1.1 Features and Overview

The BIST-XPRO enables selective introduction of failures, such as shorts or open, to the feeding lines of the sensor. The real time detection of these failures is an essential part of these safety-related applications:

• ISO26262 (ASIL) for Automotive
• IEC60730 for Appliances
• IEC 61508 (SIL) for Industrial
• IEC 62304 for Medical

The board connects between compatible XPRO MCU boards or to Curiosity Nano MCU boards via the Curiosity Nano Touch Adapter and extension sensor boards, such as the QT7-XPRO.

The BIST-XPRO enables quick testing of the BIST and Power-up Self-Test (POST) routines for their effectiveness to test common pin failures:

• Pin short to V_DD
• Pin short to V_SS / GND
• Pin short to another pin
• Pin open (e.g. broken sensor feeding line)
