MK51DX128CMC7 概要

The NXP Semiconductors MK51DX128CMC7 is a 32-bit Arm Cortex-M4 microcontroller operating at 72 MHz, with 128 KB of flash memory, 32 KB of SRAM, 61 I/O, USB connectivity, and high-precision analog integration in a 121-MAPBGA package measuring 8 x 8 mm. The Kinetis K51 device combines a segment LCD interface, USB, serial interfaces, DMA, and measurement-oriented analog peripherals for embedded instrumentation.

What is a Kinetis K51 microcontroller? It is a 32-bit embedded microcontroller in NXP's Kinetis portfolio, built around the Arm Cortex-M4 processor core. The MK51DX128CMC7 belongs to the Kinetis K51 measurement MCU family, which targets compact industrial, medical, consumer, and test equipment designs requiring local analog measurement, human-machine interfaces, and USB connectivity. It sits within the hierarchy of microcontroller, embedded processor, semiconductor, and electronic component.

Key verified features include a 72 MHz processor clock, 128 KB (128K x 8) program flash, 32 KB SRAM, 61 I/O, and an 8 x 8 mm 121-MAPBGA package. Listed connectivity includes I2C, IrDA, SPI, UART/USART, USB, and USB OTG. Listed peripherals include DMA, I2S, low-voltage detection, power-on reset, PWM, and a watchdog timer. These resources support simultaneous sensor acquisition, communications, display control, and control-loop processing.

The device architecture centers on a 32-bit Arm Cortex-M4 core with DSP-capable signal processing. Its high-precision analog integration makes it appropriate for measurement systems, while segment LCD support enables compact local user interfaces without requiring a separate display controller. USB and multiple serial interfaces provide paths for host connectivity, sensor networking, data logging, and configuration. Firmware should use the manufacturer's device configuration, pin multiplexing, clock, analog, and low-power guidance for the exact package variant.

Typical applications include digital multimeters, temperature-measurement instruments, medical monitoring equipment, industrial panel meters, USB-connected test tools, and compact data-acquisition systems. In these systems, the MCU can collect sensor inputs, run calibration and filtering, drive a segment display, communicate with an upstream host, and supervise power or peripheral activity.

The primary design consideration is BGA layout and firmware portability. A 121-MAPBGA package requires fine-pitch assembly capability and careful escape routing; the selected PCB stack-up, land pattern, solder-mask design, and assembly process must follow NXP guidance. Validate signal integrity for USB and serial interfaces and budget CPU and DMA bandwidth for simultaneous measurement and display updates.

This product page combines verified distributor specifications, manufacturer status, package information, and practical design guidance. It distinguishes confirmed values from parameters not supplied in the retrieved sources and avoids inventing pin assignments, electrical limits, or drop-in replacements that were not explicitly verified.

主な用途

MK51DX128CMC7 の用途: 6 件s: Digital Multimeter and Panel Meter, USB-Connected Test and Measurement Tool, Industrial Sensor Acquisition, Medical Monitoring Instrument, Portable Environmental Monitor, Battery-Powered Data Logger.

🔧

Digital Multimeter and Panel Meter

The MK51DX128CMC7 fits handheld meters and panel instruments because its 72 MHz Arm Cortex-M4 core can process measurements while the device integrates high-precision analog functions, segment LCD support, and USB connectivity. The 128 KB flash and 32 KB SRAM provide room for measurement algorithms, calibration data, display routines, and USB firmware. Use the MCU to acquire sensor inputs, apply filtering or compensation, update a local display, and send results to a host. The principal tradeoff is the 121-MAPBGA layout, which requires fine-pitch PCB assembly capability and careful analog-versus-digital partitioning.

⚡

USB-Connected Test and Measurement Tool

The MK51DX128CMC7 is appropriate for a USB-connected test instrument because the verified feature list includes USB, USB OTG, a 72 MHz Cortex-M4 processor, 128 KB flash, and 32 KB SRAM. Firmware can acquire measurements, format results, expose a USB interface, and update a local display without a separate communications processor. The package integrates 61 I/O into an 8 x 8 mm 121-MAPBGA footprint, useful for compact portable equipment, but USB routing, connector protection, ground planning, and firmware testing must follow the manufacturer's electrical and layout guidance.

