Product details
Overview
MCF54452VP266 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 on-chip SRAM, dual 10/100 Ethernet MACs, and a 32-bit PCI controller. It targets network-attached industrial gateways requiring deterministic real-time control and secure connectivity.
For engineers reviewing the MCF54452VP266 datasheet, MCF54452VP266 pinout, MCF54452VP266 application, or MCF54452VP266 equivalent, key selection criteria include DDR2 memory interface timing compliance, ULPI-based USB 2.0 OTG integration, cryptographic acceleration unit (CAU) support for AES/SHA-1, and TEPBGA-360 package thermal performance in fanless embedded systems.
Technical Context
The MCF54452VP266 implements a ColdFire V4 core with hardware MMU for protected multitasking OS environments and an integrated EMAC for high-throughput packet processing. Its crossbar switch (XBS) enables concurrent access to peripherals and RAM by multiple bus masters including PCI, FlexBus, and DMA controllers.
It integrates a 16-channel DMA engine supporting scatter-gather transfers across dual FECs, USB OTG, DSPI, and SSI interfaces. The CAU offloads DES/3DES/AES/MD5/SHA-1 operations, while the random number generator supports secure boot and TLS key generation in edge gateway applications.

FAQ
What is the maximum DDR2 memory bandwidth supported by the MCF54452VP266?
The MCF54452VP266 integrates a 16-bit 133-MHz DDR2 controller capable of delivering up to 266 MB/s peak bandwidth. This is achieved using double-data-rate transfers on a 16-bit bus clocked at 133 MHz, sufficient for buffering multiple HD video streams or real-time packet inspection buffers in industrial gateways. The controller supports DDR2-266 (PC2-2100) modules with configurable CAS latency and refresh timing.
Does the MCF54452VP266 include a hardware cryptography accelerator?
No, the MCF54452VP266 does not include a Cryptography Acceleration Unit (CAU). Unlike the MCF54453VP266 and MCF54455VP266 variants, this part omits the CAU block that accelerates AES, SHA-1, MD5, DES, and 3DES operations. Applications requiring hardware crypto acceleration must select MCF54453VP266 or MCF54455VP266 instead, as the MCF54452VP266 relies on software-only implementations for cryptographic functions.
What package type and thermal characteristics apply to the MCF54452VP266?
The MCF54452VP266 uses a TEPBGA–360 package measuring 23 mm × 23 mm with 1.27 mm ball pitch. It is rated for 0°C to +70°C ambient operation and features dedicated thermal balls (VSS) and power planes (IVDD/EVDD/SDVDD) to support continuous 266 MHz operation in fanless enclosures. Thermal resistance (θJA) is 22°C/W typical under JEDEC JESD51-7 conditions with 2-layer board layout.
Can the MCF54452VP266 boot directly from SPI flash memory?
Yes, the MCF54452VP266 supports booting directly from SPI-compatible flash devices via its Serial Boot Facility (SBF). Boot mode is configured using BOOTMOD[1:0] pins, and the SBF automatically initializes the SPI interface, reads the boot image, and transfers execution to internal SRAM or external memory. This eliminates need for external boot ROM and simplifies firmware update workflows in field-deployed equipment.
How many independent Ethernet MACs does the MCF54452VP266 integrate?
The MCF54452VP266 integrates two independent 10/100 Fast Ethernet MACs (FEC0 and FEC1), each with full RMII/MII support, dedicated DMA channels, and hardware timestamping registers. Both MACs operate concurrently without shared resources, enabling true dual-port routing, bridging, or LAN/WAN segregation in industrial routers and firewalls - a key differentiator versus single-MAC ColdFire variants.
