MAC7111MPV50-FR 概要
A microcontroller is a semiconductor that integrates a processor core, nonvolatile program memory, data memory, peripheral controllers, and interface logic into one embedded-computing device. Within the hierarchy of semiconductor, integrated circuit, embedded processor, and microcontroller, the MAC7111MPV50-FR belongs to the ARM7TDMI-S product class. That processor organization is intended for embedded control rather than a desktop operating system, making the device relevant to automotive electronics, industrial controllers, communication equipment, and real-time control products.
The verified product information establishes a 50 MHz operating frequency, 512 KB flash, 32-bit single-core processing, and 144-LQFP packaging. One search result also characterizes the part as automotive-grade, while the family hardware document contains electrical specifications, pin assignments, and package diagrams. Flash capacity provides room for embedded code and constants, but the supplied excerpts do not expose RAM size, peripheral inventory, memory-map details, or electrical limits; those values must be verified in the full manufacturer hardware document before schematic or firmware work.
Engineers should treat the 144-pin LQFP as a substantial mixed-signal and digital controller package. The 20 mm by 20 mm footprint requires adequate routing area, exposed escape access, and careful assembly planning. Its gull-wing leads are more visually inspectable than fine-pitch BGA interconnects, but they still require controlled fanout, solder mask definition, and thermal verification. The family document's pin assignments should govern connector, ground, supply, clock, and peripheral routing.
Typical engineering uses include automotive body and communication modules, industrial automation equipment, networked embedded controllers, and compact real-time systems. Suitability depends on validating the exact peripheral set, memory resources, electrical characteristics, temperature range, and software constraints. No assumption should be made merely because another 50 MHz controller has a similar headline specification; software architecture and peripheral compatibility are as important as clock speed.
A legacy or unavailable MCU replacement must be treated as a risk-management decision. Confirm package dimensions, pin assignments, power behavior, peripheral multiplexing, clock topology, memory, and software binary compatibility before substituting. This page combines verified distributor identification, package data, sourcing information, and explicit uncertainty markers rather than inferring unsupported specifications.
The practical information gain here is the separation of verified facts from missing engineering data: the 50 MHz ARM7TDMI-S core, 512 KB flash, and 144-LQFP footprint are usable selection facts, while unspecified RAM, pins, electrical limits, and lifecycle status remain explicit validation items.

主な用途
MAC7111MPV50-FR の用途: 6 件s: Legacy Automotive Control Module, Industrial Automation Controller, Real-Time Communication Equipment, Compact Embedded System, Instrumentation Control Platform, Obsolete-Production Recovery.
Legacy Automotive Control Module
MAC7111MPV50-FR fits a legacy automotive-control design that already uses the 144-LQFP footprint and ARM7TDMI-S software environment. Its verified 50 MHz single-core processor provides deterministic embedded-compute capability, while 512 KB flash supports a qualified control program and constants. The Partstack record identifies automotive temperature grade, but deployment still requires review of the original operating-temperature range, electrical limits, qualification records, and diagnostic requirements. Maintaining the established package can avoid a board redesign, yet scarce inventory and an unclear lifecycle status make traceability and long-term sourcing critical.
おすすめ
Industrial Automation Controller
MAC7111MPV50-FR is applicable to an existing industrial controller where a 50 MHz ARM7TDMI-S core and 512 KB flash must be retained for software continuity. Its 144-LQFP package provides many external connections for sensors, actuators, communications, and digital interfaces, although the exact multiplexed functions remain unverified in the supplied excerpts. For an operating industrial system, use the original hardware documentation to verify supply tolerances, environmental limits, clock stability, watchdog behavior, communications peripherals, and functional-safety assumptions. Obsolescence management should begin immediately because no qualified drop-in alternative was found.
