MCF5474VR266 Visão geral
A microprocessor unit (MPU) is the central computing engine of an embedded system, sitting above microcontrollers in the hierarchy by offering higher clock speeds, external memory interfaces, and richer peripherals while requiring external program memory. The ColdFire V4e architecture is an enhanced 32-bit RISC-derived CISC-compatible core that adds a memory management unit (MMU) and a floating-point unit (FPU) directly on the core, enabling running of high-level operating systems such as Linux.
Key features of the MCF5474VR266 include the 266 MHz V4e core with hardware divide, MMU, and FPU; dual Ethernet media access controllers (MACs) for redundant or dual-port networking; a PCI controller for host/expansion connectivity; a hardware encryption accelerator supporting secure communications; and multiple serial interfaces including USB, I2C, UART, and DMA-capable serial peripherals.
Architecturally, the device couples the ColdFire V4e execution core with a system bus that services the on-chip peripherals and an external bus interface, allowing ROMless operation where boot code and applications are fetched from external flash or SDRAM. The ROMless design (denoted by the V in the part number suffix) gives system designers full control of code storage, which suits scalable networking products. The hardware encryption accelerator offloads DES/3DES/AES-class operations from the core, sustaining line-rate secure throughput in network control planes.
Typical applications include industrial Ethernet switches and gateways, networked building and process control, print and imaging systems, and secure remote-management nodes where dual Ethernet plus PCI and cryptographic acceleration are required.
A key design consideration is supply architecture: the MCF5474VR266 operates from dual 2.5V (core) and 3.3V (I/O) rails, so a proper power-sequencing and decoupling plan is required. Thermal design should also budget for the power dissipated by the 266 MHz core in the 27 x 27 mm PBGA.

Aplicações típicas
MCF5474VR266 é adequado para 6 aplicaçãos: Industrial Ethernet Switches and Gateways, Networked Building and Process Control, Secure Remote-Management Nodes, Print and Imaging Systems, Test and Measurement Instrument Control, Medical Networked Monitoring Equipment.
Industrial Ethernet Switches and Gateways
The MCF5474VR266 fits industrial Ethernet switching because it integrates two independent 10/100 Ethernet MACs plus a PCI controller on one die, letting a single 266 MHz ColdFire V4e core manage switch fabric control, protocol stacks, and management interfaces concurrently. In a gateway topology, one Ethernet port faces the plant floor network (Modbus TCP, EtherNet/IP) while the second port connects upward to supervisory systems, removing the need for an external second MAC chip. The ROMless external-bus design allows flash capacity to scale with protocol feature sets. The hardware encryption accelerator secures remote-management sessions at line-rate without stealing core cycles, a quantified benefit for always-on TLS/SSH endpoints in factory networks.
Recomendado
Networked Building and Process Control
For building automation and process controllers, the MCF5474VR266 provides an MMU-equipped 266 MHz core that can run embedded Linux with multiple protocol daemons while the dual Ethernet MACs partition control traffic from management traffic physically at the silicon level. The FPU accelerates PID loop math and sensor scaling without software emulation, improving worst-case loop determinism. Its PCI interface accepts off-the-shelf fieldbus or data-acquisition expansion cards, and the DMA-capable serial peripherals move ADC or I/O data with minimal CPU overhead. Because the part is ROMless, OEMs control firmware entirely from external flash, easing field-update strategy. In these cost-sensitive, long-lifecycle products, the NRND status should be mitigated with a last-time-buy of the 266 MHz grade or a pin-compatible MCF548x migration.
Recomendado
Secure Remote-Management Nodes
The dedicated encryption accelerator makes the MCF5474VR266 well suited to secure remote management appliances - out-of-band console servers, VPN termination nodes, and secure telemetry gateways. AES/DES-class offload sustains encrypted tunnels while the 266 MHz V4e core simultaneously serves web management interfaces over the second Ethernet port, achieving secure and plaintext traffic handling on one device. The MMU enables memory-protected Linux, isolating management daemons from data-plane code for security hardening. Dual 2.5V/3.3V supply rails keep the power design simple relative to multi-rail SoCs. Since lifecycle status is NRND, secure-design teams should pair existing designs with a documented replacement plan using pin-compatible MCF5475VR266 or MCF548x parts before authorized stock depletes.
