MCF51MM256VLK 概要
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripherals into one device. In the embedded-control hierarchy, the MCF51MM256VLK is a 32-bit MCU based on the ColdFire V1 core, a RISC processor architecture. Its combination of communication interfaces, precision measurement resources, and relatively substantial flash memory allows designers to consolidate functions that might otherwise require multiple discrete components.
Verified product information identifies 256 KB of flash memory organized as 256K x 8, a 50 MHz operating frequency, 47 I/O lines, and an 80-pin LQFP package. The verified connectivity list includes CANbus, EBI/EMI, I²C, SCI, SPI, and USB OTG. PWM, low-voltage detection, and watchdog-timer functions support motor, power, and industrial-control designs. The manufacturer describes the family as providing ultra-low-power operation, USB connectivity, graphic-display support, and high measurement accuracy.
The ColdFire V1 architecture gives the MCU a 32-bit processing path for embedded control, while the peripheral mix supports mixed-signal products and connected equipment. USB OTG can simplify direct host or device connectivity, while CANbus supports industrial networking. Serial interfaces provide expansion paths for displays, sensors, data converters, and communications modules. Because detailed electrical limits are not exposed in the supplied search data, design engineers should use the manufacturer data sheet and reference manual for voltage, timing, pin-level, and peripheral configuration details.
Typical applications include handheld metering equipment, medical products, industrial control panels, USB-connected instruments, CAN-based nodes, display controllers, and precision analog measurement systems. The part is particularly relevant where a 32-bit MCU, substantial flash storage, USB, and serial connectivity are needed together in one package. Its 80-pin LQFP also exposes more I/O than a small leadless MCU, which can simplify peripheral connection in a conventional through-hole assembly process.
The principal design consideration is lifecycle planning. The NXP product page labels MCF51MM256VLK as End of Life, so new production designs should confirm replacement recommendations with NXP rather than assuming long-term availability. Existing designs should verify the exact package pinout, voltage requirements, clock configuration, memory programming method, and USB implementation against the official documentation before layout or firmware changes.
This page combines the verified product identity, package, memory, core, interface, and lifecycle information with practical sourcing guidance. It is intended to help engineers evaluate the MCU quickly while preserving the distinction between verified facts and details that still require direct review of the manufacturer documentation.

Handheld Metering Devices
The MCF51MM256VLK fits handheld metering products because it combines a 32-bit ColdFire V1 processor, 50 MHz operation, 256 KB of flash memory, and precision-oriented analog features in one MCU. Its 47 I/O lines can connect sensors, display controls, buttons, and communication circuits while the integrated PWM and watchdog support responsive control behavior. The 80-pin LQFP package provides a practical pin count for a mixed-signal instrument rather than forcing multiple external interface ICs. Verify the complete ADC, timer, clock, and electrical specifications in the manufacturer data sheet before selecting input ranges or sampling rates. End-of-Life status also means new handheld platforms should confirm NXP replacement guidance before committing the design.
おすすめ
Medical and Precision Measurement Equipment
The MCF51MM256VLK is relevant to medical and precision measurement products because NXP describes the MCF51MM family as offering high measurement accuracy and identifies medical applications as a target use case. Its 32-bit ColdFire V1 core can process control logic and measurement data, while 256 KB of flash stores application firmware and calibration-related code. The available I²C, SCI, SPI, USB OTG, and CANbus interfaces support sensors, converters, laboratory interfaces, and service communications. The system designer must independently verify analog accuracy, noise, reference requirements, safety-related architecture, and operating limits because those parameters are not present in the supplied snippets.
おすすめ
USB-Connected Embedded Products
For USB-connected embedded products, the MCF51MM256VLK provides a 32-bit control core, 256 KB flash, and verified USB OTG connectivity in an 80-pin LQFP package. USB can reduce the need for a separate host controller when the firmware, connector, protection network, and power requirements are appropriately designed. The MCU also retains I²C, SCI, SPI, CANbus, and EBI/EMI options for local peripherals and industrial communication. Designers should confirm USB electrical characteristics, supported device or host roles, firmware support, clock requirements, and connector implementation from the manufacturer documentation. Because the part is End of Life, a new USB product should compare lifecycle-supported alternatives rather than assume long-term sourcing.
