The NXP Semiconductors MCF5274LVM166 is a 32-bit, 166 MHz ColdFire V2 integrated microprocessor with 64K x 8 RAM, ROMless architecture, 61 I/O connections, and a 196-LBGA package measuring 15 x 15 mm. It is designed for cost-sensitive, power-conscious embedded systems that require significant control processing, connectivity, data buffering, and file-management capability. A microprocessor is a programmable control component that executes instructions, manages system resources, and coordinates peripherals. The ColdFire architecture belongs to the 32-bit RISC microprocessor hierarchy, while MCF5274LVM166 integrates the processor, memory interfaces, I/O, and communication-oriented peripherals into one system-on-chip solution. Its 166 MHz operating speed supports embedded control workloads without requiring a separate external memory array for the stated 64K x 8 RAM configuration. The principal verified characteristics are a 166 MHz core frequency, 32-bit processing, 64K x 8 RAM, 61 I/O, ROMless operation, and a 196-LBGA package. The ROMless architecture allows firmware and boot code to reside in external nonvolatile memory, providing flexibility for application-specific code storage and field updates. The 196-LBGA package is intended for high-density PCB layouts where fine-pitch interconnect and multilayer construction are practical. The ColdFire V2 processor is positioned for embedded networking, industrial control, communications, data buffering, and file-management equipment. Its integrated peripheral selection can reduce the need for separate interface controllers in systems where the selected peripheral functions match the design requirements. Designers must still validate pin multiplexing, memory topology, voltage limits, clocking, and signal integrity against the complete hardware specification before layout release. The verified source data identifies the device as an NRND NXP product, so new production designs should confirm lifecycle availability and migration options before committing. The MCF5272VM66J from the Site MPN list may be relevant for family-level evaluation, but it is not included as a drop-in alternative because its package and exact pin compatibility are not verified by the supplied data. The 196-LBGA footprint also requires careful escape-routing, via-in-pad policy, thermal management, and assembly-process qualification. MCF5274LVM166 is best treated as a legacy embedded-control platform rather than a generic substitute target. Its 166 MHz ColdFire V2 performance, 64K x 8 RAM, external-memory architecture, and 196-LBGA integration are the main decision points. This page synthesizes the verified manufacturer and distributor listings, lifecycle status, package information, practical implementation guidance, and explicitly identifies missing technical data instead of inventing specifications.

Architecture-wise, the ColdFire V2 core implements a 4-stage pipeline with 16-bit and 32-bit instruction mix that improves code density over MIPS/ARM Thumb counterparts. The integrated Fast Ethernet controllers, USB, and CAN peripherals collectively allow bill-of-materials reduction by eliminating external PHY and protocol chips, while the hardware encryption engine offloads AES-128, DES, and SHA-1 from the CPU. Typical applications include industrial control and automation gateways, factory-floor protocol converters, POS and kiosk terminals, networked printer controllers, building-automation control panels, and remote monitoring/edge gateway products. The wide peripheral mix and on-chip networking make this part well suited where Linux or RTOS-based control plus deterministic Ethernet and fieldbus connectivity are required. When designing with this part, allocate sufficient PCB area for the MAPBGA fanout and follow NXP's reference design for DDR/SDRAM trace matching, since high-speed external memory interfaces are sensitive to impedance mismatch. Also confirm supply voltage sequencing to satisfy the 1.5 V core requirement before enabling the I/O 3.3 V rail, per the manufacturer datasheet.

