JTAG Boundary-Scan I/O Modules

The Corelis family of SCANIO™ modules turn any IEEE standard 1149.1 boundary-scan controller into a powerful digital boundary-scan tester. The SCANIO family of products use boundary-scan gate arrays to add control and visibility to connectors, traces, and logic that can not be tested using traditional boundary-scan techniques.

The SCANIO products, when combined with a boundary-scan controller, operate as a traditional “bed-of-nails” tester except access to the stimulus and response I/O’s is achieved via boundary-scan.

335 238 ScanIO 300LV 300x213 - JTAG Boundary-Scan I/O Modules


High-Performance Boundary-Scan Digital I/O Module
  • High-performance, high pin-count boundary-scan I/O module.
  • Up to 300 single-ended or 150 differential individually controlled boundary-scan controllable digital I/O lines per module.
  • JTAG and digital I/O port voltages are configurable from 1.25V to 3.3V in 15 increments, or as LVDS logic (I/O ports only).
  • Each group of 50 I/Os can be bypassed to optimize scan time.
  • Includes BSDL files for integrating the ScanIO-300LV with UUTs.
  • TAP output port for single-chain configurations—one JTAG port can control the ScanIO and the UUT.
