SCANSTA101SMX/NOPB

Specialized Overview

The SCANSTA101SMX/NOPB is a specialized interface integrated circuit manufactured by Texas Instruments, designed for low-voltage IEEE 1149.1 system test access applications. It supports the Boundary Scan protocol to facilitate digital interconnect testing and board-level diagnostics. The device operates at a fixed supply voltage of 3.3 V with a typical operating supply current of 250 uA. It is rated for an extended industrial temperature range from -40°C to +85°C. The component is housed in an nFBGA-49 package suitable for surface-mount technology (SMD/SMT) installation. This specific suffix indicates reel packaging, distinguishing it from tray-packaged variants within the same product family.

Specialized Feature Summary

• Supports IEEE 1149.1 standard for boundary scan testing
• Low voltage operation optimized for 3.3 V systems
• Surface-mount compatible nFBGA-49 package design

Specialized Applications

• Digital interconnect testing on printed circuit boards
• Boundary scan architecture implementation
• System-level test access port integration

Specialized Procurement Notes

Verify the exact ordering suffix when sourcing this component. The 'SMX' designation specifically denotes reel packaging, which differs from the 'SM' variant that uses tray packaging. Confirming the correct suffix ensures compatibility with automated pick-and-place equipment and prevents handling errors during assembly. Always cross-reference the manufacturer part number against official distributor catalogs to ensure authenticity and correct package type identification before placing orders.

Specialized Selection Notes

Select this component when designing systems requiring standardized IEEE 1149.1 test access ports. Ensure the design accommodates the 3.3 V power rail and the thermal requirements for the -40°C to +85°C operating range. The nFBGA-49 package footprint must be matched precisely in the PCB layout. Consider the moisture sensitivity level indicated in the datasheet to determine proper storage and reflow soldering profiles during manufacturing.

Specialized Part Context

This part belongs to the SCANSTA101 series of specialized interface ICs from Texas Instruments. It serves as a dedicated solution for implementing boundary scan capabilities in complex electronic assemblies. The series provides standardized test access mechanisms compliant with industry protocols, enabling efficient verification of signal integrity between components on the same substrate without requiring physical probe access.

Specialized Replacement Considerations

The SCANSTA101SM/NOPB is a functional equivalent with identical electrical specifications but utilizes tray packaging instead of reels. Verify pinout compatibility and package dimensions before substitution. No other direct substitutes are publicly confirmed for this specific model.