The NXP Semiconductors MCF5275LCVM166 is a 32-bit ColdFire V2 integrated microprocessor (MPU) running at 166 MHz core clock, housed in a 196-pin LBGA (15x15 mm) package. The MCF527x family integrates 64KB of on-chip SRAM, an eMAC Ethernet controller, USB, and a rich ColdFire V2 peripheral set, targeting connected embedded applications where deterministic control plus TCP/IP throughput is required. An MPU (microprocessor unit) is a CPU-centric system-on-chip that requires external memory for program storage, in contrast to a microcontroller (MCU) which integrates flash and is optimized for standalone firmware. The ColdFire V2 architecture itself is a variable-length RISC ISA derived from Motorola 68000, providing a 32-bit programming model while keeping die area, power, and cost comparable to 16-bit MCUs - a sweet spot for industrial control, building automation, and connected appliances. Key features of the MCF5275LCVM166 include a 166 MHz ColdFire V2 core delivering approximately 159 MIPS, an integrated 10/100 Ethernet MAC with MII/RMII interface, a USB 2.0 full-speed device/host controller, 64KB of unified SRAM, a 16-channel eDMA engine, four 32-bit timer units, dual UARTs, dual I2C, and a 16-bit external bus interface for SDRAM, SRAM and ROM. The 196-LBGA package exposes the full address/data bus and is designed for multi-layer PCB layouts with a thermal resistance suitable for fanless industrial enclosures. Architecturally, the ColdFire V2 core uses a Harvard-style split I/D bus and an enhanced multiply-accumulate (EMAC) unit, which accelerates signal-processing kernels common in motor control. An on-chip PLL synthesizes the core clock from an external reference, and the integrated voltage regulator generates internal rails from a single 3.3 V supply, simplifying board design. Typical applications include industrial Ethernet gateways, building automation controllers, point-of-sale terminals, networked sensors, factory-floor protocol bridges (Modbus/TCP, EtherNet/IP), and USB peripherals. For designs targeting lower cost without Ethernet, the MCF5274 drop-in alternative is commonly used; for designs needing higher performance, the MCF528x family scales up to 80 MHz while sharing much of the same peripheral IP. Designers should allocate at least four PCB layers and provide adequate thermal vias under the LBGA to keep junction temperature within range. Watch for SDRAM trace-length matching, since the EBI bus runs at one half of the core clock.

The V2 core variant targets cost-sensitive embedded networking and industrial applications, balancing processing throughput against deterministic interrupt latency, and sits in the broader product hierarchy: ColdFire V2 -> ColdFire family -> 32-bit microcontroller -> embedded MCU. ROMless parts such as the MCF5280CVM80J are intended for systems that pair the MCU with an external flash memory bank, allowing the OEM to choose memory density, boot strategy, and security layout independently from the processor silicon. Key features include 80 MHz maximum CPU clock, 32-bit ColdFire V2 core, ROMless program memory interface, integrated 10/100 Ethernet MAC, CAN 2.0 controller, multiple UART/SPI/I2C channels, 16-bit timer units, and an external memory controller for SRAM/flash expansion. The device supports JTAG/BDM debug and is supported by NXP's CodeWarrior and the broader ColdFire toolchain. The 256-ball MAPBGA package provides high I/O density for embedded networking and human-machine interface (HMI) designs where board space is at a premium. The MCF5280 architecture combines a ColdFire V2 core with on-chip SRAM and a sophisticated peripheral set designed for Ethernet- and CAN-connected industrial nodes. ROMless operation means the external memory controller drives an external flash and SRAM, giving designers flexibility in choosing boot memory, security features, and in-field firmware update strategy. Industrial temperature grading and a 17x17 mm BGA footprint make it suitable for factory automation controllers and ruggedized embedded modules. Typical applications include industrial automation controllers, embedded Ethernet nodes, CAN-based motor control front-ends, building automation gateways, and point-of-sale terminals. For cost-sensitive variants in the same family the MCF5281/5282/5283 add on-chip flash, while ROMless members such as this part are chosen when external memory density or firmware partitioning is required. When designing with this device, ensure PCB layout provides continuous ground and a low-impedance supply for the BGA core. Trace length matching on the Ethernet MII bus to the PHY is critical to keep signal integrity within IEEE 802.3 timing masks. Borehole-in-pad BGA assembly requires via-in-pad plating for thermal and electrical reliability.

