1GHz SBC drives dual displays

Jul 2, 2010 — by Eric Brown — from the LinuxDevices Archive — 3 views

Advantech announced a 3.8 x 3.5-inch single board computer (SBC) that offers dual display capability. Built around a DM&P Vortex86DX processor clocked at 1GHz, the PCM-3343 board is equipped with CompactFlash and IDE storage interfaces, and offers dual Fast Ethernet ports, four USB ports, and interfaces including serial, I2C, and GPIO, says the company.

The Advantech PCM-3343 uses DM&P's x86-compatible Vortex86DX processor clocked to 1GHz, which offers a floating point unit (FPU), says Advantech. The Vortex86DX is said to be paired with a SMI SM712 graphics chipset that drives resolutions up to 1024 x 768 resolution for CRT, LVDS, or TFT. The SBC also supports dual display capability between a CRT monitor and either of the two 24-bit flat-panel technologies, says the company.

Equipped with 256MB DDR2 333MHz SDRAM (or twice that upon request), the PCM-3343 supplies CompactFlash and IDE interfaces for storage, says Advantech. A 4MB SPI flash disk is said to be optional.The SBC also supports PC/104 expansion, says the company.

The PCM-3343 supports two 10/100 Ethernet ports, one via the Vortex86DX, and the other via a separate LAN controller, says Advantech. Additional I/O includes interfaces for four USB 2.0 ports, four serial ports, an I2C port, keyboard/mouse, and GPIO.
