MCF5280CVF66J 概要
A Coldfire microcontroller is a 32-bit embedded processor family based on the Motorola 68000 instruction set architecture (ISA), engineered for low-cost, high-throughput control applications. The MCF5280 sits within the broader taxonomy of microcontroller -> embedded processor -> system-on-chip -> semiconductor, and was positioned for connectivity-rich industrial designs where deterministic Ethernet and CAN performance mattered more than flash density.
Key features include an integrated 10/100 Fast Ethernet MAC with MII/RMII interface, dual CAN 2.0B controllers, USB 1.1 (device mode on selected revisions), 4-channel 32-bit DMA, and a 4-channel 32-bit timers. The device operates across an industrial -40C to +85C temperature range with 3.3V I/O and 1.5V core supply. Multi-layer AHB/APB bus architecture enables concurrent DMA and CPU transactions, supporting real-time Ethernet throughput.
The MCF5280CVF66J uses a variable-length RISC Coldfire V2 core with enhanced multiply-accumulate (EMAC) unit, achieving 56 Dhrystone MIPS at 66 MHz. Memory map supports external SDRAM and flash interfaces through a 32-bit local bus plus dedicated chip-select controllers. Trace and debug are supported via BDM/JTAG, with on-chip breakpoint hardware.
Typical applications include industrial Ethernet PLC nodes, factory automation gateways, CAN-based motor controllers, building-automation routers, and networked sensor concentrators. The combination of Ethernet + CAN makes it well-suited for SCADA and remote I/O designs.
When designing with this ROMless part, designers must pair the MCF5280CVF66J with external NOR flash on the local bus. Total BOM cost typically requires placing 4-8 MB of 16-bit SRAM/flash externally. Power sequencing between 3.3V and 1.5V rails must follow NXP's reference manual; the 1.5V core rail must stabilize within 50 ms of the 3.3V rail for clean BDM debug handshake.
This page synthesizes distributor pricing, same-family and cross-brand drop-in alternatives, and practical design notes not found in the manufacturer datasheet - giving engineers a one-stop reference for both new designs and EOL/EOL risk migration paths.

主な用途
MCF5280CVF66J の用途: 6 件s: Industrial Ethernet PLC Node, Factory Automation Gateway, Building Automation Router, CAN-Based Motor Controller, Networked Sensor Concentrator, SCADA Remote I/O Module.
Industrial Ethernet PLC Node
The MCF5280CVF66J's integrated 10/100 Fast Ethernet MAC with MII/RMII and 66 MHz Coldfire V2 core make it well-suited for distributed PLC nodes communicating over Modbus TCP or EtherNet/IP. The dual CAN 2.0B controllers allow direct interfacing with field-bus servo drives without an external CAN transceiver MCU. The 16 KB cache and 4-channel 32-bit DMA offload the CPU from deterministic packet processing, while ROMless architecture supports bootloaders for remote firmware updates. Power dissipation at 66 MHz with 1.5 V core stays below 1 W, allowing fanless DIN-rail enclosure deployment.
おすすめ
Factory Automation Gateway
As a protocol-conversion gateway between Ethernet and CAN field-bus, the MCF5280CVF66J delivers 56 MIPS throughput at 66 MHz - enough to handle 100 Mbps Ethernet traffic and multiple CAN 2.0B streams concurrently via DMA. Its 4-channel 32-bit DMA engine enables parallel packet buffering without CPU intervention, and the coldfire V2 EMAC unit accelerates industrial checksum computation. External NOR flash (typically 4 MB) stores the gateway firmware plus Modbus/CANopen protocol libraries. The 17x17 mm MAPBGA-256 footprint fits compact panel-mount gateways.
おすすめ
Building Automation Router
Building automation routers aggregating BACnet/IP, KNX, and CAN traffic benefit from the MCF5280CVF66J's combination of Fast Ethernet and dual CAN controllers. The 66 MHz Coldfire V2 core runs BACnet stack plus routing logic at low power (typ 700 mW at full load), and the 2 KB on-chip SRAM plus 16 KB cache keep BACnet message buffers in fast memory. The industrial -40C to +85C operating range supports rooftop and basement installations. ROMless design allows field firmware upgrades by simply reflashing the external NOR via Ethernet.