🏭

Industrial Sensor Acquisition

The MK51DX128CMC7 can serve as the central controller in an industrial sensor-acquisition module because it combines high-precision analog integration with DMA, 32 KB SRAM, and multiple serial interfaces including I2C, SPI, UART/USART, and IrDA. The 72 MHz Cortex-M4 core supports signal conditioning, filtering, status logic, and communication while limiting external component count. DMA can move sampled data with less CPU intervention, but channel selection, accuracy, reference voltage, acquisition timing, and electrical limits must be confirmed from the exact NXP datasheet. Industrial qualification also requires reviewing the specified temperature grade and environmental requirements.

💊

Medical Monitoring Instrument

The MK51DX128CMC7 can support compact medical or laboratory monitoring equipment when its verified high-precision analog integration, 72 MHz processing speed, USB connectivity, and segment LCD capability match the measurement architecture. The MCU can process sensor data, maintain calibration information, drive a clinician-facing display, and log or transmit results. Its industrial temperature grade should not be treated as medical certification; designers must separately evaluate electrical safety, isolation, risk management, software validation, and applicable regulatory requirements. The fine-pitch 121-MAPBGA also affects assembly yield and serviceability.

🧩

Portable Environmental Monitor

The MK51DX128CMC7 is a candidate for a portable environmental monitor because the verified sources identify low-power-oriented Kinetis family positioning, USB or USB OTG, segment LCD support, and serial connectivity. A product can use the MCU to acquire temperature, humidity, gas, or motion-related sensor data, present readings locally, and periodically synchronize with a computer or charger interface. The 72 MHz Cortex-M4 core leaves processing headroom for filtering and compensation, while 128 KB flash and 32 KB SRAM support moderate application code and buffering. Battery life, sleep modes, ADC limits, and regulator requirements remain datasheet-dependent design checks.

🔋

Battery-Powered Data Logger

MK51DX128CMC7 can be evaluated for a battery-powered data logger when USB connectivity, serial sensor interfaces, DMA, and local display support are valuable. The 72 MHz Cortex-M4 core can manage timestamped acquisition and buffering, while 128 KB flash and 32 KB SRAM handle moderate workloads. A low-power design should use the exact Kinetis low-power modes and retention rules from the manufacturer documentation, then confirm the effect of USB, LCD, analog conversion, and memory activity on current draw. The 121-MAPBGA package may increase board complexity but supports compact instrumentation when the manufacturing process is capable.

