The cExpress-BT is a COM ExpressR COM.0 R2.1 Type 6 module supporting the Intel Atom processor E3800 Series and Intel Celeron N2900/J1900 processor SoC (codename: Bay Trail). The cExpress-BT is specifically designed for customers who need high-level processing and graphics performance with low power consumption in a long product life solution.
The Intel Atom processor E3800 and Intel Celeron N2900/J1900 processor support non-ECC type DDR3L dual-channel memory at 1066/1333 MHz to provide excellent overall performance.
Integrated Intel Gen7 HD Graphics includes features such as OpenGL 3.1, DirectX 11, OpenCL 1.1 and support for H.264, MPEG2, VC1, VP8 hardware decode. Graphics outputs include VGA, DDI ports supporting HDMI/DVI/DisplayPort and optional dual-channel 18/24-bit LVDS.
The cExpress-BT 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-BT has dual stacked SODIMM sockets for up to 8 GB non-ECC type DDR3L memory. In addition, an onboard miniSD card slot and onboard eMCC memory (optional, 8GB to 64GB) are supported. The cExpress-BT features a single Gigabit Ethernet port, USB 3.0 ports and USB 2.0 ports, and SATA 3 Gb/s ports. 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.
