Product details
Overview
MCF54450AVM240 from NXP Semiconductors is a ColdFire® Version 4 microprocessor with MMU and EMAC, operating at up to 240 MHz, delivering up to 370 Dhrystone 2.1 MIPS, featuring 16-KB instruction cache, 16-KB data cache, and 32-KB on-chip SRAM. It supports booting from SPI-compatible flash/EEPROM/FRAM and integrates dual 10/100 Ethernet MACs for industrial networking applications.
For engineers reviewing the MCF54450AVM240 datasheet, MCF54450AVM240 pinout, MCF54450AVM240 application, or MCF54450AVM240 equivalent, key selection considerations include its 256-pin MAPBGA package, 240 MHz core clock, DDR SDRAM controller support, USB 2.0 OTG with ULPI, and dual FECs - all critical for real-time embedded control and communications gateway designs.
Technical Context
The MCF54450AVM240 implements a ColdFire V4 core with integrated MMU for full virtual memory management and an EMAC unit enabling high-throughput arithmetic operations. Its crossbar switch (XBS) architecture allows concurrent access to peripherals and RAM by multiple bus masters, including the 16-channel DMA controller and PCI interface.
It features a 16-bit DDR/mobile-DDR/DDR2 memory controller running at 133 MHz, two independent 10/100 Fast Ethernet controllers (FEC0/FEC1), and a cryptography acceleration unit (CAU) supporting DES, 3DES, AES, MD5, and SHA-1 - though CAU is absent in MCF54450 per family comparison table.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCF54451VM240 | Same core, package, and speed; adds Cryptography Acceleration Unit (CAU) for AES/SHA-1 offload. | Required where TLS 1.2+ or IPsec payload encryption is performed in real time. | Select MCF54451VM240 if cryptographic throughput >5 Mbps is needed without CPU load. |
| MCF54455VP266 | 360-ball TEPBGA, 266 MHz core, adds ATA/ATAPI controller and PCI interface. | Suitable for storage-integrated systems (e.g., NAS appliances) or PCI-based add-in cards. | Choose MCF54455VP266 only when ATA or PCI expansion is mandatory; otherwise, MCF54450AVM240 offers better cost/power density. |
Compared with MCF54451VM240, the MCF54450AVM240 lacks CAU but matches in core performance and package - ideal for non-crypto control tasks. Against MCF54455VP266, it trades PCI/ATA for smaller footprint and lower power, making it preferable for space-constrained edge gateways.

FAQ
What is the maximum operating frequency of the MCF54450AVM240?
The MCF54450AVM240 operates at a maximum core clock frequency of 240 MHz, delivering up to 370 Dhrystone 2.1 MIPS. This speed is guaranteed under industrial temperature conditions (0°C to +70°C) with proper power supply sequencing and thermal management per the datasheet's hardware design guidelines.
Does the MCF54450AVM240 include a cryptography acceleration unit (CAU)?
No, the MCF54450AVM240 does not include a cryptography acceleration unit. According to the MCF5445x Family Comparison table, CAU is present only in MCF54451, MCF54453, and MCF54455 variants. The MCF54450AVM240 relies on software-based crypto or external accelerators for DES, AES, or SHA-1 operations.
Which package type is used for the MCF54450AVM240?
The MCF54450AVM240 uses a 256-ball MAPBGA package measuring 17 mm × 17 mm with 1.0 mm ball pitch. This package is shared with the MCF54451 and is distinct from the 360-ball TEPBGA used by higher-end variants like MCF54452–MCF54455.
Can the MCF54450AVM240 boot directly from SPI flash memory?
Yes, the MCF54450AVM240 supports booting from SPI-compatible flash devices, as confirmed in the Features section of the datasheet. Boot mode is selected via BOOTMOD[1:0] pins, and the serial boot facility (SBF) provides configurable 1-, 2-, or 4-bit port sizes for optimal interface flexibility with common SPI NOR flash parts.
How many Ethernet MACs does the MCF54450AVM240 integrate?
The MCF54450AVM240 integrates two independent 10/100 Fast Ethernet MACs (FEC0 and FEC1), each supporting both MII and RMII physical layer interfaces. These are fully programmable, support IEEE 1588 timestamping via PIT timers, and operate concurrently without resource contention due to the crossbar switch architecture.