What are the key specifications of MK51DX128CMC7 that engineers should know?
The MK51DX128CMC7 is a 72 MHz, 32-bit Arm Cortex-M4 microcontroller with 128 KB flash, 32 KB SRAM, 61 I/O, USB, and multiple serial interfaces in an 8 x 8 mm 121-MAPBGA package. According to the NXP product page and DigiKey listing, it belongs to the Kinetis K51 measurement-MCU family and includes segment LCD support and high-precision analog integration. These features make it suited to measurement instruments with local displays, sensor acquisition, USB data transfer, and embedded control functions.
Where to download the MK51DX128CMC7 datasheet PDF?
The official MK51DX128CMC7 datasheet and product resources are available from the NXP product page at https://www.nxp.com/part/MK51DX128CMC7. The retrieved manufacturer result identifies the device as active and provides a Data Sheet link. Use that manufacturer source for the definitive pin assignments, electrical limits, package drawings, memory map, clock requirements, and package-specific land pattern; those details were not included in the supplied search snippets.
Where can I find the MK51DX128CMC7 pinout?
The MK51DX128CMC7 pinout should be obtained from the manufacturer datasheet and package drawing for the 121-MAPBGA, not inferred from distributor images or generic BGA libraries. The verified listing confirms a 121-MAPBGA package measuring 8 x 8 mm and 61 I/O, but it does not provide the complete numbered ball map. Consequently, a complete pinout cannot be reproduced reliably here; consult NXP documentation before routing power, ground, analog inputs, USB, serial signals, and segment LCD connections.
What is the price of MK51DX128CMC7?
MK51DX128CMC7 is listed from $9.5371 at eBee in the retrieved web data as of 2026-10-20. Heisener separately lists a unit price of $9.8188 and states that the part is for reference, while distributor pricing and stock can change. The displayed tiers retain the verified $9.5371 value without extrapolating unverified volume discounts. For procurement, compare the NXP authorized-distributor listing, stock, and landed cost before ordering.
Is MK51DX128CMC7 in stock?
MK51DX128CMC7 is reported in stock by Heisener, which lists 5,168 pieces, and DigiKey states that the part ships today. However, stock quantities are time-sensitive and the NXP page identifies the device as active without providing a guaranteed allocation. Availability should therefore be checked with the selected distributor when placing an order; the Schema.org offer uses BackOrder conservatively because explicit XAIPART inventory was not supplied.
What is the lead time for MK51DX128CMC7?
The verified Heisener listing gives an estimated delivery interval of March 25 through March 30, but it does not state a universal lead time or identify the order date. NXP lists the product as active, which supports current sourcing, while DigiKey states that shipments can begin immediately. Because distributor schedules vary by quantity and stock, request a firm quotation and scheduled delivery date rather than treating the displayed estimate as a production commitment.
Where to buy MK51DX128CMC7 online?
MK51DX128CMC7 can be ordered through the NXP product page, DigiKey Marketplace, Mouser, and listed regional distributors. The retrieved data includes DigiKey stock language, a Mouser product listing, and eBee pricing from $9.5371 as of 2026-10-20. Before purchasing, confirm authorized-source status, ball-grid-array handling requirements, date codes, and whether the 121-MAPBGA package can be assembled by the selected PCB fabricator and contract manufacturer.
What can replace MK51DX128CMC7?
No verified direct drop-in replacement was found for MK51DX128CMC7 in the supplied cross-reference results. A valid replacement must match the 121-MAPBGA ball pattern, pin functions, power architecture, Arm Cortex-M4 software requirements, 128 KB flash, 32 KB SRAM, and connected peripherals. Generic cross-reference tools may find similar devices, but those results do not prove drop-in compatibility. Treat any candidate as a redesign until NXP documents and manufacturer pin data confirm every board-level function.
Is MK51DX128CMC7 the same as MK50DX128CMC7?
No. The comparison result identifies MK51DX128CMC7 and MK50DX128CMC7 as distinct NXP Kinetis K50-series MCUs, but it does not provide a pin-compatible equivalence statement. Both are identified broadly as 128K Flex devices, yet family naming alone does not establish identical memory maps, analog peripherals, pin multiplexing, clocking, or software support. Use the MK51DX128CMC7 datasheet for design decisions and treat MK50DX128CMC7 as an unverified comparison candidate rather than a drop-in substitute.
MK51DX128CMC7 vs MK50DX128CMC7: which is better for a measurement instrument?
MK51DX128CMC7 is the better-documented choice for the stated measurement design because NXP identifies it as a Kinetis K51 72 MHz measurement MCU with segment LCD, USB, and high-precision analog integration. The supplied comparison snippet does not establish the same feature set for MK50DX128CMC7, so it cannot support a complete feature comparison. Choose MK50DX128CMC7 only after checking its manufacturer documentation, BGA pin map, ADC performance, LCD interface, USB compatibility, and firmware migration requirements.
When should I choose MK51DX128CMC7 instead of another 72 MHz microcontroller?
Choose MK51DX128CMC7 when a compact measurement instrument benefits from one MCU combining a 72 MHz Arm Cortex-M4 core, 128 KB flash, 32 KB SRAM, segment LCD control, USB, serial connectivity, and analog peripherals. It is less attractive when your board cannot accommodate a 121-MAPBGA layout, when peripheral requirements are incompatible, or when legacy software depends on a different memory map or driver family. The verified sources do not establish a verified drop-in alternative, so migration remains a design decision rather than a substitution.
Is MK51DX128CMC7 suitable for USB-connected measurement equipment?
MK51DX128CMC7 is suitable for USB-connected measurement equipment because the verified listings identify USB and USB OTG connectivity, a 72 MHz Cortex-M4 core, high-precision analog integration, and a 121-MAPBGA package. The MCU can coordinate sensor acquisition, control functions, local display updates, and host communication in one device. USB implementation still requires the correct package pins, transceiver components, impedance-controlled routing, firmware support, and compliance testing described in the NXP documentation.
Does MK51DX128CMC7 support segment LCD and USB on the same device?
Yes, the verified product information identifies both segment LCD support and USB or USB OTG connectivity in the same MK51DX128CMC7 device. This combination is useful in handheld meters, panel instruments, and compact laboratory tools where measured values must be displayed locally while data is also sent to a computer or service interface. Exact simultaneous-use limitations, display segment count, pin multiplexing, and USB electrical requirements must be confirmed in the manufacturer datasheet.
How much flash and SRAM does MK51DX128CMC7 provide?
MK51DX128CMC7 provides 128 KB of flash memory, represented by DigiKey as 128K x 8, and the family description specifies 32 KB of SRAM. These resources support firmware, calibration tables, USB descriptors, display code, communication stacks, and measurement buffering. The retrieved snippets do not specify external memory interfaces or detailed memory-map restrictions, so final memory budgeting should use the official datasheet and linker configuration for this exact MPN.
What package and PCB layout challenges does MK51DX128CMC7 present?
MK51DX128CMC7 uses a 121-MAPBGA package measuring 8 x 8 mm, so its main layout challenge is fine-pitch ball-grid-array assembly rather than a leaded through-hole connection. Place decoupling and required power-network structures according to NXP guidance, escape balls through the PCB stack-up, and validate USB and other high-speed or sensitive analog routes. The supplied data does not include the exact land pattern, so the manufacturer package drawing and assembly process requirements are mandatory before layout release.

