MCF51JM32VQH 概要
A microcontroller is a compact integrated circuit containing a processor core, memory, and peripherals for controlling a specific embedded system. The MCF51JM belongs to the ColdFire family of 32-bit RISC microprocessors and is positioned within NXP's Flexis MCU ecosystem. The Flexis approach links compatible 8-bit S08 and 32-bit ColdFire V1 families through shared peripherals and development tools, helping designers migrate designs while adapting software and pin requirements to the selected device.
The verified specifications identify a 32-bit data bus, ColdFire V1 core, 50 MHz operating frequency, 32 KB flash organized as 32K x 8, and 16 KB RAM. The 64-QFP package provides 64 external pins and a 14 mm by 14 mm body. The supplied product information does not specify the complete peripheral list, GPIO count, supply-voltage minimum and maximum, operating-temperature range, or package thermal resistance, so those values remain marked for data completion rather than being inferred.
MCF51JM devices are used for embedded-control and peripheral-coordination functions. Potential designs include industrial controllers, communication equipment, data-acquisition systems, and compact motor or machine-control products when the firmware and board requirements match the MCF51JM peripheral configuration. The 32-bit core and 50 MHz frequency support more demanding control logic than an 8-bit MCU, while the integrated flash and RAM allow firmware and working data to reside locally in the system.
When designing around the MCF51JM32VQH, verify the exact pin assignments, alternate-function multiplexing, clock configuration, memory organization, and electrical limits against the manufacturer datasheet before PCB routing. Because the MCU is marked End of Life by the NXP product page, new production decisions should include a lifecycle review, availability check, and confirmation of any approved successor or redesign path rather than assuming long-term supply.
This page combines the verified manufacturer and distributor specifications, lifecycle information, package details, practical sourcing guidance, and documented data gaps. It is intended to support engineering comparison and procurement review while avoiding unsupported claims about electrical limits, peripheral compatibility, or replacement parts.

主な用途
MCF51JM32VQH の用途: 6 件s: Industrial Embedded Controller, Data-Acquisition System, Communication Equipment Controller, Compact Machine-Control Board, Peripheral Coordination Hub, Legacy System Maintenance.
Industrial Embedded Controller
The MCF51JM32VQH fits an industrial embedded controller that requires a 32-bit ColdFire V1 core at up to 50 MHz, together with local 32 KB flash and 16 KB RAM for control firmware and working data. Its 64-QFP package provides a defined external-pin footprint for a conventional surface-mounted control board. The design should verify the exact GPIO map, timers, communication peripherals, electrical limits, and environmental requirements in the NXP datasheet before assigning functions to the package pins.
おすすめ
Data-Acquisition System
A data-acquisition product can use the MCF51JM32VQH's 32-bit RISC core to coordinate sampling, data handling, communications, and control functions in one device. The verified 50 MHz maximum frequency provides a defined processor target, while 32 KB flash and 16 KB RAM support embedded firmware and a local working buffer. The MCU is suitable only after the design confirms the required ADC, timer, serial interface, analog signal levels, and package pin assignments; those specifications are not present in the supplied verified data.
おすすめ
Communication Equipment Controller
The MCF51JM32VQH can serve as the central embedded controller in communication equipment when the board needs local real-time control, protocol coordination, and system monitoring. Its 32-bit ColdFire V1 architecture and 50 MHz rating provide more execution headroom than an 8-bit MCU, while 32 KB flash and 16 KB RAM are useful for firmware, configuration, and buffers. The exact UART, SPI, CAN, or other interface capabilities are not supplied and must be verified before selecting the MCU for a specific communication standard.
おすすめ
Compact Machine-Control Board
For a compact machine-control board, the MCF51JM32VQH provides a 32-bit processor core, local program memory, and a 64-pin QFP interface in a 14 mm by 14 mm package. It can coordinate sensors, actuators, timing functions, and operator interfaces when its verified peripherals match the system requirements. Because the supplied sources do not define pulse-width-modulator channels, analog inputs, digital I/O count, or operating-temperature limits, the MCU should remain provisional until those electrical and functional details are confirmed.
おすすめ
Peripheral Coordination Hub
The MCF51JM32VQH is described in the verified supplier data as suitable for embedded control and peripheral coordination. That makes it a reasonable architecture candidate for a board that must supervise sensors, memory, communications, and actuators while executing local firmware. Its 32 KB flash and 16 KB RAM provide the stated baseline memory capacity, and the 50 MHz ColdFire V1 core handles the control task. Exact peripheral multiplexing and interrupt resources must be checked in the datasheet rather than inferred from the processor family.
おすすめ
Legacy System Maintenance
The MCF51JM32VQH may be appropriate for maintaining an existing ColdFire-based product, particularly where changing software or hardware would be more disruptive than sourcing the established device. The verified distributors list the part as a 32-bit, 50 MHz, 32 KB flash and 16 KB RAM MCU in a 64-QFP package, which supports initial board identification and replacement screening. Since NXP marks the product End of Life, maintenance teams should secure authorized traceability and avoid assuming that every listed distributor stock will remain available.

設計ノート
Do not approve a replacement based only on the 50 MHz rating and 64-QFP package name. Verify the complete manufacturer pinout, alternate-function assignments, memory map, clock requirements, peripheral availability, electrical limits, and software identifiers. The verified data does not provide a pin-by-pin table, so the pinout is intentionally null and must be obtained from the NXP documentation before layout or schematic approval.
Before routing the power pins, confirm the exact minimum and maximum supply voltages, I/O voltage domains, decoupling values, power-up sequencing, and external component recommendations in the manufacturer datasheet. The supplied distributor references associate the part with 3.3 V and 5 V configurations, but those descriptions are not sufficient to design a power tree or select the correct logic-level interfaces.
Treat the 64-QFP as a 64-pin surface-mount package and preserve the manufacturer land pattern, pin numbering, exposed thermal or center-pad details, solder mask, and paste recommendations. The verified sources identify the body as 14 mm by 14 mm but do not provide a package drawing or pin table. Do not infer a generic QFP footprint until the exact NXP package drawing is checked.
Calculate junction temperature from the actual supply voltage, I/O activity, clock loading, and ambient conditions using the manufacturer thermal model. The provided data does not include power dissipation, thermal resistance, or maximum junction temperature, so no numerical thermal result can be verified. For legacy or end-of-life systems, include thermal margin and monitor component temperature during qualification rather than relying on a nominal processor frequency.
Plan for lifecycle and software risk at the same time as hardware risk. NXP identifies MCF51JM32VQH as End of Life, while distributor inventory and reference pricing may be temporary. Confirm remaining-life notices, authorized sourcing, date codes, firmware and tool compatibility, and any approved successor before freezing a production release.
コンプライアンス情報
The supplied verified data identifies NXP lifecycle information and distributor catalog specifications but does not provide verified RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification statements. Compliance status therefore remains unknown.
