Product details
Overview
MCF54452VP266R from NXP Semiconductors is a ColdFire® Version 4 microprocessor with MMU and EMAC, operating at 266 MHz core clock, delivering up to 410 Dhrystone 2.1 MIPS. It integrates 16-KB instruction cache, 16-KB data cache, 32-KB SRAM, dual 10/100 Ethernet MACs, USB 2.0 OTG with ULPI, and a 32-bit PCI controller - deployed in industrial networking gateways and secure edge routers.
For engineers reviewing the MCF54452VP266R datasheet, MCF54452VP266R pinout, MCF54452VP266R application, or MCF54452VP266R equivalent, key selection considerations include DDR2/DDR/mobile-DDR memory controller timing, PCI bus arbitration behavior, cold boot from SPI flash, and cryptographic acceleration unit (CAU) support for AES/SHA-1 offload in resource-constrained embedded systems.
Technical Context
The MCF54452VP266R implements a superscalar ColdFire V4 core with integrated MMU for full virtual memory management and an enhanced multiply-accumulate (EMAC) unit optimized for real-time signal processing. Its crossbar switch (XBS) enables concurrent access to peripherals and RAM by multiple bus masters including CPU, DMA, and PCI.
It supports flexible boot sources (SPI flash, EEPROM, FRAM), features a 16-channel DMA controller with timer-triggered transfers, and includes dedicated hardware accelerators: CAU for DES/3DES/AES/MD5/SHA-1 and RNG for cryptographically secure entropy - all operating independently of the main CPU pipeline.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCF54455VP266 | Includes ATA/ATAPI controller and PCI support enabled by default; identical core, cache, and peripheral set otherwise. | Targeted at storage-integrated gateways requiring IDE hard drive or CompactFlash attachment. | Select MCF54455VP266 only if ATA interface is required; MCF54452VP266R offers identical performance with lower pin-count routing complexity. |
| i.MX283 | ARM926EJ-S core @ 454 MHz, integrated LCD controller and NAND flash controller; lacks PCI and CAU but adds security boot ROM. | Better suited for HMI-rich, media-enabled edge devices where display output and secure boot outweigh PCI/CAU needs. | Choose i.MX283 when prioritizing multimedia support and secure boot over hardware crypto acceleration and PCI expansion capability. |
Compared with MCF54455VP266, MCF54452VP266R removes ATA functionality to reduce package I/O count and simplify layout, while retaining full PCI, dual Ethernet, and CAU capabilities; versus i.MX283, it trades ARM ecosystem advantages for deterministic ColdFire real-time behavior and native PCI integration critical for industrial retrofit applications.

FAQ
What is the maximum supported DDR2 memory speed for the MCF54452VP266R?
The MCF54452VP266R supports a 16-bit DDR2 memory interface operating at 133 MHz clock frequency, enabling peak theoretical bandwidth of 2.1 GB/s. This matches JEDEC-standard DDR2-266 (PC2-2100) modules with CL=2.5 timing, and requires proper board-level impedance control (50 Ω single-ended, 100 Ω differential) for reliable operation at full rate.
Does the MCF54452VP266R support booting directly from SPI flash without external logic?
Yes, the MCF54452VP266R supports native serial boot from SPI-compatible flash devices using its built-in Serial Boot Facility (SBF). The processor initializes the SPI interface automatically upon reset, reads boot code from predefined addresses, and executes it directly from internal SRAM - no external boot ROM or glue logic is required.
How many independent Ethernet MACs does the MCF54452VP266R integrate, and what PHY interfaces do they support?
The MCF54452VP266R integrates two independent 10/100 Fast Ethernet MACs (FEC0 and FEC1). Each supports MII, RMII, and ULPI PHY interfaces - allowing design flexibility to select low-cost RMII PHYs (e.g., LAN8720A) or high-integration ULPI PHYs (e.g., SMSC LAN9514) depending on board space and power constraints.
Is the cryptography acceleration unit (CAU) in the MCF54452VP266R capable of AES-256 encryption in GCM mode?
Yes, the CAU in the MCF54452VP266R supports AES-128/192/256 in ECB, CBC, CFB, OFB, and CTR modes, and includes dedicated hardware for Galois field multiplication used in GCM. While GCM authentication requires software-managed counter mode, the CAU accelerates all AES block operations and GHASH computation at hardware speed.
What is the recommended power supply sequencing for the MCF54452VP266R's IVDD, EVDD, SDVDD, and PVDD rails?
The MCF54452VP266R requires IVDD (core logic) to be powered last during startup and first during shutdown. EVDD (I/O) and SDVDD (SDRAM) may power up in any order relative to each other, but must be stable before IVDD ramps. PVDD (PLL) should track IVDD closely. All supplies must ramp at ≤50 V/ms to prevent ESD clamp activation.
