to generate Pulse per Second (PPS) and Pulse per Minute (PPM) signals for output via the jumper J-GP and to the backplane connector J2. These signals can be used to trigger events on external hardware such as mezzanine side boards or peripheral cards. The following routing can be enabled by UEFI/BIOS settings:

< Pulse per Second (PPS): J-GP Pin 1 and CompactPCI® J2 (signal SATA-SCL J2-D14) < Pulse per Minute (PPM): CompactPCI

J2 (signal SATA-SDO J2-D13)

Serial ATA Interface (SATA)

The PC6-TANGO provides a total of up to four serial ATA (SATA) 6Gbps ports, suitable for attachment of mass storage devices. Two ports are derived directly from two the APL-I SoC; another two ports are available as an option via an on-board SATA controller.

The APL SATA port P0 is in use for an on-board CFast™ connector. CFast™ cards are available up to 512GB storage capacity as of current, sufficient for typical operating system installation and application programs.

The APL SATA port P1 is wired to the mezzanine connector HSE, for optional usage with a low profile mezzanine module such as the C48-M2 (M.2 SATA SSD storage).

As an option, the PC6-TANGO can be equipped with a discrete on-board SATA controller in addition, providing another two SATA 6Gbps ports. The Marvell 88SE9170 is an SATA 6Gbps I/O controller, connected to the system via PCI Express®. One of the 88SE9170 SATA ports is wired to the mezzanine connector HSE, and the other to the backplane connector J2. The 88SE9170 shares a common PCIe lane from the APL SoC with the on-board NIC devices, by means of a PCI Express® packet switch. Therefore the maximum throughput of the 88SE9170 SATA ports may be somewhat reduced compared to the APL native SATA ports.

As mentioned, a single SATA port is used to supply the CompactPCI® PlusIO SATA interface on the backplane or rear I/O module, via the J2 UHM connector. Please note, that the CompactPCI® PlusIO specification refers to SATA data rates of 1.5Gbps and 3Gbps. EKF has tested successfully also 6G over the backplane with sample devices, but cannot guarantee this data rate under any condition. Other devices and other backplane brands/types in use may cause a different result. If in doubt, the Marvell SATA controller should be initialized for 3Gbps. EKF recommends that customers validate their particular SATA 6G application thoroughly, since SATA channel data errors can decrease the performance considerably.

A bicolor LED named HD located in the front panel, signals the activity status of any APL SATA device (green) or 88SE9170 SATA device (yellow).

Windows® drivers and software for the 88SE9170 is provided by Marvell and can be downloaded from the EKF website.

PCI Express® Interface

The PC6-TANGO is provided with four PCI Express® (PCIe) Gen 2 lanes for rear I/O expansion, derived from the APL-I SoC (PCIe P0-P3), and available via the backplane connector J2. By software strapping, these lanes can be configured as 4 PCIe links x1, or one link x4, for use on a hybrid backplane with CompactPCI® Serial peripheral slots, or on a rear I/O module.

Another two PCI Express® lanes from the APL-I SoC are in use on-board.

The APL PCIe lane P4 is used as upstream port for an 1:5 PCIe packet switch, which controls all four i210IT GbE controllers, and in addition an optional SATA controller.

The APL PCIe lane P5 is connected to the PCIe to PCI bridge, which allows to control up to eight CompactPCI® Classic peripheral slots across the backplane connector J1.