The NXP MCF5281CVM66 is a 32-bit ColdFire V2 microcontroller (MCU) running at 66 MHz with 256 KB of on-chip flash memory, integrated Ethernet and CAN peripherals, packaged in a 256-ball MAPBGA (17x17 mm). According to the manufacturer product page, the part carries an NRND (Not Recommended for New Designs) lifecycle flag, indicating it remains available for existing designs but NXP is steering new projects to successor ColdFire parts. A ColdFire microcontroller belongs to the M68k microprocessor family (Motorola 68000 instruction set lineage) and occupies a middle ground between 8/16-bit legacy MCUs and full 32-bit PowerPC cores. The ColdFire V2 core delivers deterministic interrupt response, a unified 32-bit address space, and significantly higher code density than typical ARM Cortex-M parts at comparable MHz. Within the broader taxonomy, MCF5281CVM66 sits as: 32-bit microcontroller -> ColdFire V2 -> MCF528x family -> embedded MCU with Ethernet/CAN, suitable for industrial control, building automation, and networked sensor gateways. Key features include 256 KB flash with 8 KB SRAM (typical for the MCF528x family), 10/100 Ethernet MAC, FlexCAN module, three UARTs, QSPI, I2C, an eTPU timer coprocessor, a 4-channel 12-bit (or 10-bit, family-dependent) ADC, and a hardware encryption accelerator (CAU on some MCF5281 mask sets).

The NXP MCF5281CVM66J is a 32-bit ColdFire V2 microcontroller integrated with 256 KB of on-chip flash memory, a 66 MHz CPU core, and a rich communications peripheral set including 10/100 Ethernet MAC, CAN, three UARTs, an I²C bus, and queued SPI. Housed in a 256-ball MAPBGA package measuring 17 x 17 mm, the device targets embedded networked applications that previously required an external MCU plus a separate communications controller. According to the NXP MCF528X product page, the family is "designed to simplify embedded Ethernet-networked MCU applications" by integrating MAC and PHY interfaces alongside the ColdFire V2 core. A ColdFire V2 microcontroller is a 32-bit embedded processor derived from the original 68000 instruction set architecture (ISA), optimized for code density and deterministic real-time response. ColdFire sits within the broader hierarchy of microcontrollers -> 32-bit MCUs -> ColdFire family -> V2 core microcontrollers. It is commonly used in industrial control, factory automation, and connected-device designs where legacy 68K code can be retained while taking advantage of modern peripherals and integrated Ethernet. Key features of the MCF5281CVM66J include 256 KB flash program memory, 32 KB or more of SRAM (family-dependent), an enhanced multiply-accumulate unit (EMAC), four 32-bit timers plus a 16-bit periodic interrupt timer, eight-channel flexible 12-bit (or 10-bit family-dependent) ADC on selected variants, real-time clock with 32 kHz crystal support, and a low-voltage detect / power-on reset supervisor. The integrated Fast Ethernet controller with media-independent interface (MII) eliminates the need for an external MAC chip, reducing BOM cost and PCB area in connected industrial nodes. The ColdFire V2 core uses a variable-length RISC-like encoding derived from the Motorola 68000, executing most instructions in a single cycle and providing deterministic interrupt latency suitable for hard real-time control loops. The peripheral set is connected via an enhanced time-multiplexed bus, allowing DMA-driven data movement between Ethernet, CAN, and on-chip RAM with minimal CPU overhead. Typical applications include industrial Ethernet nodes (PROFINET, EtherNet/IP, Modbus TCP), CAN-based motor controllers and servo drives, building-automation gateways, point-of-sale terminals, and embedded web servers. The combination of 66 MHz performance, on-chip Ethernet MAC, and CAN is particularly well suited to factory-floor devices that must bridge fieldbus and enterprise networks. When designing with this part, ensure the 256-MAPBGA land pattern matches the JEDEC MS-034 package outline and that the four-layer PCB stack-up meets the impedance requirements for the MII Ethernet signals. Decoupling must include a 0.1 µF ceramic capacitor per logic supply pin plus bulk tantalum or polymer capacitors near the package.

