PXA270-based SBC offers camera interface

Sep 25, 2007 — by Jonathan Angel — from the LinuxDevices Archive

Arcom has announced a new single-board computer (SBC) based on a PXA270 processor and available with a Linux development kit. The PC/104 form-factor Titan features a “quick capture camera interface,” and is said to be ideal for “power-sensitive embedded communications and multimedia applications.”

Titan in name but not in size, the RoHS-compliant SBC measures 3.8 x 3.6 inches. Efficient design and several dynamically adjusted sleep modes are said to reduce typical power consumption to just 1.5 watts.

The module's PXA270 processor is clocked here at 520MHz. The module supports up to 128MB of soldered-on DRAM and up to 64MB of flash memory, and an onboard battery provides backup for 256KB of static RAM.

Citing a “comprehensive list of integrated peripherals,” Arcom says the Titan comes with dual USB ports, an Ethernet controller, five UART channels, and a control for a 4- or 5-wire touchscreen. It also has direct support for LVDS output, according to the company.

While Arcom did not provide further details of the quick-capture camera interface (the connector seen on the lower left of the board in our photo), this technology is an integral part of the PXA270 platform. Thus, as on smartphones that use this processor, the Titan could capture full-motion video and stills with a resolution up to 4 megapixels.

Immediately to the right of this connector can be seen another for audio, including mic and line in, and amplified audio output. To the right of that, there is the Titan's integral SD/SDIO/MMC card socket.

Key features and specifications cited by Arcom for the Titan include:

  • Processor — PXA270, clocked at 520 MHz
  • Memory — up to 128MB of soldered DRAM; up to 64MB flash; 256KB of battery-backed SRAM
  • Video:
    • supports TFT/STN flat panels up to 640 x 480 x 18-bit color
    • 4 or 5 wire touchscreen support
    • optional LVDS

  • Audio — AC'97 audio controller
  • Networking — 10/100 Ethernet controller (Davicom DM9000A)
  • Other I/O ports:
    • 2 x USB 2.0 host ports (can also be configured for one host, one client)
    • 5 x 16550 UARTs (4 x RS-232; 1 x RS-422/485)

  • Expansion:
    • 8/16-bit PC/104 interface
    • SD/SDIO/MMC card socket

  • Power:
    • +5V DC input @ 350 mA, typical
    • on-board 3V lithium battery, for RTC and SRAM backup

  • Dimensions — 3.8 x 3.6 inches (96 x 91 mm)
  • Weight — 3.2 ounces (90 grams)
  • Operating temperature — -20 to +70 deg. C standard; -40 to +85 deg. industrial

Expected to be available in October, the Titan is supported by “ready-to-run” development kits for both embedded Linux and Windows CE 5.0. Each kit consists of a Titan preloaded with the embedded operating system, along with all documentation and needed tools, Arcom said.
