Based on Texas Instruments' brand new DM6446 processor. It combines a DSP with an ARM9 Core and offer multiple I/Os like Video-Out, Video-In, USB, Ethernet, ATA cF and 3x UART. The HW video acceleration unit makes it a perfect fit for industriel video applications and vision systems. The tiny footprint of 66x77mm² allows the use in smallest devices. The MPX6446 forms part of the new MPX standard. The new connector technology allows mounting in both directions and stacking of modules with various interface boards. Versions for extended temperature (-40°..+85°C) are available.


The CRX03 Carrier Board covers the physical layers for the MPX 6446 DSP-Module. It is designed not only for evaluating the MPX module during the design phase but it will fit into many applications directly. As the MPX technology allows stacking of boards, application-specific functionality can be realised on dedicated PCBs that may be mounted on top of a CRX03-MPX combination.