MCF5281CVM80 - 80MHz ColdFire V2 MCU 256KB Flash | NXP

The NXP Semiconductors MCF5281CVM80 is a 32-bit ColdFire V2 microcontroller running at 80 MHz, integrating 256 KB of program flash and 64 KB of SRAM in a 256-ball MAP-BGA (17x17 mm) package. The part combines an Ethernet MAC, CAN module, and a rich set of serial peripherals (UART, I²C, SPI) on-chip, targeting industrial networked-embedded applications. Its 142 user I/O pins and external bus interface provide flexibility for legacy 8/16-bit memory glue logic alongside modern peripheral expansion. A ColdFire V2 microcontroller is a 32-bit RISC-style processor derived from the original Motorola 68000 instruction set architecture. ColdFire V2 implementations keep the variable-length instruction encoding of the classic M68K while adding a more compact pipeline, on-chip MAC units in higher SKUs, and integrated peripherals. Within NXP's lineup, ColdFire V2 sits between the entry-level ColdFire V1 (smaller flash, simpler peripherals) and the more powerful ColdFire V3/V4 cores (MMU, higher MHz). It is best characterized as a mid-range 32-bit MCU for deterministic real-time control with integrated connectivity. Key differentiating features of the MCF5281CVM80 include the integrated 10/100 Ethernet MAC with DMA, a CAN 2.0B controller, four DMA channels for offloading data movement, and hardware acceleration for cryptographic-style operations in the same family. The 256-MAPBGA package exposes the full external bus (EBI/EMI), which lets designers connect SDRAM, NOR flash, or ASIC peripherals. Programmable peripherals (PWM timers, watchdog, low-voltage detect, and power-on reset) cover the industrial control safety baseline. Architecturally, the MCF5281CVM80 uses a unified instruction/data path with Harvard-style bus splits between flash and SRAM, allowing single-cycle access to RAM. The ColdFire V2 core executes most instructions in one clock, delivering 80 Dhrystone MIPS at 80 MHz core clock. The on-chip voltage regulator generates 1.3-1.5 V internal logic from an external 3.3 V supply, simplifying board power design. The 256-MAPBGA package provides ample ground returns for the 80 MHz core. Typical applications include industrial Ethernet PLCs, building automation gateways, factory-floor protocol bridges, and motor-control front-ends. Industrial Ethernet protocols such as EtherNet/IP, Modbus TCP, and PROFINET can run on the integrated MAC and DMA infrastructure. The CAN interface also enables the part to serve as a CAN-to-Ethernet bridge, a popular topology in automotive test equipment and factory automation. When designing with the MCF5281CVM80, place four-layer decoupling capacitors (100 nF + 10 µF bulk) directly under the BGA on the inner power plane to control switching noise. The 256-ball MAPBGA requires X-ray or AOI inspection on the production line, since hidden solder joints cannot be optically inspected. Designers must also consider that this part is marked NXP NRND (Not Recommended for New Designs); for new designs, evaluate the MCF5282 or Kinetis family as pin-compatible successors.

MCF5282CVF66 - ColdFire V2 32-bit MCU, 512KB Flash, 66MHz | NXP

The NXP Semiconductors MCF5282CVF66 is a 32-bit ColdFire V2 microcontroller (MCU) with 512KB on-chip Flash and 64KB SRAM, running at 66 MHz in a 256-pin MAPBGA (17x17 mm) package, integrating 10/100 Ethernet MAC, CAN 2.0, and a rich peripheral set for networked embedded designs. ColdFire V2 microcontrollers are 32-bit RISC processors derived from the original Motorola 68000 instruction set architecture. Positioned between 8/16-bit legacy MCUs and higher-end ColdFire V3/V4 parts, the V2 core delivers single-cycle MAC (multiply-accumulate) instructions, hardware divide, and deterministic interrupt response, while keeping silicon area and power consumption lower than ARM Cortex-M3 equivalents from the same era. MCF5282CVF66 belongs to the MCF528x family, which is designed to simplify embedded Ethernet-networked MCU applications by combining the ColdFire core with industry-standard wired-communications peripherals on a single die. Key features include 512KB of program Flash (organized 512K x 8), 64KB of SRAM, 142 general-purpose I/O lines, 10/100 Mbps Ethernet MAC (MII/RMII), dual CAN 2.0A/B controllers, three UARTs, two I2C buses, QSPI, a 4-channel 32-bit DMA, an 8-channel 10-bit ADC, and an integrated phase-locked loop (PLL) for flexible clock generation. The 66 MHz core frequency provides 56 Dhrystone MIPS of integer throughput, sufficient for protocol stacks, supervisory control loops, and basic HMI tasks. Architecture depth: the ColdFire V2 core uses a variable-length instruction pipeline and Harvard-style bus structure with separate Flash and SRAM buses, so instruction fetches and data accesses do not contend for the same bus. The on-chip voltage regulator generates the 1.5V core logic from a single 3.3V external supply, simplifying PCB power design. The MAPBGA-256 package exposes a 17x17 mm footprint with 1.0 mm ball pitch and is rated for the standard 0 to 70C commercial operating range for this part suffix (V = -40 to +85C not used here; this part is the C commercial variant). Typical applications include industrial Ethernet gateways, factory automation PLCs, building-automation controllers, CAN-bridge / CAN-Ethernet converters, point-of-sale terminals, and embedded web servers. The integrated Ethernet and CAN peripherals make it especially suited to bridging legacy serial or CAN-based field devices onto TCP/IP networks. Design consideration: the 256-ball MAPBGA requires 4-layer (or preferably 6-layer) PCB stack-up with laser-drilled or via-in-pad microvias for reliable assembly; routing fan-out below the package is non-trivial and should be evaluated using the manufacturer's reference layout. The part operates from a single 3.3V rail; on-chip LDO generates the 1.5V core supply.

