MCF5280CVF80 개요

The NXP MCF5280CVF80 is a ColdFire V2 32-bit RISC microcontroller integrated circuit operating at 80 MHz, supplied in a 256-ball 17 x 17 mm MAPBGA package, with part status marked Obsolete. The device belongs to the MCF528x family and integrates Ethernet, CANbus, UART/USART, I2C, and SPI connectivity along with DMA, LVD, POR, PWM, and a watchdog timer, with 142 user I/O pins.

A microcontroller (MCU) is a single-chip processing system that combines a CPU core, volatile and non-volatile memory, peripherals, and I/O in one package. ColdFire represents NXP/Freescale's 32-bit variable-length RISC architecture descended from the 68000 family, positioned between 8-bit MCUs and higher-end applications processors. Microcontrollers sit at the lowest tier of programmable logic hierarchy, above discrete logic ICs and below microprocessors/MPUs that require external memory and peripherals. MAPBGA (Mold Array Process Ball Grid Array) is a plastic BGA package family optimized for high-pin-count surface-mount designs where board space and signal integrity dominate.

Key features of the MCF5280CVF80 include 80 MHz ColdFire V2 core speed, ROMless program memory (external memory interface required), 142 I/O pins, and operating voltage referenced around 3.3 V typical. The integrated 10/100 Ethernet MAC makes it well suited for connected embedded systems, while the CANbus controller addresses industrial and automotive networking. Hardware DMA, PWM, and watchdog timers reduce CPU overhead in real-time control loops.

Architecturally, the ColdFire V2 core delivers a balance of code density and 32-bit throughput while keeping power and cost low. The MAPBGA footprint places traces and power/ground balls under the die for low inductance, and the wide connectivity set means a single MCF5280 device can replace a multi-chip UART/CAN/Ethernet external stack.

Typical applications include industrial Ethernet gateways, building automation controllers, motor-control front-ends, automotive telematics (non-safety-relevant), and point-of-sale terminals. Engineers also deploy it in CAN/Ethernet bridges, SCADA remote terminal units, and intelligent sensor hubs.

When designing with this part, observe thermal limits of the MAPBGA package and use a multi-layer PCB with stitched ground/thermal vias under the central ball grid for heat extraction. Because the part is Obsolete, verify Last Time Buy windows and plan second-source or migration to an active ColdFire/Kinetis equivalent before prototype freeze.

일반적인 애플리케이션

MCF5280CVF80 적합 용도: 6 애플리케이션s: Industrial Ethernet Gateway, Building Automation Controller, CAN/Ethernet Protocol Bridge, Motor Control Front-End (PWM/DMA), Point-of-Sale (POS) Terminal, SCADA Remote Terminal Unit (RTU).

🏭

Industrial Ethernet Gateway

The MCF5280CVF80 fits industrial Ethernet gateways because its 80 MHz ColdFire V2 core and on-chip 10/100 Ethernet MAC provide deterministic throughput and protocol handling for protocols such as TCP/IP, Modbus/TCP, and PROFINET. Its CANbus controller adds bridge capability to legacy fieldbus installations, enabling a single device to translate between CAN sensor networks and Ethernet SCADA backbones. The 142 user I/O pins allow multiple serial interfaces (UART/SPI/I2C) plus discrete lines for status LEDs and configuration switches, all without external logic. Compared to discrete Ethernet+MCU solutions, the integrated MAC eliminates a chip and reduces PCB area while the ColdFire V2 core delivers the 32-bit throughput needed at line rate. Designers should pair the device with an external PHY and a magnetics-isolated RJ45 jack, observing 4-layer PCB stack-up with continuous ground under the MAPBGA ball grid.

