Product details
Overview
MCF54452VR266 from NXP Semiconductors is a ColdFire® Version 4 microprocessor with MMU and EMAC, operating at 266 MHz (410 Dhrystone 2.1 MIPS), featuring 16-KB instruction cache, 16-KB data cache, 32-KB internal SRAM, dual 10/100 Ethernet MACs, and a 16-channel DMA controller. It targets industrial networking gateways requiring deterministic real-time processing, secure boot from SPI flash, and concurrent peripheral access via crossbar switch.
For engineers reviewing the MCF54452VR266 datasheet, MCF54452VR266 pinout, MCF54452VR266 application, or MCF54452VR266 equivalent, key selection criteria include DDR2/DDR/mobile-DDR memory controller support, PCI 66-MHz bus compliance, USB 2.0 OTG with ULPI, cryptographic acceleration (AES/DES/SHA-1), and 360-ball TEPBGA package thermal and routing constraints.
Technical Context
The MCF54452VR266 implements a ColdFire V4 core with hardware MMU for virtual memory management and an integrated EMAC unit enabling high-throughput packet processing. Its crossbar switch (XBS) allows simultaneous access to SRAM, peripherals, and DDR controllers by multiple bus masters-including CPU, DMA, and PCI-eliminating arbitration bottlenecks in multi-threaded embedded applications.
It integrates a dedicated Cryptography Acceleration Unit (CAU) supporting DES, 3DES, AES, MD5, and SHA-1 algorithms in hardware, alongside a true random number generator (RNG) and Synchronous Serial Interface (SSI) for secure firmware updates and sensor interfacing. The device supports booting directly from SPI-compatible flash, EEPROM, or FRAM without external boot ROM.

FAQ
What is the maximum operating frequency and performance rating of the MCF54452VR266?
The MCF54452VR266 operates at a maximum core frequency of 266 MHz and delivers up to 410 Dhrystone 2.1 MIPS. This performance level is validated under specified thermal and voltage conditions per the official NXP datasheet Rev. 9 (04/2021). The MCF54452VR266 achieves this using the ColdFire Version 4 core with integrated MMU and EMAC, and its performance is sustained across temperature ranges of 0°C to +70°C.
Does the MCF54452VR266 include hardware cryptographic acceleration?
Yes, the MCF54452VR266 includes a dedicated Cryptography Acceleration Unit (CAU) that supports DES, 3DES, AES (128/192/256), MD5, and SHA-1 algorithms in hardware. This offloads cryptographic operations from the main CPU, reducing latency and improving system-level security throughput - a key differentiator from non-CAU variants like the MCF54453VP266. The CAU is fully integrated into the MCF54452VR266 silicon and requires no external co-processor.
Which package type and ball count does the MCF54452VR266 use?
The MCF54452VR266 uses a 360-ball TEPBGA package measuring 23 mm × 23 mm with 1.0-mm ball pitch. This package is shared across the MCF54452, MCF54453, MCF54454, and MCF54455 derivatives and is documented in Section 4.3 ("Pinout-360 TEPBGA") of the MCF5445x datasheet Rev. 9. Pin assignments are fully defined in Table 4 and Figure 6, confirming compatibility with standard PCB layout practices for high-density BGA routing.
How many Ethernet MACs does the MCF54452VR266 integrate, and what PHY interfaces are supported?
The MCF54452VR266 integrates two independent 10/100 Fast Ethernet MACs (FEC0 and FEC1), each supporting both MII and RMII physical layer interfaces. Each MAC includes dedicated MDIO management, full-duplex operation, and hardware-assisted checksum calculation. Signal mapping for both MACs - including RXD/TXD, MDC/MDIO, CRS/COL, and REF_CLK - is explicitly defined in Table 4 of the datasheet for the 360-TEPBGA package.
Can the MCF54452VR266 boot directly from serial flash memory?
Yes, the MCF54452VR266 supports direct booting from SPI-compatible flash, EEPROM, and FRAM devices via its serial boot facility (SBF). This capability is enabled through dedicated boot configuration pins (BOOTMOD[1:0]) and requires no external boot ROM or host processor. The boot sequence, pin multiplexing behavior, and supported command sets are fully detailed in the MCF5445x Reference Manual and Section 2 ("Ordering Information") of the datasheet.
