Introduction
2.1 Product Description
This credit card sized module is compatible to COM Express™ pin-out Type 1. On 55 mm x 84 mm footprint
nanoETXexpress-SP is a perfect fit for the next generation of low power, ultra-mobile applications that require energy
saving x86 processor performance, high-end graphics, PCI Express and Serial ATA combined with longer battery life.
These include handheld devices for medical or multi-media applications, small mobile data systems and a host of new
applications that have not previously been possible due to size or power consumption limitations. This new COM form
factor is 100 percent compatible with the COM.0 Type 1 with respect to connector location and pin definition. The
Kontron nanoETXexpress-SP COM is based on the highly-efficient Intel® Atom™ Z5XX processor series and Intel®
System Controller Hub single chip that combines the memory controller, graphic engine and I/O in a single, space
saving chipset design. The nanoETXexpress-SP COM offers an unprecedented power consumption / performance ratio
for x86-based ultra-mobile designs. T he nanoETXexpress-SP with Flash and memory on-board supports 1 PCI Express
x1 Port (opt. 2 x1 if no onboard LAN), Serial ATA, LVDS, optional SDVO and High Definition Audio. 10/100/1000
Gigabit Ethernet is designed onboard for high connectivity and 8x USB provides fast and sufficient interfaces for
external peripherals.
2.2 Naming clarification
COM Express™ defines a Computer-On-Module, or COM, with all components necessary for a bootable host computer,
packaged as a super component. Interfaces will provide a smooth transition path from legacy parallel interfaces to
LVDS (Low Voltage Differential Signaling) interfaces. These include the PCI bus and parallel ATA and PCI Express and
Serial ATA.
» ETXexpress® modules are Kontron's COM Express™ modules in basic form factor (125mm x 95mm)
» microETXexpress® modules are Kontron's COM Express™ modules in compact form factor (95mm x 95mm)
» nanoETXexpress® modules are Kontron's COM Express™ modules in the future ultra form factor (55mm x
84mm)
2.3 Understanding COM Express™ Functionality
All Kontron microETXexpress® and ETXexpress® modules contain two connectors; each of it has two rows. The
primary connector has two rows called Row A and Row B. The secondary connector has two rows called Row C and Row
D. On nanoETXexpress® modules only the primary connector Row A and Row B is used.
The primary connector (Row A and Row B) feature the following legacy-free functionality:
» Ethernet
» Serial ATA (SATA)
» USB 2.0
» LVDS/VGA and dual display video
» High Definition Audio (Azalia)
» LPC (low pin count) Bus
» PCIexpress