🏭

Building Automation Controller

For building automation, the MCF5280CVF80 combines 80 MHz ColdFire computation with multi-protocol connectivity (Ethernet, CANbus, UART, SPI, I2C), matching the heterogeneity of HVAC, lighting, and access-control subsystems in a single controller. The four UART/USART lines support simultaneous RS-485 trunks to BACnet or Modbus RTU devices, while the I2C and SPI buses connect local sensors and expansion modules. The integrated DMA engine offloads block transfers, leaving the ColdFire core free for protocol-stack scheduling. Compared with 8-bit MCUs, the 32-bit ColdFire V2 enables TCP/IP stacks and encryption libraries to fit in external Flash without crippling response latency. The MAPBGA-256 footprint keeps board space minimal for DIN-rail enclosures when paired with stackable daughter cards.

🌐

CAN/Ethernet Protocol Bridge

The MCF5280CVF80 is purpose-built for CAN/Ethernet protocol bridges because both controllers sit on the same chip, with DMA helping to absorb buffer copies between the two buses. Typical deployments include J1939-to-TCP gateways in heavy-equipment fleets, and CANopen-to-Modbus adapters in solar/wind inverter sites. At 80 MHz the ColdFire V2 core sustains the buffering and filtering arithmetic required for hundreds of CAN frames per second while maintaining a TCP socket open. The 142 I/O pins support the optional isolation couplers and CAN transceiver error lines alongside status/heartbeat LEDs. Unlike a stacked MCU+ASIC bridge, a single MCF5280 device reduces BOM by 30-40% on a comparable design.

⚡

Motor Control Front-End (PWM/DMA)

The MCF5280CVF80 is well-suited as a motor-control front-end controller because its PWM module generates precisely timed complementary outputs for three-phase inverter switches, while the DMA engine streams commanded duty cycles from memory without CPU involvement. The 80 MHz ColdFire V2 core executes FOC (field-oriented control) loop math within microsecond budgets, and the 142 I/O pins give full 6-channel PWM plus encoder feedback, current sense, and fault inputs without external mux. Though not designed for high-power safety-critical motor control, the MCF5280 is a strong fit for industrial pump/fan drives, conveyor controllers, and auxiliary motors. Pair with external gate drivers, current-sense amplifiers, and isolated CAN feedback (TJA1051) to complete the design.

🖥️

Point-of-Sale (POS) Terminal

POS terminal designers pick the MCF5280CVF80 because it integrates Ethernet (for IP-based payment gateways) plus UARTs (for receipt printers, barcode readers, MSR), I2C/SPI (for keypad, NFC/contactless modules), and the ColdFire V2 core running the terminal application stack. The 80 MHz speed-class keeps transaction latency low under PCI encryption workloads, and the 142 I/O pins support a color TFT LCD via external controller plus external PSRAM for the TLS handshake buffers. ROMless topology lets design teams encrypt and authenticate the boot image in external Flash plus secure element combination - a strong security posture for payment PCI-PTS requirements. MAPBGA-256 supports slim 8-10 inch tablet-form-factor POS designs.

🖥️

SCADA Remote Terminal Unit (RTU)

For SCADA RTUs, the MCF5280CVF80 provides an Ethernet DNP3/Modbus-TCP uplink with a CANbus downlink to substation instrumentation, plus UARTs for legacy RS-485 PLCs. The ColdFire V2 80 MHz core is more than sufficient for sub-second polling of dozens of IEDs and for running the embedded web/HMI config server. DMA timers and WDT fault handling support fault-tolerant RTU operation per IEC 61850-3 environments. The MAPBGA-256 and industrial-grade operating range ease thermal design in field cabinets. Designers typically pair the MCF5280 with surge-protected RS-485 transceivers, isolated CAN, and conformal-coated PCBs for harsh substation enclosures.

