MCF54450VM240 개요
A microprocessor (MPU) is the central computing engine of an embedded system, executing application code and coordinating peripherals. Within the power-management and processing hierarchy, an MPU such as this sits above microcontrollers (MCUs): it offers higher clock rates, external memory buses, and richer connectivity but requires external program memory. The MCF5445x family targets power-conscious embedded control designs that need high performance and connectivity in a single highly integrated device.
Key features include the version 4 ColdFire core with an integrated MMU (memory management unit) and EMAC (enhanced multiply-accumulate unit), delivering up to 410 Dhrystone 2.1 MIPS at the family's top speed grade. The device integrates a rich peripheral set: 10/100 Ethernet, USB On-The-Go (USB OTG), PCI, I2C, SPI, SSI, and UART/USART, plus DMA and watchdog timer (WDT) peripherals.
Technically, the MCF54450 combines the superscalar-capable V4 core with separate instruction and data caches, allowing deterministic code execution from SRAM while cached code runs from external SDRAM. The 132 general-purpose I/O lines provide flexible board-level interfacing, and the ROMless memory architecture lets designers select their own flash density and update firmware in the field.
Typical applications include industrial embedded control, networked consumer devices, and power-conscious systems requiring Ethernet, USB OTG, and PCI connectivity simultaneously.
Note that NXP has designated this part NRND (Not Recommended for New Designs); new designs should evaluate successor architectures, while existing designs can continue procurement.

일반적인 애플리케이션
MCF54450VM240 적합 용도: 6 애플리케이션s: Industrial Embedded Control, Networked Consumer and Connectivity Devices, PCI-Based Expansion and Gateways, Legacy Board Maintenance and Continuity, Medical Instrumentation Control Modules, Building Automation and Security Controllers.
Industrial Embedded Control
The MCF54450VM240 fits industrial embedded controllers where 240 MHz of ColdFire V4 processing, 132 I/O lines, and integrated Ethernet, CAN-class serial links (UART/SPI/I2C), and DMA enable deterministic control loops plus networked supervision in one chip. Its MMU supports structured firmware with protected memory regions, while the 32 KB SRAM serves time-critical routines and DMA buffers. The 256-MAPBGA (17x17 mm) keeps board area compact for DIN-rail and panel controllers. Because the part is NRND, new industrial designs should treat it as a legacy-maintenance solution and plan migration.
추천
Networked Consumer and Connectivity Devices
Consumer devices needing simultaneous 10/100 Ethernet and USB OTG benefit directly from the MCF54450VM240's integrated connectivity MACs, which reduce BOM cost versus external controller chips. The 240 MHz V4 core with separate 16 KB instruction and data caches sustains protocol stacks (TCP/IP, USB device classes) with headroom for application logic. Power-conscious design targets - a stated family goal - suit battery-adjacent and always-on consumer products. The ROMless architecture lets OEMs size external flash per product tier, sharing one PCB across SKUs.
추천
PCI-Based Expansion and Gateways
With an integrated PCI controller, the MCF54450VM240 addresses gateway and expansion-card applications that must bridge PCI backplanes to Ethernet or USB. The 240 MHz core and EMAC accelerate protocol translation and data marshaling, while DMA offloads bulk transfers between PCI, Ethernet, and SDRAM. Typical implementations pair the MPU with external SDRAM on the memory bus and use the 132 I/O for status and control. This PCI capability is the MCF54450's differentiator over the MCF54451 variant, which omits it.
추천
Legacy Board Maintenance and Continuity
For products already designed around the MCF5445x family, the MCF54450VM240 and its drop-in variants (MCF54450VM240J extended temperature, MCF54452VR266 speed grade) allow continued production without PCB redesign since all share the 256-MAPBGA footprint. Procurement teams should secure last-time-buy quantities given NRND status, and verify firmware compatibility across speed grades - the family's common core ensures binary compatibility. Heisener reported 6,696 pieces in stock as of 2026-10-18, but NRND inventory fluctuates.
추천
Medical Instrumentation Control Modules
Benchtop medical instruments and patient-data terminals use the MCF54450VM240's Ethernet port for networked data upload, USB OTG for peripherals such as barcode scanners and flash drives, and UART/SSI for sensor front ends. The MMU supports multi-process firmware architectures separating measurement, UI, and communication tasks. The 240 MHz core comfortably runs HMI frameworks alongside acquisition code. Note: for new medical designs, NRND status makes this part a legacy-only choice; validated existing platforms can continue with drop-in J-grade variants.
추천
Building Automation and Security Controllers
Security panels and building-automation controllers leverage the MCF54450VM240's multiple UART/USARTs for RS-485 field buses, SPI/I2C for sensor and RTC peripherals, and Ethernet for head-end reporting. The 132 GPIO lines drive keypads, relays, and zone inputs directly, reducing external logic. The 16 KB data cache plus 32 KB SRAM support fast event handling, while DMA sustains concurrent bus traffic. As with other applications, its NRND status positions this MPU for sustaining existing controller platforms rather than new development.

설계 노트
The 256-ball MAPBGA (17x17 mm) with fine ball pitch requires a multilayer PCB (minimum 6 layers recommended) with dedicated power and ground planes. Escape routing from the inner ball rows needs via-in-pad or buried-via fanout. Follow NXP MCF5445x hardware design guidance: keep the 1.5V core rail and 3.3V I/O rail regions separated, and place decoupling capacitors (100 nF per power ball pair plus bulk capacitance) directly under the BGA on the opposite board side.
Estimated: as a ROMless MPU the MCF54450VM240 executes from external SDRAM - size the power supply for core plus I/O plus SDRAM termination current, not just the chip alone. Use the datasheet power tables for the 240 MHz grade and add SDRAM active/termination current. Because the part is NRND, confirm absolute maximum ratings and power figures against the latest MCF5445x datasheet revision on nxp.com before finalizing the regulator design.
Boot configuration pins select the boot source (external flash width, boot location) and are latched at reset - verify strap resistor values against the MCF5445x datasheet boot configuration table. Migrating from MCF54450 to MCF54451 saves cost but drops PCI; confirm no firmware dependency before swapping. Finally, plan lifecycle risk mitigation now: NRND parts face last-time-buy announcements, so qualify MCF54452VR266 or J-grade stock and hold safety inventory.
