The cExpress-AL is a COM Express COM.0 R3.0 Type 6 module supporting the Intel Atom processor, Intel Pentium processor and Intel Celeron processor system-on-chip (SoC). The cExpress-AL is specifically designed for customers who need optimized processing and graphics performance with low power consumption in a long product life solution.

The Intel Atom processor, Intel Pentium processor and Intel Celeron processor and support non-ECC type DDR3L dual-channel memory at 1600/1867 MHz to provide excellent overall performance. Integrated Intel Gen9 LP Graphics includes features such as OpenGL 4.3, DirectX 12, OpenCL 2.0; and support for H.265/HEVC, H.264, MPEG2, VC1, VP9, MVC, JPEG/MJPEG hardware decode. Up to three independent displays are available from DDI ports supporting HDMI/DVI/DisplayPort, optional VGA, single/dual-channel 18/24-bit LVDS and optional eDP.

The cExpress-AL is specifically designed for customers with balanced performance/power consumption requirements who want to outsource the custom core logic of their systems for reduced development time. The cExpress-AL has dual stacked SODIMM sockets for up to 8 GB non-ECC type DDR3L memory. Featured IO include a single Gigabit Ethernet port, USB 3.0 ports and USB 2.0 ports, SATA 6 Gb/s ports, and up to 5 PCIe x1 lanes. In addition, SD signals are muxed with GPIO. Support is provided for SMBus and I2C. The module is equipped with SPI AMI EFI BIOS, supporting embedded features such as remote console, CMOS backup, hardware monitor, and watchdog timer. An optional eMMC 5.0 (8/16/32 GB) is supported.