おすすめ
CAN-Based Industrial Control Nodes
The MCF51MM256VLK is suitable for CAN-connected industrial control nodes because the verified feature list includes CANbus, a 32-bit ColdFire V1 core, 50 MHz operation, PWM, watchdog timing, and 47 I/O lines. It can coordinate actuators, inputs, status indicators, and local service interfaces while retaining USB OTG for configuration or data transfer. A practical design still requires an appropriate CAN transceiver, protection network, termination strategy, bus timing configuration, and fault-safe shutdown behavior. The MCU’s flash capacity of 256 KB provides room for protocol, control, diagnostics, and application code, but RAM and detailed timing resources are not verified in the supplied data and must be checked before final firmware planning.
おすすめ
Graphic Display and User-Interface Controllers
The MCF51MM256VLK can serve as the control MCU in a display-oriented embedded product when the application needs a 32-bit processor, 256 KB flash, and multiple serial or bus interfaces. NXP describes the MCF51MM family as supporting graphic displays, while the verified connectivity list includes SPI, I²C, SCI, USB OTG, and EBI/EMI. These interfaces can connect display controllers, touch inputs, storage, configuration chips, and host-side service connections. The exact display controller compatibility, external memory requirements, timing, and electrical levels are not provided in the supplied snippets, so the designer should validate them against the reference manual and selected display hardware. End-of-Life status makes software and hardware migration planning especially important.
おすすめ
Low-Power Embedded Instruments
The MCF51MM256VLK fits low-power embedded instruments because the verified NXP product information specifically describes ultra-low-power operation as a family feature. The 32-bit ColdFire V1 core can provide efficient control processing, while low-voltage detection and watchdog functions support safe battery or supervised-power operation. The 256 KB flash capacity allows compact firmware and parameter storage, and the 47 I/O lines provide connections for sensors, indicators, and communication peripherals. Actual current consumption, sleep modes, wake-up sources, analog accuracy, and operating voltage were not included in the supplied data and must be measured or confirmed from the manufacturer documentation before a battery-life claim is made.

設計ノート
Verify the complete supply-voltage and absolute-maximum limits in the manufacturer data sheet before connecting external sensors, transceivers, or USB circuitry. The verified search data identifies a 3 V part but does not provide detailed input-voltage tolerances, regulator sequencing, or USB bus-power limits. Treat the 3 V label as a device-level identity specification, not as permission to apply 5 V signals directly; use level translation where required.
Reserve the 80-pin LQFP footprint and verify every pin assignment against the official package drawing before routing. Separate USB and high-speed communication traces from sensitive analog and measurement paths, provide the recommended decoupling architecture, and keep external transceiver and protection components close to their associated pins. Because the supplied data does not include the complete pinout, do not infer pin numbers from distributor descriptions.
Do not treat the MCF51MM256VLK as a current active MCU without confirming NXP lifecycle and replacement guidance. For an existing product, validate the installed part markings, package, flash size, clock configuration, bootloader, USB role, and firmware image before substituting inventory. A distributor’s “ships today” statement does not guarantee long-term supply, authenticity, or that an alternative source has identical revision behavior.
Plan USB, SPI, SCI, and CANbus interfaces according to the electrical and timing requirements in the official documentation. USB requires controlled impedance, suitable return paths, connector protection, and proper transceiver or on-chip connectivity implementation; CANbus normally requires an external transceiver and carefully selected termination and protection. These implementation details are not fully exposed in the supplied snippets, so use the manufacturer reference manual as the controlling source.
コンプライアンス情報
The supplied verified results do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. The NXP page identifies the product as End of Life, but that lifecycle label is not a compliance certification.
