The 0.80 mm ball pitch on the 49-BGA is forgiving for a hand-assembly or rework station — a standard hot-air nozzle with a 10x10 mm aperture and a stencil thickness of 0.12 mm to 0.15 mm is adequate for prototyping or low-volume test-fixture builds. ## JTAG interface and test-equipment deployment The IEEE 1149.1 interface is the same JTAG port used by most FPGA, CPLD, and processor debug tools — the SCANSTA101SM acts as a bus master or access port controller in a boundary-scan chain, allowing a host controller to shift test vectors through the scan path of the board under test. This makes it a natural fit for automated test equipment (ATE), in-circuit test (ICT) fixtures, and diagnostic pods where the goal is to isolate opens, shorts, or stuck-at faults on dense BGA-based assemblies without physical probe access.","metaTitle":"TI SCANSTA101SM Boundary-Scan Controller, 49-BGA, Active","metaDescription":"Texas Instruments SCANSTA101SM IEEE 1149.1 test-access controller in 49-LFBGA.
