Introduction 1

1. Introduction

The cExpress-BT2 is a COM Express® COM.0 R2.1 Type 2 module supporting the Intel Atom® E3800 processor

and Intel® Celeron® processor, memory controller, and graphics processor on a single-chip design. The cExpress-

BT2 is specifically designed for customers who need high-level processing and graphics performancewith low

power consumption in a long product life solution.

The cExpress-BT2 features the Intel Atom® E3800 processor and Intel® Celeron® processor supporting non-ECC

type DDR3L dual-channel memory at 1066/1333 MHz to provide excellent overall performance.

Integrated Intel® 7th Generation HD Graphics includes features such as OpenGL 3.1, DirectX 11, OpenCL 1.1

support for H.264, MPEG2, VC1, VP8 hardware decode. Graphics outputs include VGA and dual-channel 18/24-bit

LVDS. The cExpress-BT2 is specifically designed for customers with high-performance graphics processing

requirements who want to outsource the custom core logic of their systems for reduced development time.

The cExpress-BT2 has dual stacked SODIMM sockets for up to 8 GB non-ECC type DDR3L memory. In addition,

an onboard eMCC memory is supported (optional, 8GB/16GB/32GB).

The cExpress-BT2 features a single onboard Gigabit Ethernet port, USB 2.0 ports, PATA and SATA 3 Gb/s ports,

and PCI 2.3. 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.