The NXP MCF5282CVF66J is a 32-bit ColdFire V2 microcontroller from the MCF528x family with 512KB of Flash memory, a 66 MHz core clock, and integrated 10/100 Ethernet plus CAN peripherals, housed in a 256-ball MAPBGA (17x17 mm) package. It addresses embedded networked control applications that need deterministic performance, on-chip Flash, and rich connectivity while keeping PCB area compact. A ColdFire microcontroller is a 32-bit RISC-style processor core derived from the legacy Motorola 68000 family and now maintained by NXP. Within the MCU hierarchy, ColdFire sits between traditional 8/16-bit controllers and high-performance ARM Cortex-M cores, targeting connected industrial nodes where deterministic interrupt response, on-chip Ethernet/CAN, and moderate code density matter more than raw Dhrystone throughput. The MCF528x line specifically simplifies embedded Ethernet-networked MCU designs by integrating MAC, CAN, multiple UARTs, QSPI, I2C, DMA, timers, and PWM on a single die. Key features include an integrated 10/100 Ethernet MAC supporting MII/RMII PHYs, a CAN 2.0B controller for industrial fieldbus, four DMA channels, a low-voltage detector with power-on reset, a watchdog timer, eight PWM channels, and 150 general-purpose I/Os. The 66 MHz V2 core delivers roughly 56 MIPS and supports JTAG/BDM for debug. The 256-MAPBGA provides generous I/O for an industrial gateway or motor-control front-end while still being hand-solderable with proper reflow profile. The internal bus architecture uses crossbar-style arbitration between the core, DMA, and peripheral bridges, allowing sustained Ethernet throughput without starving interrupt-driven code. The Flash interface includes a hardware-accelerated program/erase state machine, offloading Flash management from firmware and reducing code size overhead. Typical applications include industrial Ethernet gateways, building automation controllers, CAN-based motor nodes, remote telemetry units, and HVAC control boards. The combination of Ethernet, CAN, and 150 GPIO allows the same part to act as a master controller, removing the need for a companion bridge chip. Consider power-supply decoupling carefully - the 3.3V core and I/O rails should be bypassed with 100 nF ceramics per supply pin and bulk capacitance local to the BGA. Software should enable the watchdog early and use the DMA engine for sustained I/O to keep interrupt latency predictable.