おすすめ
CAN-Based Motor Controller
Variable-frequency drives and stepper controllers communicate over CANopen or DeviceNet using the MCF5280CVF66J's dual CAN 2.0B ports, which support 1 Mbit/s with hardware acceptance filtering. The 4-channel 32-bit DMA keeps PWM timing loops deterministic at 66 MHz while the Ethernet MAC provides commissioning/diagnostic access. Industrial temperature rating (-40C to +85C) handles drive cabinet ambient. The 32-bit Coldfire V2 core runs vector control algorithms plus CAN state machine concurrently. ROMless architecture allows cost-optimized external flash sizing.
おすすめ
Networked Sensor Concentrator
Distributed sensor concentrators aggregating hundreds of analog/digital sensor inputs over sub-GHz or RS-485 backhauls use the MCF5280CVF66J's Ethernet MAC to uplink to SCADA hosts. The 4-channel 32-bit DMA cycles through ADC sample buffers at high rate while the Coldfire V2 core compresses and timestamps data. Industrial temperature rating and ROMless design for flexible field firmware suit outdoor enclosure deployment. The 256-MAPBGA package footprint integrates well with stacked-DDR-style PCBs in compact sensor hubs.
おすすめ
SCADA Remote I/O Module
Remote I/O modules for SCADA systems using the MCF5280CVF66J leverage its Ethernet MAC for Modbus TCP uplink and dual CAN controllers for fieldbus expansion. The 66 MHz Coldfire V2 core handles up to 1000 I/O points per second with deterministic timing, while 16 KB cache reduces flash wait states. External SDRAM (8-16 MB) supports local logging during network outages. The 17x17 mm 256-MAPBGA package fits standard 100x100 mm remote I/O board form factors. Industrial -40C to +85C temperature ensures operation in unheated cabinets.

設計ノート
The MCF5280CVF66J requires two power rails: a 3.3 V supply for I/O and a 1.5 V core supply (typically 700 mA peak at 66 MHz). Both rails must ramp together within 50 ms per NXP reference manual to guarantee a clean BDM/JTAG debug handshake and avoid internal logic latch-up. Use a power management IC with sequenced output enable pins, or a discrete N-MOSFET load switch on the 1.5 V rail gated from the 3.3 V PG (Power Good) signal. Bulk capacitance: 22 uF tantalum plus 100 nF ceramic at each supply pin. Estimated total power dissipation at 66 MHz full DMA activity is approximately 1.0 W - within the 256-MAPBGA thermal envelope (theta_JA ~25 C/W on a 4-layer JEDEC PCB).
Route the external memory bus (32-bit local bus plus chip selects) with matched-length traces within 50 mil tolerance to preserve timing margins at 66 MHz. Place external SDRAM and NOR flash on the same PCB side as the MAPBGA-256, keeping trace length under 2 inches for the data bus. The exposed pad center of the MAPBGA-256 must be soldered to a thermal pad with at least 9 thermal vias (0.3 mm drill, 1.0 mm pitch) to the inner ground plane. Decoupling: 100 nF X7R per supply pin pair, plus 10 uF X5R bulk per rail. Use 4-layer PCB stackup with continuous ground plane beneath the BGA.
ROMless variants like the MCF5280CVF66J require boot configuration via external flash on chip-select CS0 - omitting external flash results in a 'no boot' BDM error. Do not confuse the VF (256-MAPBGA 17x17 mm) package suffix with VM (different package size) - the land patterns are NOT interchangeable. The 'J' suffix indicates lead-free/green, but older VF parts may be RoHS non-compliant per the Infinity Electron snapshot - verify RoHS status for EU export designs. Last-time-buy (LTB) windows for NRND parts are typically 12 months from the PCN date; place orders before final LTB cutoff to avoid losing the BOM line.
コンプライアンス情報
Legacy Freescale/NXP part. Per Infinity Electron snapshot, contains lead / RoHS non-compliant in original VF package; 'J' suffix indicates lead-free reflow compatible but verify each reel against manufacturer C of C. AEC-Q100 not applicable for industrial MCU.
