1. Introduction

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
th
7 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, support by project basis). 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
2
USB 3.0 ports, four USB 2.0 ports, and three SATA 6Gb/s ports. Support is provided for SMBus and I C. 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.