MCF5282CVM80J - 32-Bit ColdFire V2 MCU 512KB Flash | NXP

The NXP Semiconductors MCF5282CVM80J is a 32-bit ColdFire V2 microcontroller unit (MCU) integrating 512 KB of flash memory, 64 KB of RAM, and a 10/100 Ethernet MAC in a 256-ball MAPBGA package. Operating at 80 MHz, this ColdFire V2 core variant targets embedded Ethernet-networked MCU applications that require deterministic real-time performance and rich connectivity peripherals. A ColdFire V2 microcontroller is a member of the 32-bit microcontroller family based on the Freescale/NXP ColdFire instruction set architecture, a reduced instruction set computing (RISC) derivative of the Motorola 68000 family. Positioned within the broader taxonomy, ColdFire V2 -> 32-bit MCU -> microcontroller -> embedded processor -> semiconductor, this device class simplifies embedded Ethernet-networked designs by integrating networking peripherals with general-purpose I/O, DMA, and memory interfaces on a single die. Key features include 150 general-purpose I/O lines, a ColdFire V2 core with up to 80 MHz operation, 512 KB on-chip flash program memory, 64 KB on-chip SRAM, an integrated 10/100 Mbps Ethernet MAC with Media Independent Interface (MII), two CAN 2.0B controllers, three UART/USART ports, a queued SPI module, and an I2C bus interface. Additional peripherals include DMA channels, PWM outputs, a low-voltage detect (LVD) module, a power-on reset (POR), and a watchdog timer. The architecture uses a Harvard-style memory bus with a ColdFire V2 enhanced multiply-accumulate (EMAC) unit, achieving 80 Dhrystone 2.1 MIPS at 80 MHz while maintaining code density advantages over ARM7. The MAPBGA-256 package supports high-pin-count peripheral multiplexing across external bus interfaces, EBI/EMI, and SDRAM controller signals. Typical applications include industrial Ethernet gateways, building automation controllers, point-of-sale terminals, networked sensor hubs, and CAN/Ethernet bridges. The integrated Ethernet MAC with MII allows direct connection to a PHY such as the KSZ8041, while the dual CAN controllers suit automotive and industrial Control Area Network backbones. When designing with this device, ensure the MAPBGA-256 PCB land pattern uses 1.0 mm pitch balls with proper microvia or via-in-pad construction, since high-speed Ethernet signals require controlled impedance traces. The external bus interface supports glueless connection to SDRAM and flash; adding a 32 kHz external crystal is required for the real-time clock and timing reference. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, providing engineers with a consolidated reference for sourcing and second-sourcing decisions.

MCF53010CQT240

MCF53010CQT240 - 240MHz ColdFire V3 MPU, 208-TQFP | NXP

The NXP MCF53010CQT240 is a 32-bit ColdFire V3 microprocessor (MPU) running at 240 MHz, delivering up to 211 Dhrystone 2.1 MIPS, and housed in a 208-pin LQFP/TQFP package (28x28 mm). It is part of the MCF5301x family, combining low power consumption, high integration, and connectivity peripherals with a voice codec block, making it well suited for industrial control with embedded voice applications. A microprocessor (MPU) like the ColdFire MCF5301x is a CPU-centric integrated circuit that typically requires external memory (SRAM/SDRAM/Flash) for program and data storage. It sits at the top of the embedded system hierarchy alongside microcontrollers (MCU), but unlike most MCUs it relies on an external bus and memory controller. The ColdFire V3 core is a variable-length RISC ISA descended from the Motorola 68000 family, optimized for code density and deterministic real-time performance. Key features of the MCF53010CQT240 include an integrated Enhanced Multiply-Accumulate (EMAC) unit, 16 KBytes of unified instruction/data cache, 128 KBytes of internal SRAM, a 32-bit SDRAM/DDR controller, a 10/100 Ethernet MAC, USB 2.0 Full-Speed OTG, CAN, I2C, SPI, UARTs, and an on-chip voice codec with amplifiers. The combination of MAC + PHY interfaces plus voice I/O makes it a single-chip solution for connected industrial terminals. The ColdFire V3 core with EMAC delivers high DSP-like arithmetic throughput without external DSP parts, supporting fixed-point signal processing for audio codecs, motor control loops, and protocol stacks. Operating voltage is 3.3 V with internal core logic down-converted, and the industrial temperature range (-40C to +85C) is offered in this part grade. Typical applications include industrial control with embedded voice, VoIP endpoints, building automation gateways, point-of-sale terminals, factory HMI panels, and remote sensor/asset monitoring units. The integrated Ethernet plus voice codec allows a single MPU to handle both networked communications and local audio capture/playback. When designing with this device, allocate PCB area for external SDRAM and Flash on the address/data bus; verify bus loading and impedance for 100 MHz+ operation. Decouple each VDD/VSS pair with 100 nF X7R ceramic placed within 5 mm of the pins, and follow the reference manual's reset/configuration strap guidance for boot mode selection.
