MCF51CN128CL - 32-Bit 50MHz 128KB Flash MCU | NXP
MPN: MCF51CN128CL ✗ Cuối đờiMCF51CN128CL Tóm tắt
A microcontroller is an integrated circuit containing a processor core, nonvolatile program memory, data memory, peripherals, and input/output interfaces in one device. The MCF51CN128 belongs to the ColdFire microcontroller family and is positioned between a general-purpose MCU and more specialized network-control devices. Its Ethernet controller makes it relevant to industrial networking, embedded gateways, control panels, and communication equipment, provided the complete electrical and software requirements remain satisfied.
The verified information identifies a 50 MHz ColdFire V1 core, 128 KB flash memory, 32-bit architecture, 10/100 BASE-T/TX fast Ethernet capability, MII connectivity, and a multi-function external bus interface. The package information is listed as 64-LQFP, 10 mm by 10 mm. Other electrical details, RAM size, pin-level assignments, operating voltage, temperature range, and peripheral inventory were not provided in the verified data and therefore require confirmation from the manufacturer datasheet before design release.
The Ethernet block uses an MII interface to connect to an external physical-layer transceiver. Designers should account for the external PHY, magnetics, clocking, termination, isolation, and signal-integrity requirements of the Ethernet implementation. The multi-function external bus provides a route for additional peripherals, but the supported operating modes and electrical timing must be taken directly from the MCF51CN128 datasheet.
Typical application areas include industrial Ethernet controllers, embedded network management equipment, data acquisition systems, and connected industrial products. For each use case, confirm the required memory map, I/O availability, bus timing, supply voltage, and software support. The MCF51CN128CL is specifically associated with an end-of-life overview in the verified NXP product result, so sourcing and lifecycle planning should account for the device's current availability.
This product record consolidates the verified NXP datasheet link, distributor package and memory information, and the available product-page context into a practical procurement reference. For a new PCB, use the official datasheet as the controlling document rather than relying on abbreviated distributor descriptions.

Ứng dụng tiêu biểu
MCF51CN128CL phù hợp cho 6 Áp dụngs: Industrial Ethernet Controller, Embedded Network Gateway, Data Acquisition and Control, Connected Industrial Equipment, Communication Equipment, Networked Test and Measurement Instrument.
Industrial Ethernet Controller
The MCF51CN128CL is a rational fit for industrial Ethernet control equipment because the verified device specification identifies a 10/100 BASE-T/TX fast Ethernet controller, an MII interface, and a 32-bit ColdFire V1 core operating up to 50 MHz. The MCU can manage protocol and supervisory tasks while an external PHY handles the physical network layer. A practical design should reserve the MII routing for short, controlled signal paths and follow the NXP and PHY reference guidance. Because the verified excerpts do not state operating temperature, supply voltage, or lifecycle guarantees, industrial qualification and long-term sourcing must be checked before production.
Được đề xuất
Embedded Network Gateway
The MCF51CN128CL can serve as the control processor in an embedded network gateway when the design needs local Ethernet connectivity and a 32-bit embedded architecture. Its verified 50 MHz ColdFire V1 core and 128 KB flash provide a defined platform for network management, protocol handling, and supervisory logic. The MII interface requires an external PHY, so the complete gateway design must include suitable magnetics, clocking, isolation or protection as required, and controlled board layout. Confirm RAM, I/O availability, operating limits, and software support from the official datasheet before fixing the architecture.
Được đề xuất
Data Acquisition and Control
For data-acquisition equipment, the MCF51CN128CL offers a 32-bit ColdFire V1 processing platform at 50 MHz with 128 KB flash and a multi-function external bus. That combination can support local control loops, data formatting, status monitoring, and communication tasks when the exact peripheral and I/O requirements are confirmed. The external bus may be used to connect additional functions, but its electrical timing and supported modes must be taken from the official NXP documentation. The verified data does not specify ADC performance, RAM, timers, or operating temperature, so this part should not be selected for precision analog performance without further review.
Được đề xuất
Connected Industrial Equipment
MCF51CN128CL is applicable to connected industrial equipment that needs Ethernet communications and deterministic embedded control in a compact 64-LQFP 10 mm x 10 mm package. The verified 32-bit ColdFire V1 core at 50 MHz can handle network-related control software, while the multi-function external bus provides a path for system integration. In a real product, the Ethernet PHY, magnetics, isolation, and power design may dominate board-level complexity. Validate industrial temperature, EMC, ESD, and lifecycle requirements separately because these attributes are not established by the supplied distributor snippets.
Được đề xuất
Communication Equipment
The verified 10/100 BASE-T/TX Ethernet capability makes MCF51CN128CL relevant to communication equipment that needs an embedded network interface alongside application-level control. The 32-bit ColdFire V1 core operating at 50 MHz can support protocol processing and supervisory tasks, while the 128 KB flash provides the specified nonvolatile program-memory capacity. The MII architecture means the MCU is not a standalone Ethernet solution; the external PHY and network magnetics must be selected and placed carefully. Confirm memory requirements beyond flash, baud-rate or protocol support, and operating conditions against the official datasheet.
Được đề xuất
Networked Test and Measurement Instrument
The MCF51CN128CL may be used in networked test or measurement equipment when the instrument needs a 32-bit control processor and Ethernet connectivity. Its verified 50 MHz ColdFire V1 core, 128 KB flash, MII interface, and external bus provide a starting point for supervisory control, logging, and instrument communication. The component's suitability still depends on analog interfaces, precision timing, RAM, operating temperature, and calibration requirements that are not specified in the supplied data. Use the official datasheet to verify those resources and then validate EMC and network performance at system level.

Ghi chú thiết kế
Treat the MCF51CN128CL Ethernet implementation as an MII-based external-PHY design. Place the MCU and PHY according to the NXP and PHY reference guidance, keep MII traces short and controlled, provide a continuous ground reference, and avoid unnecessary stubs. The verified data confirms the MII interface but does not specify signal timing, so the official datasheet and selected PHY documentation are required before releasing the layout.
Before power-supply design, obtain the MCF51CN128CL operating-voltage and current limits from the official datasheet. The supplied evidence confirms a 32-bit, 50 MHz MCU with Ethernet and external-bus capability but does not provide supply values. Do not infer supply requirements from the package or core frequency. Validate the complete rail plan against MCU, PHY, magnetics, and external-bus loading, including startup and maximum operating conditions.
Do not substitute a related MCF51CN128 suffix based only on family naming. MCF51CN128CLH and MCF51CN128CLK appear in the verified search results, but the supplied evidence does not prove that either exact orderable device is pin-to-pin, electrically equivalent, or lifecycle-equivalent to MCF51CN128CL. Compare the official ordering table, package drawing, pin table, electrical characteristics, and lifecycle notices before approving a replacement.
Plan the board around the verified 64-LQFP, 10 mm x 10 mm package only after checking the official package drawing for pin numbering, pad dimensions, exposed thermal features if any, and recommended land pattern. The supplied data does not include a pinout or package drawing details. Preserve access to all power, ground, reset, clock, MII, and external-bus signals, and verify the land pattern against the manufacturer document rather than relying on a generic LQFP drawing.
