PAC5256QXST

Product Overview

PAC5256QXST is a PAC5xxx Power Application Controller motor-control SoC associated with Qorvo / Active-Semi. The device is cataloged under application-specific microcontrollers because its processing and peripheral resources are optimized for a defined control task rather than general-purpose MCU use.

Qualification of PAC5256QXST should compare the complete electrical and functional design: processor architecture, memory model, clock source, reset and start-up behavior, supply rails, interface levels, package pinout, programmed content and supported development tools. For legacy or application-specific silicon, an apparently similar controller may not accept the same firmware or reproduce cycle-level timing. Preserve the original binary, configuration data and board test procedure before approving a replacement.

Key Features

• Full part number: PAC5256QXST
• Manufacturer / historical brand: Qorvo / Active-Semi
• Device type: PAC5xxx Power Application Controller motor-control SoC
• Power Application Controller combining an embedded MCU with motor-control-oriented analog and power-driver resources
• PAC5210, PAC522x, PAC5232, PAC524xx, PAC525x and PAC527xx have different gate drivers, power stages and peripherals
• QF, QM, QX and related package tokens plus T, ST and SR shipment forms must match
• Motor type, supply voltage, current sensing, MOSFET selection, protection and control firmware require exact validation
• Qorvo and Active-Semi branding may both appear on lifecycle documentation
• Shipping suffix indicates tape-and-reel on families where the manufacturer defines T as the reel option; verify reel quantity separately

Applications

• Application-specific embedded control
• Original-platform maintenance and exact-part replacement

Application suitability should be confirmed against the original system requirements, including interface role, firmware revision, environmental range, package assembly process and any programmed or calibrated data. These examples describe realistic uses of the researched device family; they do not imply that every ordering suffix includes every optional peripheral or qualification grade.

Quality & Sourcing

Antrex Electronics can support sourcing review for PAC5256QXST, including verification of the complete ordering suffix, package, date code, packaging form and visible marking. Buyers should state the required quantity and whether blank, factory-programmed or customer-programmed material is acceptable. For programmable, secure or touch-controller devices, the firmware image, security provisioning state and customer option code can be as important as the silicon itself; Antrex Electronics does not assume that blank stock will reproduce an installed part. For obsolete or long-stored material, photos, label review, traceability checks, lead or ball inspection, solderability assessment and third-party electrical or X-ray testing can be arranged when project risk warrants them. Availability, date code and test scope remain subject to quotation and inspection.
