tx-reverse-160pxTRITON-TX28, the high-performance ARM9 module

Production-quality system-on-module (SOM) based on 454MHz Freescale i.MX28

tx28-215x275TRITON-TX28 is a low-cost high performance ARM9-based module based on Freescale’s iMX28 microcontroller, implemented on a board with form-factor smaller than a credit card (68mm x 26mm), and ready to be incorporated into your low or medium volume product manufacture or prototype. As well as a high performance 454MHz i.MX28 processor, the TRITON-TX28 modules features 128MB of high bandwidth DDR2-400 RAM, and 128MB NAND Flash, and comes complete with a StarterKit development baseboard, and production quality implementations of Windows CE 6.0, Windows Embedded Compact 7 and Linux 3.x.

TRITON-TX28 includes a comprehensive set of peripherals and interfaces. These include USB 2.0 Host and OTG, two 10/100 Ethernet ports which are IEEE1588 capable, SD Card, UARTs, LCD controller, keypad controller, I2C, I2S, AC’97, SPI, CAN and GPIO. In addition there are 8 analog inputs (5 are used for touch).

The industrial temperature grade TRITON-TX28 also provides the base for our lowest-priced module, the TRITON-TX28S, which is a commercial temperature grade version of the module, with 64MB RAM, single Ethernet controller, and other specification differences.

Mainline Linux, Comprehensive Windows CE 6.0
Linux support for TRITON-TX28 is provided by a mainline ARM-Linux BSP, which means that support is maintained at the latest embedded Linux version, which allows users to leverage support and application compatibility from the open-source community.

TRITON-TX28 also features a particularly comprehensive Windows CE 6.0 BSP which includes support for power-saving measures such as suspend/resume, dynamic voltage and frequency scaling (DVFS), as well as the i.MX28’s dual Ethernet capability.

New TRITON-TX6UL, with 528MHz ARM Cortex-A7 processor and 256Mb RAM is now the lowest-priced member of the TRITON-TX family.

TRITON-TX6UL is fully pin-compatible with TRITON-TX28, and the rest of the family, and runs a Linux 4.4 kernel. The module offers industrial temp. spec (-40 to +85C), and, via alternate pin configurations the possibility of dual Ethernet and up to 6 UARTs.

calendarGuaranteed lifetime is a key reason to choose us – some TRITON products have already been shipping for over 10 years. Each member of the TRITON-TX module family is guaranteed to be available, in small or large quantities for at least 10 years from launch. This is a minimum, with expected lifetimes of 15 years where possible. Direct Insight brought the first system-on-module to market in 1999, and has a unique track-record in maintaining partnership with our customers for the long-term, supporting you throughout the product life-cycle.

euBecause the TRITON-TX modules are manufactured in a high-quality small-batch production facility within the EU, there are never problems with manufacturing standards or with supply. If you order 100 modules and we don’t have them in stock, we will make them. Often, cheap modules are produced in large batches by volume-oriented contract manufacturers in the Far East, and once they are gone, they are gone.
tickOur BSPs for both Linux and Windows CE are complete, and are designed so that you can use them without further development or modification. One of the key advantages of the system-on-module approach is rapid time-to-market, and requires a reliable, production-ready BSP, and a ready-to-roll compatible tools setup. For Linux, we supply a pre-configured VM SDK, and for Windows CE, everything is ready to use with Microsoft’s downloadable toolkit.
compatibleFurther to our 10-year longevity guarantee, additional security is provided by the pin-compatible nature of the TRITON-TX range, which means that suitable baseboard designs can take all the modules from this family, including those based on i.MX25, i.MX27, i.MX28, TI AM3354, i.MX51, i.MX53 and i.MX6, and allows older modules to be replaced by the latest designs, with new features, better price-performance, and renewed longevity.
directinsight-logo-100pxStriving for the best technical support provision to our customers is what makes Direct Insight stand out. Using a system-on-module is all about achieving a quicker, smoother route to project completion. We have supported our customers in many hundreds of system-on-module projects over the last 15 years, and are uniquely placed to assist you.

txmainboardloMainboard-7 provides a complete development environment based on TRITON-TX28, running mainline Linux or Windows Embedded CE 6.0 / Compact 7 out-of-the-box. The development system consists of a baseboard which provides an unpopulated bank of 0.1″ headers for all 200 module pins, plus connectors for all the main module interfaces, and includes additional peripherals such as an SGTL5000 audio codec. Other connectors include USB, Ethernet, SDCard, CAN, RS-232 and RS-485. The Mainboard-7 offers an optional 640×480 capacitive touch screen, and an LVDS output to enable connection of other screen sizes. For production purposes, you will require a custom baseboard, and we are happy to offer baseboard design and manufacture as a service.
The TRITON-TX28 is available in the following standard configuration:

TX28/454/128R/128F/I – i.MX287 processor, 128MB RAM, 128MB NAND Flash, industrial temp. (-40 to +85C)

A version with 256MB RAM, and the lower-cost, commercial temp. TRITON-TX28S with i.MX283 are also available.
