Long-life Mini-ITX board features Core i3, dual display support

Sep 22, 2011 — by Eric Brown — from the LinuxDevices Archive — 28 views

BCM announced an industrial-focused Mini-ITX single board computer (SBC) equipped with a 2.13GHz Intel Core i3 processor and Intel HM55 chipset, promising long-life availability until 2017. The IX55HM supports up to 8GB DDR3 memory, and offers PCIe and mini-PCIe expansion, SATA II storage support, and real-world ports that include dual gigabit Ethernet connections, according to the company.

Conforming to the 6.7 x 6.7-inch Mini-ITX form factor, the IX55HM is equipped with the Intel HM55 chipset and a Core i3-330E CPU. From Intel's 2010 crop, this CPU is clocked at 2.13GHz. 


The IX55HM supports up to 8GB DDR3 memory, according to BCM. The SBC is also said to feature both PCI-Express (PCIe) x16 and Mini-PCIe expansion slots.

Dual display capability is provided, with combinations of either VGA and either HDMI, DisplayPort, or 24-bit LVDS. All these display interfaces are served up via real-world coastline ports except for LVDS. In addition, for panel control via LVDS, two dual channels with 24-bit resolution are also supported, as well as a connection for backlight control, says the company.

Other coastline ports include dual gigabit Ethernet ports, four of the eight available USB 2.0 ports, and one of the two RS-232 ports, says BCM. Dual PS/2 ports, as well as audio connections for the dual-channel Realtek HD audio chipset, are also externally available.

Internal connections include four SATA II ports and parallel, 8-bit GPIO "with TTL level," thereby simplifying sensor and actuator connectivity, says the company.

Status monitoring is provided for voltage, cooling fan speed, and CPU temperature, with the latter supported with auto throttling controls that kick in at a defined temperature limit. There's also a watchdog timer, as well as a Preboot eXecution Environment (PXE) interface for activating the board via Ethernet, says the company.

A standard 20-pin ATX power supply connector and a four-pin, 12V input connector are provided, and power consumption is typically less than 19 Watts, claims BCM. A three-step fan control is said to ensure low noise levels, and operating temperature support is said to range from 32 to 140 deg. F. The SBC is available with long-life support until 2017, says the company.
