Teensy Linux SBC sprouts second Ethernet port

Apr 6, 2007 — by LinuxDevices Staff — from the LinuxDevices Archive — 22 views

SSV has added a new model to its line of miniature ARM-based single-board computers (SBCs) designed to fit into IC-style sockets. The DIL/NetPC ADNP/9200 measures 3.2 x 1.4 inches, comes with Linux, and targets industrial routers, switches, firewalls, and gateways requiring dual Ethernet ports.

According to SSV, the spread of real-time Ethernet concepts such as Profinet and Ethernet Powerlink has created demand within the automation industry for devices with multiple Ethernet ports, given that “in practice, 'regular' Ethernet and real-time Ethernet require separate segments.”

Similarly, safety-critical or time-critical applications now also demand separate LAN segments, the company said.

Whereas older DIL/NetPC models (see Related Stories below) fit into “dual in-line” (DIL) sockets, the ADNP/9200 is designed for use with 128-pin “quad in line” (QIL) JEDEC sockets with 0.1-inch (2.54mm) pin spacing.

The ADNP/9200 uses Atmal's AT91RM9200 SoC (system-on-chip), which is powered by an ARM9 core clocked at 180MHz. On-board memory is surprisingly capacious for such a small device — 64MB of SDRAM, and 32MB of onboard flash.

I/O and other board features include:

  • 2 x 10/100 Mbps Ethernet interfaces
  • 2 x USB host ports (full-speed and low-speed)
  • 1 x USB device port (full-speed and low-speed)
  • 1 x serial peripheral interface (SPI)
  • 3 x serial ports (one with all handshakes)
  • 20-bit general purpose high-speed parallel I/O
  • 16-bit I/O expansion bus
  • ESL (expansion sandwich layer) connector for WSN (wireless sensor network) expansion
  • 1 x interrupt inputs, 4 x chip select outputs
  • Programmable watchdog timer
  • JTAG IEEE 1149.1 test interface
  • In-system programming features
  • 3.3 Volt low power design, supply voltage 3.3 VDC (+- 5%)
  • Supply current 300 mA typ. @ 180 MHz
  • 0 to +70 degrees C operating temperature

The ADNP/9200 comes with an embedded Linux operating system pre-loaded in flash. The OS includes drivers, a TCP/IP protocol stack, and “various servers,” SSV said. A web interface allows easy initial configuration, and a “wide range of firewall and gateway functions” are supported.

The ADNP/9200 is available now as part of an inexpensive “Starter Kit” that comprises the board, along with a baseboard that brings out two RJ45 LAN connectors, two RS232 interfaces, an SD/MMC slot, and a CompactFlash slot, plus USB host and device connectors. Additionally, the baseboard has a “breadboard for making your own adjustments,” SSV said. Pricing was not disclosed.
