XJIO Board
The XJIO board is an expansion unit that enables you to improve the test coverage for a Unit Under Test (UUT) by verifying connectivity right through to the external connections. It integrates with your XJTAG test system to provide access to otherwise inaccessible areas of your circuit.
With the digital and analogue I/O pins on the board, you can improve fault isolation, verify power rail levels, and dispense with costly custom test jigs – even for non-JTAG boards.
Key Benefits
Increase analogue and digital test coverage
Reduce your debug time by enhancing fault isolation
Help reduce the cost and complexity of your custom test jigs
Reach and test parts of your circuit with no JTAG access

- On-board 8 channel ADC and DAC, controlled using JTAG
- Fully expandable to meet your needs
- Switches and LEDs for user interaction
- ‘Black box’ testing for non-JTAG circuitry
- Reusable, replacing costly custom test jigs
- Standard IDC connectors
- 12V power supply
- Optional RS232 / UART
Digital I/O
With 208 bidirectional digital I/O pins, the XJIO board has been developed for maximum connectivity. The I/O pins are all 5V tolerant. The default logic level is 3.3V, however you can re-configure the I/O, in blocks of 16 pins, to use any user-generated voltage between 1.8V and 3.3V.
Analogue Testing
The XJIO board has 16 analogue I/O pins (8 inputs and 8 outputs), all controllable via the JTAG interface. The on-board 3.3V ADC devices enable basic analogue measurements – e.g. testing whether a power rail is within limits. The 3.3V DACs allows for UUT analogue inputs to be stimulated, improving test coverage of the target board.
Expandable
If more I/O is required, XJIO boards can be daisy-chained together via the reconfigurable external JTAG connector to reach the required density. All the connectors on the XJIO board are standard IDC, for economical and efficient cable assemblies.
Power Supplies
The XJIO board is designed to be powered from a 12 V supply and has a standard barrel-type connector.
User Interaction
The switches and LEDs enable additional test control, allowing you to develop a complete and repeatable test solution.
Compatibility
You can use the XJIO board with any of XJTAG’s JTAG controllers and the whole XJTAG software product range.
