The cExpress-KL is a COM Express COM.0 R2.1 Type 6 Compact size module featuring the 64-bit 7th Generation Intel Core i7/i5/i3 and Intel Celeron Ultra-Low TDP processors (formerly «Kaby Lake U») with CPU, memory controller, graphics processor and I/O hub on a single chip.
Leveraging the benefits provided by the 7th generation Intel Core and Celeron System-on-Chip, the cExpress-KL is specifically designed for customers who need optimum processing and graphics performance with suitable power consumption using Intel’s Configurable TDP in a long product life solution.
The cExpress-KL’s Intel processors support Intel Hyper- Threading Technology (up to 2 cores, 4 threads) and up to 32 GB of non-ECC DDR4 dual-channel memory at 1866/2133 MHz in dual stacked SODIMM sockets to provide excellent overall performance. Integrated Intel Generation 9 Low Power Graphics includes features such as OpenGL 4.4/4.3, DirectX 11.3/11, Intel Clear Video HD Technology, Advanced Scheduler 2.0, 1.0, XPDM support, and DirectX Video Acceleration (DXVA2) support for AVC/VC1/MPEG2/HEVC/VP8/JPEG hardware decode and AVC/MPEG2/HEVC/VP8/JPEG hardware encode.
Graphics outputs include dual-channel 18/24-bit LVDS (eDP by build option), two DDI ports supporting HDMI/DVI/DisplayPort and VGA (by build option). The cExpress-KL is specifically designed for customers with high-performance processing graphics requirements who want to outsource the custom core logic of their systems for reduced development time.
The cExpress-KL features a single onboard Gigabit Ethernet port, up to six PCIe Gen3 ports (build option), four USB 3.0 ports, four USB 2.0 ports, and three SATA 6Gb/s ports. Support is provided for SMBus and I2C. The module is equipped with SPI AMI EFI BIOS with CMOS backup, supporting embedded features such as remote console, CMOS backup, hardware monitor, and watchdog timer.
