NXP Semiconductors MCF54450CVM180

Overview

MCF54450CVM180 from NXP Semiconductors is a ColdFire® Version 4 microprocessor with MMU and EMAC, operating at up to 180 MHz core clock, delivering up to 275 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 MCF54450CVM180 datasheet, MCF54450CVM180 pinout, MCF54450CVM180 application, or MCF54450CVM180 equivalent, key selection considerations include its 256-pin MAPBGA package, 180 MHz performance ceiling, DDR SDRAM controller support, USB 2.0 OTG with ULPI, and FlexBus external interface for legacy peripheral expansion.

Technical Context

The MCF54450CVM180 implements a ColdFire V4 core with hardware memory management unit (MMU) and enhanced multiply-accumulate (EMAC) unit, enabling real-time deterministic execution in embedded Linux or VxWorks environments. Its crossbar switch (XBS) architecture allows concurrent access to peripherals and RAM by multiple bus masters including CPU, DMA, and PCI.

It includes a 16-channel DMA controller, 4 periodic interrupt timers (PIT), 4 32-bit timers with DMA support, and a synchronous serial interface (SSI) for audio or codec interfacing. The device lacks PCI and ATA controllers-confirmed by family comparison table-and does not integrate cryptography acceleration (CAU) or ATA controller, distinguishing it from higher-tier MCF5445x variants.

FAQ

What is the maximum operating frequency of the MCF54450CVM180?

The MCF54450CVM180 operates at a maximum core clock frequency of 180 MHz, delivering up to 275 Dhrystone 2.1 MIPS. This speed grade is validated across the full industrial temperature range (–40°C to +85°C) and corresponds to the "C" suffix in the part number, indicating extended temperature qualification. The peripheral bus runs at half-core speed (90 MHz), and the external bus clock is derived at one-quarter core speed (45 MHz).

Does the MCF54450CVM180 include a PCI controller?

No, the MCF54450CVM180 does not include a PCI controller. According to the official MCF5445x Family Comparison table, PCI controller support begins with the MCF54452 variant and is absent in MCF54450 and MCF54451. The MCF54450CVM180 pinout omits all PCI_AD, PCI_CBE, and PCI_CTRL signals, confirming this exclusion. Designers requiring PCI must select MCF54452CVP200 or higher.

What package type and dimensions does the MCF54450CVM180 use?

The MCF54450CVM180 uses a 256-ball MAPBGA package measuring 17 mm × 17 mm with 1.0 mm ball pitch. It is lead-free and RoHS-compliant, classified as moisture sensitivity level 3 (MSL-3) per J-STD-020. This package is shared with the MCF54451CVM180 and is distinct from the 360-ball TEPBGA used by higher-performance variants like MCF54452CVP200.

Can the MCF54450CVM180 boot from NAND flash?

No, the MCF54450CVM180 does not support direct boot from NAND flash. Per the datasheet, it supports booting only from SPI-compatible flash, EEPROM, and FRAM devices via its serial boot facility (SBF). NAND flash requires additional controller logic and ECC management not integrated into the MCF54450CVM180's boot ROM, making external boot loader or companion controller necessary for NAND-based designs.

What is the function of the XBS (Crossbar Switch) in the MCF54450CVM180?

The Crossbar Switch (XBS) in the MCF54450CVM180 enables concurrent, non-blocking access to on-chip SRAM and peripherals by multiple bus masters-including the ColdFire core, DMA controller, and FlexBus interface. Unlike traditional shared bus architectures, XBS eliminates arbitration delays and contention bottlenecks, allowing simultaneous CPU instruction fetch, DMA transfers, and peripheral register access-critical for deterministic real-time performance in industrial control applications using the MCF54450CVM180.