Recomendado
Print and Imaging Systems
Print engines, MFP controllers, and imaging peripherals historically favored the MCF547x family for its combination of PCI, USB, Ethernet, and general-purpose serial peripherals on a single 266 MHz CPU. The V4e core handles raster processing and job scheduling; PCI connects the video/marker interface ASIC; USB serves job submission and configuration; and the Ethernet MACs integrate the device into office networks. The MMU allows a Linux-based print stack with separate processes for spooling and rendering, and the FPU accelerates color-conversion math. With 388 balls in a 27 x 27 mm PBGA, the footprint consolidates board area versus multi-chip CPU-plus-MAC solutions. Existing imaging OEMs should verify drop-in alternatives in the MCF547x family as this grade approaches end-of-life.
Recomendado
Test and Measurement Instrument Control
In instruments such as protocol analyzers, network test sets, and industrial data loggers, the MCF5474VR266 serves as the system controller: the 266 MHz MMU-equipped core runs the user interface and instrument firmware (often embedded Linux), PCI hosts measurement or capture hardware, dual Ethernet MACs provide control plus dedicated data ports, and the FPU accelerates calibration and DSP-adjacent math. The DMA-driven serial peripherals stream sampled data to external SDRAM without core intervention, protecting real-time capture performance. The ROMless architecture lets instrument OEMs size firmware flash per model tier from one PCB. Because the part is NRND, new instrument platforms should target the pin-compatible MCF548x family instead, while service and legacy-product lines can draw from remaining authorized stock.
Recomendado
Medical Networked Monitoring Equipment
Networked medical monitors and lab instrumentation use the MCF5474VR266 where dependable connectivity and memory protection are mandatory: the MMU isolates measurement firmware from networking stacks, supporting reliability requirements in multi-tenant systems, while dual Ethernet MACs enable physical separation of clinical network segments. The 266 MHz V4e core provides ample margin for protocol processing and data export, and the hardware encryption accelerator supports secure transmission requirements in patient-data telemetry. PCI accepts acquisition daughter boards, and the FPU accelerates filter and trend algorithms. Design teams in this regulated space should note the NRND status and qualify the pin-compatible MCF5475VR266 (same speed, same package) as a continuity source, since requalification cost is minimal for an identical-footprint, same-family swap.

Notas de projeto
The MCF5474VR266 requires two supply rails: approximately 2.5V for the ColdFire V4e core and 3.3V for I/O. Verify the exact rail order in the MCF547x family hardware design guide before committing to a power tree, and add bulk plus 0.1uF decoupling at every ball-group via field. Estimated: a 266 MHz V4e drawing on the order of 0.5-1 W total (input values: typical ColdFire V4e dynamic current at 266 MHz plus I/O loading) demands a low-ESR 2.5V regulator with at least 20-30% margin over worst-case core current.
The 27 x 27 mm, 388-ball PBGA typically uses 1.0 mm ball pitch with standard 0.5 mm pad, dog-bone or via-in-pad fanout. Plan at least four signal layers plus two power/ground planes; dedicate a solid ground plane under the BGA for signal return. Route DDR-class external memory (SDRAM on the external bus interface) with matched lengths per the MCF547x hardware specifications, and keep PCI stubs short to preserve signal integrity at the bus clock.
This part is ROMless: it cannot execute without external flash or boot device, so a blank-board power-up will simply hang at the boot strap. Also, because the device is NRND, avoid new designs on this exact MPN - design to the pin-compatible MCF548x family instead, or secure last-time-buy stock. Finally, do not assume MCF5474 and MCF5475 peripheral sets are identical; confirm the peripheral differences in the family reference manual before dropping one in for the other.