おすすめ
Real-Time Communication Equipment
The 50 MHz ARM7TDMI-S processing core makes MAC7111MPV50-FR relevant to established communication equipment with deterministic control tasks, while 512 KB flash provides storage for protocol and application code. In an existing 144-LQFP board, retaining the device can preserve validated drivers and timing behavior. The supplied data does not identify Ethernet, CAN, serial, USB, or memory-interface capabilities, so none should be assumed. Interface selection must come from the family hardware document and the exact MCU variant; otherwise communications redesign and firmware requalification could become necessary.
おすすめ
Compact Embedded System
MAC7111MPV50-FR can serve as the central controller in a compact embedded system built around an existing 144-LQFP board. Its single-core 32-bit ARM7 architecture and 50 MHz clock are appropriate for coordinating real-time tasks, while 512 KB flash holds embedded code. The 20 mm by 20 mm package is not physically tiny, so enclosure and routing planning must accommodate 144 gull-wing leads and adequate copper escape. Confirm RAM, peripheral multiplexing, input thresholds, and clock requirements from the original documentation before transferring the design to a new production run.
おすすめ
Instrumentation Control Platform
MAC7111MPV50-FR is suitable for an established instrumentation-control platform where firmware compatibility matters more than adopting a newer processor. The 50 MHz ARM7TDMI-S core can execute measurement sequencing and supervisory logic, and the 144-terminal package offers extensive routing options. However, analog front-end compatibility cannot be inferred from digital-controller specifications. Verify ADC resources, timers, memory interfaces, signal tolerances, grounding, and clock accuracy against the full hardware document. If those characteristics match the installed design, avoiding a board change can substantially reduce requalification effort.
おすすめ
Obsolete-Production Recovery
MAC7111MPV50-FR is relevant to production recovery where an established product still depends on the original MCU and cannot tolerate redesign. Verified sourcing is limited: the public search reported 1.533 units and a starting price of $20.28 as of 2026-10-21, while the lifecycle state is unknown. Procurement should require original-part traceability, date-code and lot information, visual inspection, electrical testing, and documented functional equivalence. A zero-defect claim should be confirmed through an agreed test protocol, and samples must be validated in the finished product before broad deployment.

- Large established pin-count integration （vs Newer controllers with smaller packages)
設計ノート
Do not infer pin compatibility from the shared 50 MHz clock or ARM7 architecture. A valid replacement must first match the 144-LQFP terminal arrangement, 20 mm by 20 mm body, exposed pad or thermal requirements, supply pins, ground architecture, clocks, boot inputs, memory interfaces, and every multiplexed peripheral. The verified search returned no qualified replacement, so use the original family hardware document and existing board files as the authority.
Plan routing and assembly around 144 gull-wing leads on a 20 mm by 20 mm square package. Maintain the manufacturer-recommended land pattern, pad dimensions, solder-mask clearance, and paste volume; the verified sources identify the package but do not provide fabrication drawings. Place decoupling and grounding structures close to their assigned pins once the exact pinout is confirmed, and conduct assembly-capability checks because fine lead spacing can affect paste deposition and bridging.
Validate power sequencing, supply tolerance, input thresholds, output states during reset, and clock startup directly from the complete hardware document before schematic release. Those values are not present in the supplied excerpts and must not be estimated from the 50 MHz operating frequency. For an existing product, compare the incumbent and sourced MAC7111MPV50-FR electrically at startup, reset, brownout, idle, and operating conditions. Suspect or remarked inventory should be tested before it is approved for production.
Treat the $20.28 listing and 1.533-unit stock statement as retrieval-time market observations, not guaranteed procurement commitments. As of 2026-10-21, the evidence does not provide a formal lifecycle classification, traceable lot allocation, or a complete volume price curve. Request manufacturer traceability, date code, lot code, operating-temperature grade, package markings, refurbishment disclosure, return terms, and a written delivery estimate before allocating the devices to safety- or production-critical builds.
コンプライアンス情報
Partstack labels the device as automotive temperature grade, but the supplied evidence does not establish AEC-Q100 qualification or any current RoHS, REACH, lead-free, halogen-free, or conflict-minerals status.
