Embedded Module TQMa8Xx4 Embedded Cortex®-A35 module based on i.MX8X with high computing power combined with high-speed interfaces.

Arm® Cortex®-A35 based on i.MX8X

  • Graphics with 3D GPU support
  • Security functions
  • Integrated 1x Cortex M4 CPU (Real Time / Security)
  • Low power consumption (typ. 4 W)
  • DSP for audio processing
  • 3x CAN FD
The Minimodule TQMa8Xx4 is based on the processor ARM® Cortex®-A35 core technology. The integrated high performance graphics supports applications with high display requirements. Full access to all signal pins guarantees a very flexible usage and a cost-efficient project development.
For various requirements three CPU variants with a different performance and features are available. With a Dual / Quad-Core ARM Cortex™ A35 core and a clock rate up to 4x 1,2 GHz the module provides a balanced ratio between high performance and power dissipation.

Starterkit STK8Xx4 set

The core of the STKa8Xx4 set is the TQMa8Xx4 module with a i.MX8X Cortex A35 CPU. The components contained in the starter kit constitute a modular system enabling you to develop your own product ideas. Development of graphic interfaces can be started immediately using a TQ display kit which is adjusted for a starter kit. To develop your own hardware you can use the certified and qualified circuit components of the starter kit in your own designs.