エンジニアリング参考データ: MK51DX128CMC7 — 比較、設計ガイダンス、コンプライアンス情報。

選定ガイド

Choose MK51DX128CMC7 for a compact measurement product that needs a 72 MHz Arm Cortex-M4 core, 128 KB flash, 32 KB SRAM, USB, segment LCD support, and integrated high-precision analog functions. The device is particularly attractive for handheld meters, industrial panel instruments, test equipment, and portable data loggers where one MCU must coordinate acquisition, display, communications, and control. Choose another device only after checking the exact pinout, memory map, peripherals, voltage requirements, and software support against the board. The supplied sources do not verify a direct drop-in replacement, so any substitute must be treated as a redesign until package and pin compatibility are documented. In particular, do not assume that the similarly named MK50DX128CMC7 is interchangeable solely because both are identified as 128K Flex Kinetis devices.

設計ノート

Design the PCB around the exact 121-MAPBGA land pattern supplied by NXP. The verified package is 8 x 8 mm, so escape routing, via placement, solder-mask definition, and pad finish must follow the manufacturer assembly and land-pattern guidance. Do not derive the layout from a generic BGA footprint. Confirm that the assembly house supports the ball pitch, package dimensions, thermal requirements, and inspection coverage before releasing the board.

Separate analog, digital, USB, and display-related routing where practical. Keep sensor inputs away from switching nodes and high-current return paths, use a continuous ground reference, and place decoupling structures near the corresponding device pins according to the NXP recommendation. The retrieved data confirms high-precision analog integration and USB/USB OTG, but it does not provide the complete pin map or pin-multiplexing matrix; verify those details before assigning every signal.

Plan the supply rails and decoupling before schematic freeze. The supplied data confirms a 72 MHz Cortex-M4 MCU with USB, segment LCD, DMA, and serial interfaces but does not state the operating-voltage range, current limits, regulator requirements, or exact power-pin grouping. Use the official datasheet for recommended supply voltage, sequencing, decoupling values, and absolute maximum ratings. Estimated power consumption should not be used for production sizing until those values are confirmed.
