SCANSTA111SM/NOPB

Specialized Overview

The SCANSTA111SM/NOPB is an enhanced scan bridge multidrop addressable interface component manufactured by Texas Instruments. It supports the IEEE 1149.1 (JTAG) boundary scan protocol for system-level testing and debugging. The device operates within a supply voltage range of 3 V to 3.6 V, with a maximum operating voltage of 3.6 V and a typical operating current of 1.65 mA. It functions reliably across an industrial temperature range from -40°C to +85°C. The component is housed in a 49-pin nFBGA package suitable for surface mount technology (SMD/SMT). It exhibits moisture sensitivity, requiring appropriate handling during assembly.

Specialized Procurement Notes

Verify the specific ordering suffix and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the component meets all environmental and packaging requirements for your manufacturing process. Ensure proper handling procedures are followed due to moisture sensitivity classification. Cross-reference part numbers carefully to avoid confusion between similar variants in the SCANSTA family.

Specialized Selection Notes

Select this component when designing systems requiring multidrop JTAG connectivity and boundary scan capabilities. Ensure the design accommodates the 3 V to 3.6 V supply voltage range and the nFBGA-49 package footprint. Consider the thermal characteristics and operating temperature limits (-40°C to +85°C) relative to the intended application environment. Verify compatibility with existing test infrastructure supporting IEEE 1149.1 standards.
