NXP Semiconductors MCF5484CVR200

Overview

MCF5484CVR200 from Freescale Semiconductor is a ColdFire V4e-core microprocessor designed for high-performance embedded networking and industrial control applications. It operates at up to 200 MHz core frequency (308 MIPS @ 200 MHz), integrates a 32-Kbyte instruction cache, 32-Kbyte data cache, MMU, FPU compliant with IEEE-754 double-precision, and supports DDR/SDR SDRAM up to 1 GB via four chip selects.

For engineers reviewing the MCF5484CVR200 datasheet, MCF5484CVR200 pinout, MCF5484CVR200 application, or MCF5484CVR200 equivalent, this part delivers deterministic real-time processing with dual FlexCAN 2.0B controllers, two 10/100 Mbps FECs, USB 2.0 device controller, and hardware cryptography acceleration - critical for secure industrial gateways and protocol-converged edge devices.

Technical Context

The MCF5484CVR200 implements a limited-superscalar ColdFire V4e core with Harvard architecture, separate 32-entry fully-associative instruction and data translation lookahead buffers, and integrated memory management unit enabling full Linux OS support. Its internal XLB bus arbiter coordinates concurrent access between CPU, DMA, FECs, and crypto accelerator.

It features a 32-bit DDR SDRAM controller (66–133 MHz), PCI 2.2 interface (33–66 MHz), FlexBus for glueless flash/SRAM/peripheral interfacing (33–66 MHz), and a communications I/O subsystem including dual FECs with 2-Kbyte FIFOs each, four PSCs with 512-byte FIFOs, I²C, DSPI, and two FlexCAN controllers with 16 message buffers each.

FAQ

What is the maximum DDR SDRAM clock frequency supported by the MCF5484CVR200?

The MCF5484CVR200 supports DDR SDRAM operation up to 133 MHz, as specified in the MCF5485EC Rev. 4 datasheet Section 9.2. This enables peak theoretical bandwidth of 1.06 GB/s across a 64-bit interface. The controller supports both DDR and SDR modes but not simultaneously, and includes built-in initialization and refresh logic. MCF5484CVR200 requires SSTL-2 Class I or II drive strength configuration for reliable DDR signaling.

Does the MCF5484CVR200 include a memory management unit (MMU)?

Yes, the MCF5484CVR200 integrates a full-featured MMU with separate 32-entry fully-associative instruction and data translation lookahead buffers. This enables virtual memory support required for protected operating systems such as Linux, VxWorks, or QNX. The MMU is part of the ColdFire V4e core architecture and is confirmed in the MCF5485EC Rev. 4 datasheet Feature List and Block Diagram. MCF5484CVR200 leverages this for process isolation and dynamic memory allocation in multi-tasking environments.

Can the MCF5484CVR200 operate without external SDRAM?

Yes, the MCF5484CVR200 can execute from internal resources: it contains 32-Kbyte system SRAM and supports booting from external NOR flash or ROM via its FlexBus interface. While DDR SDRAM is optional, the device requires at least one memory source - either internal SRAM (for minimal code execution) or external storage (for full OS or application loading). MCF5484CVR200's FlexBus enables glueless boot from common flash devices, and its SIU manages arbitration between internal masters accessing the 32-Kbyte SRAM.

What USB 2.0 functionality does the MCF5484CVR200 provide?

The MCF5484CVR200 integrates a USB 2.0 device controller compliant with USB Specification Revision 2.0, supporting control, interrupt, bulk, and isochronous transfers. It includes one control endpoint and six programmable endpoints, 4-Kbyte shared endpoint FIFO RAM, and 1-Kbyte descriptor RAM. An integrated physical layer (PHY) eliminates external transceivers, but requires precise 90Ω differential routing for D+/D− and an external 9.1kΩ USBRBIAS resistor. MCF5484CVR200 does not support USB host mode.

Is the MCF5484CVR200 pin-compatible with other MCF548x variants?

Yes, all MCF548x family members - including MCF5480, MCF5481, MCF5482, MCF5483, MCF5484, and MCF5485 - share identical TEPBGA–388 packaging and pinout per the MCF5485EC Rev. 4 datasheet. Functional differences (e.g., DDR vs. SDR only, number of FECs, crypto presence) are implemented internally and do not affect ball mapping. MCF5484CVR200 is therefore hardware-compatible with other MCF548x variants at the PCB level, enabling scalable design reuse across performance tiers.
