Product Description
The ETX-PVR is an exceptionally high integration, high performance, rugged, and high quality Computer-
on-Module (COM), which contains all the component subsystems of an ATX motherboard plus the
equivalent of up to 2 expansion boards. Based on the Intel® Atom™ N455 and D525 processors, the
ETX-PVR provides designers a complete, high performance embedded processor that conforms to the ETX
V3.02 specification.
The Intel Atom N400 and D400/D500 series CPUs integrate processor cores with Graphics and Memory
Hubs (GMHs), providing low-power, high-performance processors, memory controllers for up to 2GB of
DDR3 memory, and graphics controllers which provide LVDS and VGA signals for most LCD video panels
and CRT monitors.
The ICH8-M chipset provides controllers for the I/O Hub (Southbridge) featuring four USB ports, one Ultra
DMA 33/66/100 IDE port supporting two IDE devices, one HD Audio link, two SATA ports, one Ethernet
interface, one PCI interface, one SMBus interface, one LPC bus, and one speaker port. The ETX-PVR
provides legacy interfaces through the SMSC SCH3112I-NU Super I/O featuring two serial ports, one
parallel/floppy port, and one PS/2 keyboard and mouse port.
Among the many embedded-PC enhancements on the ETX-PVR that ensure embedded system operation
and application versatility are a Watchdog Timer, remote access support, battery-free boot, and OEM logo
customization (Splash Screen).
The ETX-PVR is particularly well suited to either embedded or portable applications and meets the size,
power consumption, temperature range, quality, and reliability demands of embedded system applications.
The ETX-PVR requires a single +5V power supply.
