These long-life processors built on the Intel® 14nm Micro-architecture (i.e. Kaby Lake and Skylake) feature native PCI Express 3.0 links to the system backplane and utilize a 8GT/s DMI3 interface to the board’s Intel® C236 PCH.  Additional embedded and non-embedded processor options are available for use on the TKL8255 system host board.

 

The board’s two dual-channel DDR4-1866/2133 memory interfaces support four standard DIMM sockets for a 64GB maximum system memory capability when using 16GB DDR4 DIMMs.

 

Intel® Xeon® processor options feature Intel® HD Graphics P630 or P530.  Intel® Core processor options feature Intel® HD Graphics 630 or 530.  Both graphic engines feature DirectX 12 and OpenGL 4.4 support and can output 4K resolutions (4096×2304 @60Hz when utilizing DisplayPort output).

Memory

64GB maximum when utilizing 16GB DDR4 DIMMs.  The board’s two, dual-channel DDR4-2133 memory interfaces have two DIMM slots apiece that support unbuffered, ECC PC4-17000 DDR4 memory DIMMs.

 

All available TKL8255 processor options support the DDR4-2133 maximum memory interface speed.

 

Note: The Intel® Core™ i7 and Intel® Core™ i5 processor options do not support ECC memory.  ECC memory DIMMs are cost effective and can be used with these processor options, but the processors will ignore the ECC functionality of the memory DIMMs.

1 – DisplayPort – Located on the I/O bracket of the TKL8255, DisplayPort is a modern video cable connection capable of supporting many advanced graphical capabilities, including High-bandwidth Digital Content Protection (HDCP), DisplayPort Content Protection (DPCP) “4K” resolutions, up to 8 channels of 24-bit, 192kHz audio and Stereoscopic 3D video output.  The DisplayPort cable has an integrated locking mechanism for application security in high-vibration environments.

 

Multiple video connections are an inherent system design advantage of Trenton’s TKL8255 featuring the SHB’s processor options and the Intel® C236 chipset.  The Intel® HD Graphics 530 technology is featured in the graphics controller engine of these Skylake processor options. Utilizing twenty-four (24) execution units, Intel HD Graphics 530 provides significant gains in 3D performance while lowering power consumption over previous graphical engine implementations.  This graphics engine supports a total of three display interfaces with a base operational frequency of 350MHz and maximum shared memory of 1.7GB.  Some processor options support an increased Dynamic Frequency boost when additional graphical computational power is required.  The integrated graphics controller of the board’s processor dynamically utilizes a portion of the system memory based on the OS and the amount of memory installed.  All processors support maximum video resolutions of 4096×[email protected] via DisplayPort.

On-Board Interfaces

Four USB 3.0 and Six USB 2.0 ports – The two on the I/O bracket, and two located on one of the dual-interface onboard headers support the USB3 device interface while one additional dual-interface onboard header and the four routed to SHB edge connector “C” for use on a PICMG 1.3 backplane support six USB2 interfaces.

 

All six SATA ports on the TKL8255 support 600MB/s data transfers. In other words, all ports support SATA Gen 3.0 devices.  The ports may be used for either independent SATA drive operation, “JBOD” or in RAID 0,1,5 and 10 drive array system configurations.

Watchdog Timer

The TKL8255 provides a programmable watchdog timer with programmable timeout periods of 100 msec, 1 second, 10 seconds or 1 minute via board component U11.  When enabled the WDT (i.e. U11) will generate a system reset.  WDT control is supplied via the General Purpose IO pins from the Intel® C236 Platform Controller Hub (PCH).  The PCH’s GPIO_LVL2 register controls the state of each GPIO signal.  This 32-bit register is located within GPIO IO spaces.  The GPIO_BASE IO address is determined by the values programmed into the PCH’s LPC Bridge PCI configuration at offset 48-4B(h).

 

See the watchdog timer section in the specifications chapter of the TKL8255 Hardware Manual for more detailed information and a WDT programming example.
