SCANSTA111MT/NOPB

Specialized Overview

The SCANSTA111MT/NOPB is an enhanced SCAN bridge multidrop addressable IEEE 1149.1 (JTAG) port controller manufactured by Texas Instruments. It facilitates the connection of multiple JTAG-compliant devices in a multidrop configuration, allowing access to various boundary scan chains through a single interface. The component operates within an industrial temperature range of -40°C to +85°C and is housed in a 49-pin NFBGA package.

Specialized Feature Summary

• Supports multidrop addressing for multiple JTAG ports
• Enhanced SCAN bridge functionality for efficient data routing
• Compliance with IEEE 1149.1 standards

Specialized Applications

• Boundary scan testing systems
• Multidrop JTAG network configurations
• System-level debugging and verification

Specialized Procurement Notes

Verify the specific suffix MT indicates the tape-and-reel packaging variant distinct from tray options. Confirm the NOPB designation ensures lead-free compliance and RoHS adherence. Cross-reference the manufacturer's latest datasheet to ensure the part number matches current production status and availability channels.

Specialized Selection Notes

Select this component when designing systems requiring a single JTAG interface to control multiple downstream devices in a multidrop topology. Ensure the design supports the required voltage levels and signal integrity for the NFBGA package. Verify that the target application benefits from the enhanced SCAN bridge features over standard multiplexers.

Specialized Part Context

This device belongs to the SCANSTA family of JTAG interface controllers. It serves as a specialized interface solution for complex embedded systems where space and pin count are constrained. The NFBGA package provides a compact footprint suitable for high-density PCB layouts.

Specialized Replacement Considerations

The SCANSTA111SMX/NOPB is a documented alternative offering similar functionality in a different package format. Evaluate pin compatibility and thermal requirements before substitution.
