The VCA-6 is a via-configurable array (VCA) that contains over 1,000,000 ASIC gates, 96 op-amps and supporting analog resources.

The fully differential, wideband devices in this VCA enable the design of high speed, high resolution data converters, analog filters, and mixed-signal DSP solutions. VCA-6 provides the resources needed to sweep up an entire printed circuit board (PCB) containing  FPGAs, microcontrollers and surrounding analog ICs into a single integrated solution, thereby reducing the size, weight and power (SWAP) of the board-level implementation.

Like all of Triad’s configurable devices, VCA-6 uses patented via-only, single-mask configuration allowing design changes in weeks – not months, low development costs, reduced risk and support for any production volume.
