MCF51QU64VHS Overview
A microcontroller is a programmable semiconductor device that integrates a processor core, memory, and peripherals into one component. The ColdFire architecture provides a 32-bit instruction set for control and signal-processing tasks, while the MCF51Qx family combines Flash and configurable embedded EEPROM through Freescale FlexMemory technology. Its small package supports space-constrained products requiring mixed-signal or embedded control functionality.
Verified listings identify a ColdFire V1 core, 64 KB Flash organized as 64K x 8, 50 MHz operating frequency, and 44-MAPLGA construction. The NXP product-page excerpt also identifies a high-accuracy 16-bit ADC, configurable embedded EEPROM, ultra-low-power capabilities, and a 5 x 5 mm footprint. These features make the MCU suitable for industrial control, sensor acquisition, connected embedded equipment, and compact consumer products.
The MCF51Qx portfolio scales from 32 KB to 128 KB of Flash and uses a small package family for low-power designs. Compared with larger microcontrollers, the MCF51QU64VHS offers a compact 44-pin option and a direct 32-bit control platform. Exact RAM, voltage limits, ADC performance, timer resources, and pin-level functions were not included in the supplied verified data and should be checked in the manufacturer datasheet before design release.
Typical applications include industrial sensor nodes, motor and actuator control, instrumentation, building automation, and low-power embedded controllers. The 16-bit ADC is useful when analog inputs must be digitized close to the processing core, while the 50 MHz ColdFire V1 core supports responsive control logic. Engineers should confirm peripheral mappings, pin multiplexing, memory constraints, and electrical limits against the official documentation.
For a new PCB, place the MCU according to the manufacturer package drawing and preserve access to programming and debug signals. For an existing design, verify the MAPLGA land pattern, exposed-pad or thermal requirements, decoupling strategy, and pin multiplexing before substituting this device. The supplied distributor results identify the part as active, but inventory and price must be confirmed at the point of purchase.
This page consolidates the verified NXP family description, distributor specifications, package information, sourcing links, and design caveats for MCF51QU64VHS. It is intended to support initial component selection while separating confirmed data from parameters that still require datasheet confirmation.

MCF51QU64VHS square Pin Configuration Guide
Pin configuration for MCF51QU64VHS (square package). This digital IC includes GPIO, communication interfaces (UART, SPI, I2C), and power pins. Refer to the manufacturer datasheet for alternate pin functions and configuration options. Essential for embedded system design and PCB layout.
No detailed pinout data available for MCF51QU64VHS.
Refer to the datasheet for full pin configuration.
Typical Applications
MCF51QU64VHS is suitable for 6 applications: Industrial Sensor Nodes, Compact Data Acquisition Systems, Motor and Actuator Control, Building Automation Controllers, Instrumentation and Measurement Products, Low-Power Embedded Products.
Industrial Sensor Nodes
The MCF51QU64VHS fits compact sensor-node designs that need 32-bit control and local analog conversion without a large processor package. Its verified 50 MHz ColdFire V1 core can manage acquisition sequencing, filtering, and communication logic, while the high-accuracy 16-bit ADC provides a suitable interface for transducers. The 44-MAPLGA 5 x 5 mm package also helps reduce board area. Before committing, verify the exact ADC resolution behavior, input range, sampling timing, and pin multiplexing in the official datasheet.
Recommended
Compact Data Acquisition Systems
The MCF51QU64VHS is suitable for compact data-acquisition equipment where analog inputs must be digitized close to the control processor. The manufacturer description identifies a high-accuracy 16-bit ADC, and the verified 50 MHz ColdFire V1 core can support control of acquisition sequencing and local processing. Its small 5 x 5 mm MAPLGA package preserves board space in multi-channel or embedded systems. Exact input ranges, sample rates, references, and analog pin assignments are [DATA_NEEDED].
Recommended
Motor and Actuator Control
MCF51QU64VHS can support compact motor-control and actuator-management functions where deterministic embedded logic, local I/O, and compact packaging are important. The verified 32-bit processor at 50 MHz provides more general-purpose headroom than an 8-bit controller, while the 44-MAPLGA package allows integration into space-constrained assemblies. A production design must confirm PWM resources, timer channels, I/O voltage, protection features, and thermal limits; those details are [DATA_NEEDED].
Recommended
Building Automation Controllers
The MCF51QU64VHS is a reasonable candidate for building-automation modules that combine sensor monitoring, local decisions, and low-power operation. NXP describes the MCF51Qx family as offering ultra-low-power capabilities, and the verified MCU combines a 50 MHz 32-bit core with 64 KB Flash and a high-accuracy 16-bit ADC. The small package supports compact controller boards. Verify low-power current, wake-up sources, communication peripherals, and operating-temperature limits before selecting it for a deployed node.
Recommended
Instrumentation and Measurement Products
MCF51QU64VHS can serve as the control core for compact instrumentation that must combine analog measurement with embedded logic. The verified 50 MHz ColdFire V1 processor and 16-bit ADC provide the core resources for measurement sequencing, calibration handling, and user-interface support. Its 44-pin MAPLGA package can reduce system size, but exposed-pad handling, decoupling, reference design, and analog layout must follow the manufacturer documentation. ADC accuracy, calibration limits, and interface assignments are [DATA_NEEDED].
Recommended
Low-Power Embedded Products
The MCF51QU64VHS is suitable for low-power embedded products when compact size and configurable nonvolatile memory are priorities. NXP identifies ultra-low-power capabilities and configurable embedded EEPROM through the FlexMemory feature set, which can help products retain calibration or configuration data locally. The verified 64 KB Flash and 50 MHz core also provide useful control capability. Exact sleep currents, wake-up timing, retention requirements, and supply range are [DATA_NEEDED] and should drive the final architecture decision.

Key Differentiators
- Verified 50 MHz ColdFire V1 processing performance (vs MCF51QU128VHS)
- Verified 64 KB Flash configuration (vs MCF51QU128VHS)
- High-accuracy 16-bit ADC capability (vs MCF51JF64VHS)
- Compact 44-MAPLGA package (vs MCF51QU128VHS)
Design Notes
Treat the MCF51QU64VHS as a 44-terminal no-lead MCU rather than a generic QFN. Verify the manufacturer land pattern, terminal pitch, pin-1 orientation, and exposed-pad requirements before routing. Place decoupling capacitors close to the relevant power terminals and preserve the package-specific thermal and assembly geometry.
If the high-accuracy 16-bit ADC is used, separate analog inputs and references from switching or high-current paths where practical. Confirm the ADC pin locations and reference requirements in the official datasheet, then use short, quiet routing and a controlled ground return. The supplied data does not provide ADC acquisition timing or voltage limits, so those values must not be assumed.
Do not select MCF51JF64VHS, MCF51QM64VHS, or MCF51QU128VHS as a drop-in replacement solely because they appear in family comparison results. Compare pin names, alternate functions, Flash organization, voltage, clock settings, reset behavior, and package drawings first. The supplied sources do not establish complete interchangeability for those parts.
Compliance Information
The supplied verified data identifies an industrial temperature grade and active lifecycle status but does not provide RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 declarations.
