NXP Semiconductors MCF54451CVM180

Overview

MCF54451CVM180 from NXP Semiconductors is a ColdFire® Version 4 microprocessor with MMU and EMAC, operating at up to 180 MHz core clock, featuring 16-KB instruction cache, 16-KB data cache, 32-KB on-chip SRAM, and dual 10/100 Ethernet MACs. It targets industrial networking gateways requiring deterministic real-time control, secure boot from SPI flash, and concurrent peripheral access via crossbar switch.

For engineers reviewing the MCF54451CVM180 datasheet, MCF54451CVM180 pinout, MCF54451CVM180 application, or MCF54451CVM180 equivalent, key selection criteria include its 256-pin MAPBGA package, 180 MHz performance ceiling, -40°C to +85°C industrial temperature grade, DDR SDRAM controller support, and integrated cryptography acceleration unit (CAU) for AES/SHA-1 offload.

Technical Context

The MCF54451CVM180 implements the ColdFire V4 core with hardware memory management unit (MMU), enabling full POSIX-compliant OS support such as Linux or VxWorks. Its crossbar switch (XBS) allows simultaneous access to SRAM, peripherals, and DDR controller by multiple bus masters including CPU, DMA, and PCI.

It integrates a 16-channel DMA controller, USB 2.0 On-the-Go with ULPI interface, 32-bit PCI controller, ATA/ATAPI host interface, and two independent Fast Ethernet controllers compliant with IEEE 802.3. The CAU coprocessor accelerates DES/3DES/AES encryption and MD5/SHA-1 hashing without CPU intervention.

FAQ

What is the maximum operating frequency of the MCF54451CVM180?

The MCF54451CVM180 operates at a maximum core clock frequency of 180 MHz, as specified in its ordering information and validated across the full industrial temperature range (-40°C to +85°C). This speed grade is confirmed in Table 2 of the MCF5445x datasheet Rev. 9, and is distinct from higher-speed variants like the MCF54455VP266. The MCF54451CVM180 delivers up to 370 Dhrystone 2.1 MIPS at this frequency.

Does the MCF54451CVM180 include a hardware cryptography accelerator?

Yes, the MCF54451CVM180 includes a Cryptography Acceleration Unit (CAU) that supports DES, 3DES, AES (128/192/256-bit), MD5, and SHA-1 algorithms. This is explicitly listed in the MCF5445x Family Comparison table (Table 1) where MCF54451 is marked with "•" under the CAU row - confirming CAU presence unlike the base MCF54450 variant.

What package type and dimensions does the MCF54451CVM180 use?

The MCF54451CVM180 uses a 256-ball MAPBGA package measuring 17 mm × 17 mm with 1.0 mm ball pitch. This is confirmed in the "Ordering Information" section (Table 2) and the "Pinout-256 MAPBGA" diagram (Figure 5) of the MCF5445x datasheet Rev. 9. It shares this package with the MCF54450, distinguishing it from the 360-ball TEPBGA used by MCF54452–MCF54455.

How many Ethernet MACs does the MCF54451CVM180 integrate?

The MCF54451CVM180 integrates two independent 10/100 Fast Ethernet MACs (FEC0 and FEC1), as verified in the MCF5445x Family Comparison table (Table 1) and the block diagram (Figure 1). Both MACs support MII and RMII modes, and their dedicated pin groups (e.g., FEC0_RXD[3:0], FEC1_TXEN) are fully mapped in the 256 MAPBGA pinout (Figure 5).

Is the MCF54451CVM180 supported for booting from serial flash devices?

Yes, the MCF54451CVM180 supports booting from SPI-compatible flash, EEPROM, and FRAM devices - a feature explicitly listed in the "Features" section of the MCF5445x datasheet Rev. 9. This capability is enabled via the Serial Boot Facility (SBF) and is functionally identical across all MCF5445x variants, including the MCF54451CVM180.
