PXA270 and PXA255 CPU modules and Dev Kits
——
" Quite a few vendors are supplyingPXA255boards these days,andStrategic Test’s wares seem like very viable contenders for pre-fabbedandtested embeddedmodulesfor portableandother low power applications." Alex Mendelsohn, EEProductCentre
Overview
The TRITONmodulesare based on the Intel XScalePXA270orPXA255processor. There are now 6 different TRITONmodulesin the range so that you can choose the most economic versions for your application.
Pedigree
• 2002 : World’s first PXA250 embedded module
• 2003 : World’s firstPXA255embedded module
• 2004 : Widest range of PXA255 modules
• 2004 : Triton-270 is World’s first embeddedPXA270module
• 2004 : TDK-3 is World’s first development kit supporting WinCE 5.0 optimized forPXA270
TRITON models
A comparison of the key features of each module is available as a PDF.
XScale
Intel’s new XScale processor family increases efficiency and decreases processor power consumption. The Intel®XScale microarchitecture is based on the solid and widely used foundation of the Intel® StrongARM technology.
Optimized for the development of highly efficient mobile internet devices, and for network infrastructure applications, Intel® StrongARM and Intel® XScale are compatible with the ARM v.5TE architecture, which in turn guarantees the compatibility of software solutions.
Turbo mode enables the processor to scale its performance as high or as low as necessary in a single clock cycle, which helps conserve battery life while still meeting performance requirements. In addition, the new micro-power management features for these devices allow the processors to potentially use less than half the power at the same performance levels of the Intel StrongARM SA-1110 applications processor.
Operating Systems
TheDevelopmentKitsare normally supplied with Linux, Windows 5.0, 4.2 CE.NET and QNX are also available, although not all TRITON modules are currently supported - contact us for more info.
Note that the OS is only normally pre-installed in the TRITON Flash memory when aDevelopment Kit is supplied. When modules only are ordered, the OS is not pre-installed unless ordered as an option.
RedBoot
Modules are always supplied with pre-installed Redboot firmware. Redboot supports several low-level-debugging options and file download via serial XModem or FTP via ethernet. These files can additionally be stored into the permanent flash-memory to be started by command or power-on.
