TRITON-320 is a self-contained production-quality module, based on Marvell's new powerful, ultra-low-power PXA320 microcontroller - with full software support including Linux 2.6 and Windows Embedded CE 6.0 - ready to be designed into a production embedded system.
For development you simply plug the TRITON-320 into its StarterKit-4 development baseboard, and then in production the StarterKit is replaced by your own custom breakout base (which may be designed and manufactured by us on your behalf).
Because the TRITON system includes a production quality Board Support Package (BSP) for Windows Embedded CE 6.0 and Linux 2.6 and production quality module, project times are cut dramatically.
TRITON-320 includes an 806MHz Marvell PXA320 processor, 64MB ultra-low power 1.8v 260MHz DDR mobile SDRAM and 128MB NAND Flash. The PXA320's integrated LCD controller permits direct connection of an LCD screen, and the MultiMedia Card interface permits simple integration and extension into a target system. Glueless connection to a DM9000 Ethernet controller is implemented in the StarterKit-4.
TRITON-320 also features a 3.3V, 16-bit multiplexed external memory interface, a high-efficiency programmable PMIC power supply which is integrated with the PXA320's Wireless SpeedStep power management, and the availability of the processor's I/O via a standard DIMM200 socket. The overall size of TRITON-320 is 67.6mm x 26mm x 4.2mm.
The module operates from a single 3.0 to 5.5v supply, and ships with Redboot firmware installed, and with full Linux 2.6, or Windows Embedded CE 6.0 BSP when supplied with the StarterKit-4 development system.
The Marvell PXA320 combines ultra-low-power operation with outstanding multimedia performance, and features an extended instruction set which includes Wireless MMX-2 instructions for enhanced image processing and graphics capability.
PXA320 is capable of being dynamically configured to run at reduced supply voltage and reduced clock rate, and the TRITON-320 and associated BSPs support this facility. Compared with the PXA270, enhancements include direct support of NAND Flash, an enhanced DDR SDRAM controller, additional low-power modes, improved LCD controller and graphics engine, higher resolution camera interface, and an additional Multimedia Card interface. PXA320 is an ideal target for use with Windows Embedded CE and embedded Linux for high performance applications.
For development purposes, the TRITON-320 plugs into the StarterKit-4 baseboard via its DIMM200 connector. This combination, with optional touch-screen display is supplied as a complete development kit running Linux or Windows CE 6.0. The Linux BSP ships with a complete GCC toolchain, allowing users to modify the BSP as required. Windows CE source code is also available.
The StarterKit-4 includes connectors for the I/O facilities offered by the PXA320 processor and TRITON-320, including a CompactFlash type II socket, SD/MMC card socket, 3 x RS232 connectors, USB-device and USB-Host connectors, and a D-SUB15 VGA connector for the video DAC. In addition, there is a DM9000 10/100 BaseT Ethernet, a UCB1400 audio codec and touchscreen controller with two 3.5mm audio connectors. The on-board power supply has an 6 - 24V input range and both 3.3v and 5v are available on-board.

There is also a JTAG interface, which can be used for the connection of a debug probe, such as the EPI Majic emulator which works with both Platform Builder and GDB.
To facilitate creation of a production baseboard, full schematics are provided for the StarterKit-4. We offer a custom baseboard design and production service, and can manufacture and deliver your complete product.
The optional Xenarc 700TSV features a 7” TFT LCD monitor and touch-screen, with physical resolution of 800 x 480. The screen interfaces to TRITON-320 via a video output, and the touch facility via a USB port on the StarterKit-4. This provides a useful starting point for out-of-the-box operation, but an LCD touch-screen suitable for the application can easily be connected directly to the PXA320 display controller via supplied headers, and is easily integrated by setting parameters in the generic display driver supplied with both BSPs.
The table below shows the complete list of PXA320 interfaces, plus those additional facilities added by the module and the baseboard. A list of connectors on the baseboard is available here. Further details of the Windows Embedded CE 6.0 BSP and Linux 2.6 BSP are also available.
