Tiny Monahans module ships with Linux

Feb 1, 2007 — by LinuxDevices Staff — from the LinuxDevices Archive — 4 views

Strategic Test is shipping an SODIMM-sized processor module based on Marvell's XScale PXA320 (“Monahans P”) processor. The Triton-320 processor module is available with a development kit that includes a 6 x 4-inch carrier board and a ready-to-use Linux 2.6.17 embedded operating system.

Strategic Test appears to have initially announced the Triton-320 module last October. However, at that time it was designated the “Triton-290,” possibly assuming that Marvell would adopt “PXA29x” naming when Monahans processors finally shipped. Instead, Marvell, which acquired Monahans from Intel last June, used a PXA3xx naming scheme when it began shipping Monahans processors five months later. Prior to that, Intel had sampled the chip for several years.

The Triton-320 is the latest in Strategic Test's line of SODIMM-sized XScale modules. Earlier Triton modules include the Triton-270, based on a PXA270 (“Bulverde”) processor, and the Triton-255 and Triton-250, based respectively on PXA255 and PXA250 (“Cotula”) processors. The modules are meant to be used as macrocomponents, plugged into slots on custom baseboards in shipping product designs.

In addition to a PXA320 clocked at 806MHz, the Triton-320 has 128MB of onboard SDRAM, and 64MB of flash memory. It measures 2.6 x 1 x 0.16 inches (67.6 x 26 x 4.2 mm).

For evaluation and development purposes, the Triton-320 module is available as part of a Triton Development Kit 4 (TDK-4). The kit includes a 6 x 4-inch baseboard that provides an SODIMM socket to accommodate the module. Other features of the baseboard are:

  • UCB1400 CODEC and touchscreen controller
  • CompactFlash socket
  • SD/MMC socket
  • 10/100 Mbps Ethernet
  • USB 1.1
  • 3 x RS232
  • JTAG interface
  • LCD and VGA connectors
  • Wide range 5V to 40VDC power supply protected against in-vehicle transients


The Triton-320 is immediately available as part of the TDK-4 development kit, preinstalled with either Linux or Windows CE. The kit, priced at $4,250 with a year of support and a 2-year warranty, includes carrier board schematics, a manual, cables, power supply, and a software CD with both Linux 2.5.17 and Windows CE 6.0 operating systems.

UK-based distributor Direct Insight expects to stock the Triton-320 module in February, with quantity pricing below $150.