Does the MCF5280CVF80 include Ethernet and CAN?
Yes - the MCF5280CVF80 integrates a 10/100 Ethernet MAC plus a CANbus controller on-chip, alongside UART/USART, I2C, and SPI. This combination eliminates the need for external connectivity chips in small gateways, simplifying bill of materials and reducing PCB area versus discrete-stack alternatives. Verbatim from the MCF5280 series datasheet block diagram.
What package does the MCF5280CVF80 use?
The MCF5280CVF80 ships in a 256-ball MAPBGA (Mold Array Process Ball Grid Array) measuring 17 x 17 mm. MAPBGA provides high pin density for 32-bit MCUs and supports the wide bus and connectivity interface this device offers. Layout requires multi-layer PCB with stitched vias under the ball grid for thermal dissipation.
Is the MCF5280CVF80 still in production?
No - the MCF5280CVF80 is listed as Obsolete on DigiKey catalog data. Engineers targeting new designs should evaluate MCF528x replacement derivatives, ColdFire V2 successors, or active Kinetis/ARM Cortex-M alternatives within the NXP roadmap. Existing production lines should confirm Last Time Buy windows with NXP or authorized distributors.
What is the program memory configuration of MCF5280CVF80?
The MCF5280CVF80 is ROMless, meaning it has no internal non-volatile program memory and must fetch code from external memory through its EBI/EMI interface. This makes it suitable for systems that already require external SDRAM/Flash, or for prototyping where code size varies during development.
What peripherals are integrated on the MCF5280CVF80?
The MCF5280CVF80 integrates DMA, LVD (low-voltage detect), POR (power-on reset), PWM, and WDT (watchdog timer) peripherals, per the series datasheet. DMA offloads memory transfers, PWM supports motor control and lighting, and the WDT plus LVD/POR provides robust fail-safe startup behavior.
Where can I buy the MCF5280CVF80 today?
The MCF5280CVF80 can be purchased from authorized NXP distributors and major catalog houses such as DigiKey, Mouser, and Octopart-listed partners. Because the part is Obsolete, prices reflect long-term supply, and lead times are typically longer than active components. Always order from authorized channels to avoid counterfeit risk on obsolete parts.
What is the unit price of MCF5280CVF80?
Pricing for the MCF5280CVF80 has risen due to its Obsolete status and constrained supply - the unit price sits around $18.50 at qty 1 as of 2026-10-17, declining to roughly $10.95 at qty 1,000. Premiums of several multiples over the original MSRP are typical for end-of-life ColdFire devices, so redesign to an active alternative is often more economical long-term.
What is the lead time for MCF5280CVF80 orders?
Lead time for the obsolete MCF5280CVF80 is typically 8-16 weeks depending on distributor stock, per current DigiKey/Octopart inventory data. Some brokers carry small lots with shorter lead times at higher prices. For volume production, secure an LTB agreement with NXP or migrate to an active NXP ColdFire/Kinetis MCU.
What is the difference between MCF5280CVF80 and MCF5280CVM66?
The MCF5280CVF80 runs at 80 MHz, while the MCF5280CVM66 (and MCF5280CVF66) run at 66 MHz, per Xecor parametric comparison. Both share the same ColdFire V2 core, the same 256-MAPBGA package, and the same MCF528x series feature set, so the CVM66 is a 'drop-in' speed-grade downgrade if the 80 MHz timing budget is not required.
What is the difference between MCF5280CVF80 and MCF5280CVF66?
The MCF5280CVF80 runs at 80 MHz while the MCF5280CVF66 runs at 66 MHz, both ColdFire V2 32-bit, both 256-MAPBGA. The CVF80 offers approximately 21% higher throughput than the CVF66 at the same operating voltage; select the CVF80 only when compute budget mandates it, since CVF66 is cheaper and has more distributor stock on some channels.
Which Active alternatives exist for MCF5280CVF80?
Drop-in 80/66 MHz same-family parts (MCF5281CVF80, MCF5282CVF80, MCF5280CVM66, MCF5280CVF66) provide near-identical functionality in the same MAPBGA-256 footprint. For new designs, engineers commonly migrate to NXP Kinetis K60 or ColdFire V2 derivatives (e.g., MCF51QM/MCF52xxx) that retain the ColdFire ecosystem while offering active lifecycle status. Cross-brand options exist in ARM Cortex-M3 Ethernet-enabled MCUs but require schematic and PCB rework.
Where to download MCF5280CVF80 datasheet PDF?
The MCF5280CVF80 datasheet PDF is available from NXP/Freescale at www.nxp.com, archive mirrors such as alldatasheet.com (HTML index), and the original Freescale MCF5280 reference manual (766-page document) at alldatasheet.net.

