MCF5272CVF66J - ColdFire V2 66MHz 32-bit MCU | NXP

A ColdFire V2 microprocessor is a reduced-instruction-set (RISC) 32-bit core derived from the Motorola 68000 architecture lineage. In the embedded system hierarchy it sits between simple microcontrollers and high-end application processors, offering a variable-length instruction set (16/32/48-bit), a single-issue pipeline, and a rich peripheral set. The MCF527x family was designed by Freescale Semiconductor, now part of NXP, specifically to combine high integration and low cost with a new level of performance on the popular ColdFire V2 core.
Key features of the MCF5272 include the 66 MHz V2 core, 4K x 32 on-chip SRAM, an integrated Ethernet MAC for connectivity, UARTs for serial communication, and a combination of connection, protection, and peripheral selection that makes the device well suited to cost-sensitive, power-conscious designs. According to the NXP product page, the MCF527x is ideal for applications requiring significant control processing for file management, connectivity, data buffering, and user interface tasks.
Technically, the device integrates the ColdFire V2 processor with system logic, memory controllers, and communication peripherals on a single die, reducing external component count and board area. The 196-ball MAPBGA (15x15 mm) footprint provides a dense but manufacturable surface-mount solution, and the 3.3 V I/O and core supply simplifies power tree design relative to older 5 V 68K-family parts.
Typical applications include industrial networking nodes, protocol converters and gateways, data buffering systems, human-machine interface panels, and embedded control systems that need Ethernet-class connectivity with moderate compute throughput. The integrated peripherals and mature ColdFire tool ecosystem suit long-lifecycle industrial equipment.
When designing with the MCF5272CVF66J, note that the part is listed as obsolete by distributors such as DigiKey and Mouser; new designs should evaluate migration paths, while legacy designs should secure last-time-buy stock or a qualified drop-in family variant.

典型應用
MCF5272CVF66J 適用於 6 應用s: Industrial Networking Nodes, Protocol Converters and Gateways, Data Buffering Systems, Human-Machine Interface Panels, Embedded Control Systems, Legacy Sustaining Engineering.
Industrial Networking Nodes
The MCF5272CVF66J fits industrial networking node designs because its integrated Ethernet connectivity and 66 MHz ColdFire V2 core deliver enough throughput for protocol handling without a external network coprocessor. In a typical node, the MCU services the Ethernet MAC, manages UART-linked field devices, and buffers traffic in the 4K x 32 on-chip SRAM while application code runs from external memory. Performance consideration: the 66 MHz single-issue pipeline suits 10/100 Mbps bridging and protocol conversion, but sustained line-rate packet processing with heavy checksum work should be benchmarked, as software stacks consume most of the core margin. The 3.3 V single-rail supply simplifies industrial power design.
推薦
Protocol Converters and Gateways
Gateway designs benefit from the MCF5272CVF66J because NXP explicitly targeted the MCF527x at file management, connectivity, and data buffering workloads. The device bridges serial (UART) traffic to Ethernet, translating protocols between legacy field equipment and modern networks. The 16 KB (4K x 32) on-chip ROM holds boot code while firmware resides in external flash, and the 196-ball MAPBGA provides the I/O count needed for multiple UART channels plus the MAC. Design consideration: conversion latency is dominated by the 66 MHz core handling software protocol stacks; designers should budget cycle counts carefully and use DMA-driven UART transfers where the peripheral set allows to keep jitter low in time-sensitive conversions.
推薦
Data Buffering Systems
Data buffering applications align directly with the stated MCF527x target of data buffering per the NXP product page. The MCF5272CVF66J's on-chip SRAM combined with external memory control supports queuing tasks, logging, and intermediate storage between a fast network interface and slower serial or storage peripherals. At 66 MHz the V2 core can sustain buffer management, descriptor walking, and checksum tasks at moderate data rates. Performance consideration: because the 4K x 32 internal SRAM is small, buffering strategies should keep hot descriptors on-chip and bulk payloads in external SRAM to avoid contention; verifying external memory wait states is essential to achieving expected throughput in buffering-intensive designs.
推薦
Human-Machine Interface Panels
HMI panels are a classic MCF527x use case because the family was designed for applications with significant user interface processing. The MCF5272CVF66J at 66 MHz handles menu rendering logic, keypad scanning, and communication back to a controller over UART or Ethernet. The 196-ball MAPBGA package exposes enough parallel and serial I/O for display and touch interfaces, and the 3.3 V supply simplifies integration with modern display modules. Trade-off: there is no dedicated graphics accelerator, so frame rendering must be efficient firmware; text-heavy and segmented-display interfaces work best. The mature ColdFire tool ecosystem, including long-standing GNU toolchain support, eases long-term HMI maintenance for industrial equipment.
推薦
Embedded Control Systems
General embedded control systems use the MCF5272CVF66J where a 32-bit 68K-lineage instruction set, moderate 66 MHz performance, and integrated connectivity peripherals are required in one package. The ColdFire V2 variable-length instruction set yields compact code, beneficial when firmware resides in cost-optimized external flash. The single-chip integration of system logic reduces BOM count versus discrete CPU-plus-logic designs, and the 15x15 mm 196-MAPBGA footprint is manufacturable with standard reflow. Design consideration: because the part is obsolete, control-system designers should either implement a last-time-buy for the equipment's service life or design a pin-compatible MCF5272 variant substitution plan before committing new control hardware to this MPU.
推薦
Legacy Sustaining Engineering
A primary current application of the MCF5272CVF66J is sustaining engineering for installed industrial, medical, and networking equipment already designed around the MCF5272. Per NXP community threads, customers of the discontinued MCF5272CVM66 actively seek replacement ICs, and legacy-stock channels such as Rochester Electronics exist precisely for this purpose. Recommended practice: qualify MCF5272VF66R2 or MCF5272CVM66J (same 196-MAPBGA footprint) as approved substitutions, document firmware boot pin settings, and secure dated-code stock with certificate of conformance. Note that every MCF5272 variant is also obsolete, so total inventory for remaining service life must be calculated and purchased in one or staged buys.

設計說明
The MCF5272CVF66J is obsolete as of 2026-10-18: both DigiKey and Mouser listings route through Rochester Electronics or remaining stock, and the NXP community has confirmed discontinuation discussions for sibling parts like MCF5272CVM66. Before committing any design change, compute the total lifetime requirement for the equipment and place a single consolidated last-time-buy with a date-code and certificate-of-conformance requirement. Do not qualify more than one alternate suffix unless your firmware tolerates boot-setting differences between ordering codes.
The 196-MAPBGA (15x15 mm) is a fine-pitch BGA; use the manufacturer-recommended land pattern and follow the NXP/Freescale ColdFire hardware design guide for via-in-pad or dog-bone fanout. Decouple all VDD/VSS ball pairs with low-ESR ceramics placed directly beneath or beside the package. Because the core runs at 66 MHz with external memory interfaces, keep address/data bus lengths matched within the skew budget in the reference manual to avoid marginal read timing at temperature extremes.
The device operates from a 3.3 V supply. Provide a regulated 3.3 V rail with sequencing respected per the datasheet power-up requirements, and budget current for both core and I/O plus external memory accesses at 66 MHz. Estimated: total active current depends heavily on external bus activity and was not published in the verified data, so measure or consult the reference manual electrical chapter before sizing the regulator rather than assuming a worst-case value.
