RAD-HARD Via Configurable Arrays

Military and aerospace applications must satisfy mission critical requirements for size, weight and power. And, many mil/aero environments demand solutions with significant radiation hardness to survive and provide high reliability long-term operation.

VCA
Military Applications

Triad combines silicon-proven analog and digital resources that are radiation hardened by design or process into via-configurable arrays (VCA) that can be configured with a single mask layer. The VCA approach provides designers with benefits that have been previously unobtainable with FPGAs and traditional full-custom mixed signal ASICs.

Triad’s VCA benefits include:

  • Prototyping in silicon during system development
  • Low cost design changes or product derivatives
  • Consolidation of digital and analog into an SoC
  • Power reduction of up to 90% vs. FPGA
  • IP Reuse – eliminate 3rd party IP issues
  • Production parts in < 4 weeks
  • Significant risk mitigation

Via Configurable Arrays

The base technology for VCAs was developed by ViASIC and has been in development for use in space applications since 2000. Triad adapted this technology to analog and the VCA was born. Now being used in high volume commercial applications, Triad recently introduced VCAs to the military and aerospace markets as the perfect solution to size, weight and power concerns. In partnership with Sandia National Labs, AFRL, MDA and MRDC, we are pleased to offer the following families of radiation tolerant product platforms:
