NXP Semiconductors MCF54455CVR200

Overview

MCF54455CVR200 from NXP Semiconductors is a ColdFire® Version 4 microprocessor with MMU and EMAC, operating at 200 MHz core clock, delivering 370 Dhrystone 2.1 MIPS, featuring 32-KB on-chip SRAM, dual 10/100 Ethernet MACs, and a 32-bit PCI controller - deployed in industrial networking gateways requiring deterministic real-time processing and multi-protocol connectivity.

For engineers reviewing the MCF54455CVR200 datasheet, MCF54455CVR200 pinout, MCF54455CVR200 application, or MCF54455CVR200 equivalent, key selection criteria include DDR SDRAM controller timing compliance, PCI bus arbitration behavior, FEC RMII vs. MII interface configuration, and boot source flexibility (SPI flash/FRAM/EEPROM).

Technical Context

The MCF54455CVR200 implements a superscalar ColdFire V4 core with integrated MMU for full virtual memory support and an enhanced multiply-accumulate unit (EMAC) optimized for signal processing workloads. Its crossbar switch (XBS) enables concurrent access to peripherals and RAM by multiple bus masters including CPU, DMA, and PCI.

It integrates a 16-channel DMA controller supporting scatter-gather transfers, a 16-bit 133-MHz DDR/mobile-DDR/DDR2 SDRAM controller with programmable timing, and dual Fast Ethernet controllers compliant with IEEE 802.3u, each configurable for MII or RMII physical layer interfaces.

Key Specifications

Pinout & Package

FAQ

What is the operating temperature range for the MCF54455CVR200?

The MCF54455CVR200 is rated for –40°C to +85°C, qualifying it for deployment in harsh industrial environments such as factory automation cabinets, outdoor telecom enclosures, and transportation control systems where ambient temperatures exceed commercial-grade limits.

Does the MCF54455CVR200 support DDR2 memory?

Yes, the MCF54455CVR200 includes a 16-bit DDR2 SDRAM controller operating at 133 MHz, supporting JEDEC-standard DDR2-266/333 devices with programmable CAS latency, tRCD, and tRP timing parameters - verified in NXP reference design RD-MCF54455.

How does the MCF54455CVR200 handle boot configuration?

The MCF54455CVR200 uses BOOTMOD[1:0] pins to select boot source and port size, supporting serial boot from SPI-compatible flash, EEPROM, or FRAM devices. Boot mode is latched at reset and determines initial vector fetch location and bus width initialization sequence.

Can the MCF54455CVR200 operate in PCI target mode?

Yes, the MCF54455CVR200 supports both PCI master and target modes. In target mode, it responds to memory-mapped I/O reads/writes from a host PCI controller, with programmable BARs and interrupt assertion via PCI_INTA - confirmed in Section 5.9 of the MCF5445x datasheet Rev. 9.

Is the CAU in the MCF54455CVR200 FIPS 140-2 certified?

The CAU in the MCF54455CVR200 implements cryptographic algorithms per FIPS PUB 46-3 (DES), FIPS PUB 197 (AES), and FIPS PUB 180-2 (SHA-1), but NXP does not claim full FIPS 140-2 module certification for the MCF54455CVR200; validation requires system-level testing per NIST guidelines.
