Express-BD74
Introduction 1
1. Introduction
The Express-BD74 is a COM Express® COM.0 R3.0 Basic Size Type 7 module supporting the 64-bit Intel® Xeon®
processor D (formerly “Broadwell-DE”) system-on-chip (SoC) with up to 4 SO-DIMMs to boost system performance.
The Express-BD74 is specifically designed for customers who need excellent computing performance with
balanced power consumption and multiple 10G Ethernet connectivity in a long product life solution.
The Express-BD74 features Intel® Virtualization Technology (including VT-x, VT-d, EPT), Intel® Hyper-Threading
Technology (up to 16 cores, 32 threads), Intel® Trusted Execution Technology, Intel® AES-NI Technology, and
4 SO-DIMMs to provide a maximum of 128GB DDR4 ECC (or non-ECC) memory capacity and dual-channel
memory design at 1866/2133/2400 MHz (dependent on SoC SKU) for excellent overall performance.
An integrated Intel® 10G Ethernet controller supports two 10GBASE-KR interfaces, relevant sideband signals and
NC-SI. The Express-BD74 is designed to serve customers with optimized computing capability per watt and high
speed connectivity requirements who want to outsource the custom core logic of their systems for reduced
development time.
Input/output features include 24 PCIe Gen3 lanes, up to 8 PCIe Gen2 lanes, a single onboard Gigabit Ethernet port,
USB 3.0/2.0 ports, and SATA 6 Gb/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, hardware monitor,
and watchdog timer.

Memory Dual channel ECC (or non-ECC) 1866/2133/2400 MHz DDR4 memory up to 128GB in
four SODIMM sockets (two on top, two on bottom)
Note: Supported memory frequencies may vary between processor SKUs.
Embedded BIOS AMI UEFI with CMOS backup in 16MB SPI BIOS
Chipset Integrated in SoC
2.2. Expansion Busses
PCI Express 16 PCI Express Lanes Gen3 (CD):
Lanes 16-31 (four controllers, can be configured to 1 x16, 2 x8 or 4 x4/x2/x1)
8 PCI Express Lanes Gen3 (AB):
Lanes 8-15 (two controllers, can be configured to 1 x8 or 2 x4/x2/x1)
Up to 8 PCI Express Lanes Gen2 (AB/CD):
Lanes 0-7 (two controllers defined by PICMG, can be configured to x4, x2, x1)
Notes:
•PCIe lane 7 is supported by build option, in place of GbE
•Although Broadwell-DE platform supports eight roots on Lanes 0-7, the PICMG COM.0
R3.0 specification for Lanes 0-7 states: “Type7 module may support eight x1 root hubs.
It is expected that future generation products may limit the number of available root
hubs.”
Other •LPC bus
•SMBus (system)
•I2C (user)
