CompactPCI board touted for 10 Watt power draw

Sep 18, 2009 — by Eric Brown — from the LinuxDevices Archive — 2 views

Kontron announced a 3U CompactPCI board based on the Intel Atom N270, boasting soldered components and 10 Watt power consumption. The Linux-ready CP305 comes in a 4HP version with dual gigabit Ethernet and USB 2.0 ports, or a developer-focused, dual-slot 8HP version with additional I/O, says Kontron.

The CP305 is built around the 1.6GHz Intel Atom N270 CPU, and mated with the usual Intel 945GSE Express Chipset and ICH7-M I/O Controller Hub, says Kontron. The board is available with up to 2GB of DDR2 memory, which is soldered to the board for greater reliability in harsh environments, says the company.

The standard, single-slot 4HP version of the CP305 offers dual gigabit Ethernet ports, dual fast Ethernet ports, four USB 2.0 ports, two SATA interfaces, VGA port, and two serial ports. The I/O is more or less equally divided between front and rear I/O (see block diagram and spec list below).

A dual-slot 8HP version targeted primarily at system designers adds more front-facing I/O, including two more USB ports, and an additional COM port. It also offers a DVI port, enabling dual-monitor displays, says Kontron. The 8HP version also provides a disk slot that can hold a 2.5-inch SATA hard disk drive (HDD) or solid-state drive (SSD). Port details for the 4HP and 8HP are shown in the image below on the left and right, respectively.

Both versions offer a convection system design that can withstand temperatures up to 140 deg. F (60 deg. C), and an extended temperature version is in the works, says Konron. The CP305 is said to offer long-life availability, and is said to be compliant with the EN50155 European railways ruggedization standard.
