Product details
Overview
MCF54450VM240J from NXP Semiconductors is a ColdFire® Version 4 microprocessor with MMU and EMAC, operating at up to 240 MHz core clock, delivering up to 370 Dhrystone 2.1 MIPS, featuring 16-KB instruction cache, 16-KB data cache, and 32-KB on-chip SRAM. It targets industrial networking gateways requiring deterministic real-time Ethernet, secure boot from SPI flash, and DDR SDRAM interfacing.
For engineers reviewing the MCF54450VM240J datasheet, MCF54450VM240J pinout, MCF54450VM240J application, or MCF54450VM240J equivalent, key selection criteria include its 256-pin MAPBGA package, dual Fast Ethernet MAC support, USB 2.0 OTG with ULPI, and integrated cryptography acceleration unit (CAU) for AES/SHA-1 offload in edge security applications.
Technical Context
The MCF54450VM240J implements a superscalar ColdFire V4 core with memory management unit (MMU) and enhanced multiply-accumulate (EMAC) unit, enabling full Linux OS support and real-time signal processing. Its crossbar switch (XBS) architecture allows concurrent access to peripherals and SRAM by multiple bus masters including DMA, PCI, and FlexBus controllers.
It integrates a 16-channel DMA controller, 16-bit 133-MHz DDR/mobile-DDR/DDR2 SDRAM controller, two 10/100 Fast Ethernet MACs with RMII/MII support, and a coprocessor for DES/3DES/AES/MD5/SHA-1 acceleration - all synchronized via a phase-locked loop (PLL) with programmable dividers and independent oscillator domains for core, I/O, and SDRAM supplies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCF54451VM240 | Same 256 MAPBGA package and 240 MHz speed grade, but rated for –40°C to +85°C industrial temperature range vs. MCF54450VM240J's 0°C to +70°C. | Required for extended-temperature deployments (e.g., outdoor base stations, automotive under-hood). | Select MCF54451VM240 when ambient operating temperature exceeds 70°C or requires industrial-grade qualification. |
| MCF54452VP266 | 360-ball TEPBGA package, 266 MHz core clock, adds PCI controller and ATA interface - physically incompatible pinout and larger footprint. | Suitable for higher-performance designs needing PCI expansion (e.g., add-in cards) or legacy ATA storage interfaces. | Choose MCF54452VP266 only if PCI/ATA functionality is required and board redesign for 23 mm × 23 mm package is feasible. |
Compared with MCF54450VM240J, MCF54451VM240 offers identical performance in a wider temperature grade without layout change, while MCF54452VP266 trades pin compatibility for higher clock speed and added peripherals - making it a platform upgrade rather than a drop-in alternative.

FAQ
What is the maximum operating frequency of the MCF54450VM240J?
The MCF54450VM240J operates at a maximum core clock frequency of 240 MHz, delivering up to 370 Dhrystone 2.1 MIPS. This speed grade is validated across the specified commercial temperature range (0°C to +70°C), with timing margins confirmed per the Rev. 9 datasheet's clock timing specifications and PLL configuration guidelines.
Does the MCF54450VM240J support DDR2 memory?
Yes, the MCF54450VM240J includes a 16-bit 133-MHz DDR/mobile-DDR/DDR2 controller. It supports DDR2-266 (133 MHz clock) with configurable CAS latency, burst length, and refresh timing - verified in the Electrical Characteristics section (Section 5.8) and Hardware Design Considerations (Section 3.3) of the MCF5445x datasheet.
What package type and dimensions does the MCF54450VM240J use?
The MCF54450VM240J uses a 256-ball MAPBGA package measuring 17 mm × 17 mm with 1.0 mm ball pitch. Pin assignments match the MCF54450/MCF54451 256 MAPBGA layout shown in Figure 5 of the datasheet, and thermal pad exposure is specified per NXP's package drawing documentation.
How many Ethernet MACs does the MCF54450VM240J integrate?
The MCF54450VM240J integrates two independent 10/100 Fast Ethernet MACs (FEC0 and FEC1), each supporting MII and RMII physical layer interfaces. Both MACs are fully functional in the MCF54450 variant, as confirmed in Table 1 (Family Comparison) and the block diagram (Figure 1) of the MCF5445x datasheet.
Is the cryptography acceleration unit (CAU) present in the MCF54450VM240J?
No, the CAU is not included in the MCF54450VM240J. According to Table 1 (MCF5445x Family Configurations), the Cryptography Acceleration Unit (CAU) is only available in MCF54451, MCF54453, and MCF54455 variants - not in MCF54450 or MCF54452. The MCF54450VM240J relies on software-based crypto or external accelerators.