선택 가이드

Choose the MCF5280CVF80 only when maintaining an existing production design that explicitly requires the 80 MHz ColdFire V2 variant - this part is officially Obsolete so redesign is strongly preferred for new projects. Within the MCF528x family, choose MCF5281CVF80 / MCF5282CVF80 for richer peripheral sets, or MCF5280CVF66 / MCF5280CVM66 to save cost when 66 MHz is sufficient. For all new designs, migrate to a currently active NXP Kinetis or ColdFire derivative (e.g., MCF52xxx) to escape the obsolete supply chain. Cross-brand ARM Cortex-M3 Ethernet-enabled MCUs (e.g., STM32F107) require complete schematic and PCB rework; reserve that effort for clean-slate redesigns rather than substitution.

설계 노트

The MCF5280CVF80 in 17 x 17 mm MAPBGA has relatively high thermal mass spread across its ball grid; the central balls dominate heat dissipation. Design the PCB with a multi-layer stack-up (typically 4-6 layers) and stitch a thermal via array underneath the center ball region for heat extraction to the inner ground plane. At 80 MHz ColdFire V2, typical core power dissipation in the 500 mW-1 W range under Ethernet activity, so 1 oz copper with thermal vias is generally adequate for industrial enclosures without forced airflow. Estimated: worst-case junction-to-ambient at 0 m/s airflow with proper via stitching is roughly 25-30 C/W theta_JA.

When laying out the 256-ball MAPBGA, follow 0.8 mm ball pitch design rules with non-solder-mask-defined (NSMD) pads and a 0.4 mm via/pad diameter for breakout. Keep inner-layer reference planes continuous under all balls to control return-current inductance - this matters especially for the Ethernet MAC balls which run at 25 MHz and 100 MHz harmonics. Place the external SDRAM and Flash as close to the EBI/EMI balls as possible to minimize bus stubs. Decouple every VDD ball with 0.1 uF X7R + bulk 10 uF on the same side.

The most common pitfall on MAPBGA-256 cold-fire designs is forgetting to strap the configuration pins (chip-mode and EBI width) on reset release - the chip boots with a default that may not match your memory map. Another frequent issue is power-rail sequencing: VDD must ramp up monotonically before the POR (power-on reset) de-asserts the cold-fire PLL, otherwise the PLL can latch into an unstable lock. Always honor the 1 ms minimum RESET hold after VDD crosses 3.0 V. Because the part is Obsolete, also re-verify any errata against the latest NXP PCN list before final prototype freeze.

Treat the Ethernet MAC signals (ETHTX+/-, ETHRX+/-) as 100BASE-TX differential pairs of 100 ohms differential impedance, with length-matched traces within 150 mil tolerance and no more than two vias on the MII path. Series-terminate each MAC output to dampen overshoot. Keep MAC clocks on the inner layers of a stripline topology when practical; if microstrip is unavoidable, the reference ground plane must be unbroken for the entire trace run. The 80 MHz ColdFire core and DMA bus can show edge rates in the 1 ns range, so all switching signals benefit from short, well-decoupled traces.

Separate analog and digital grounds with a single-point stitch under the MAPBGA; route the external PHY's analog ground island back to this same stitch. The CAN bus balls should be guarded with TVS diodes (e.g., PESD1CAN) close to the connector side, and 100 nF + 10 uF decoupling on each VDD island. Do not place any high-speed switching signal traces under the central ball grid because the center balls carry decoupling and noise immunity suffers. Reference the MCF528x hardware design guide from NXP (legacy Freescale) for the full layout checklist.
