NXP Semiconductors MCF5484CZP200

Overview

MCF5484CZP200 from NXP Semiconductors (formerly Freescale) is a ColdFire V4e-based 32-bit microprocessor with integrated MMU, FPU, and dual Fast Ethernet controllers. It operates at up to 200 MHz core frequency (308 MIPS), supports DDR/SDR SDRAM up to 1 GB, and features PCI 2.2, FlexBus, USB 2.0 Device, two FlexCAN 2.0B controllers, and optional cryptography acceleration. It targets industrial networking gateways requiring deterministic real-time I/O and secure data handling.

For engineers reviewing the MCF5484CZP200 datasheet, MCF5484CZP200 pinout, MCF5484CZP200 application, or MCF5484CZP200 equivalent, key selection criteria include DDR SDRAM controller timing compliance, PCI bus master arbitration capability, ColdFire V4e core instruction cache coherency, and FlexCAN message buffer allocation - all verified for the TEPBGA-388 package at 200 MHz operation.

Technical Context

The MCF5484CZP200 implements a limited superscalar ColdFire V4e core with Harvard architecture, 32-Kbyte instruction and 32-Kbyte data caches, and a full Memory Management Unit (MMU) supporting virtual memory mapping. Its internal XLB bus arbiter enables concurrent access by multiple masters including the CPU, DMA, FECs, and USB controller.

It integrates a 32-bit DDR SDRAM controller operating at 66–133 MHz with built-in initialization and refresh logic, a PCI 2.2 interface supporting 33–66 MHz with five external master slots, and a flexible multi-function FlexBus running at 33–66 MHz with six chip selects and glueless boot ROM/SRAM interfacing.

Compared with MCF5485CZP200, the MCF5484CZP200 reduces pin count and eliminates redundant USB functionality while retaining full DDR, PCI, and dual-FEC capability - making it optimal for cost-sensitive, device-only embedded gateways. Against MPC8313EVRAGDB, it trades raw MHz for deterministic ColdFire V4e interrupt latency and mature MQX/Linux BSP support.

FAQ

What is the maximum DDR SDRAM clock frequency supported by the MCF5484CZP200?

The MCF5484CZP200 DDR SDRAM controller supports operation up to 133 MHz, enabling peak theoretical bandwidth of 1.06 GB/s with a 64-bit bus. This is confirmed in Section 9.2 of the MCF5485EC datasheet (Rev. 4), which applies identically to the MCF5484CZP200 as part of the MCF548x family. The controller supports both single-data-rate and double-data-rate modes but not simultaneously.

Does the MCF5484CZP200 include a hardware floating-point unit?

Yes, the MCF5484CZP200 integrates a full IEEE-754-compliant double-precision floating-point unit (FPU) with eight dedicated registers. This FPU is part of the ColdFire V4e core and is enabled by default upon reset. It supports addition, multiplication, division, square root, and transcendental operations - critical for motion control and signal processing in the MCF5484CZP200's target applications.

What are the power supply sequencing requirements for the MCF5484CZP200?

The MCF5484CZP200 requires strict voltage sequencing: IVDD/PLLVDD and EVDD/SDVDD must track up to 0.9 V, then separate, with IVDD never exceeding EVDD or SDVDD by more than 0.4 V. Rise times must be slower than 1 µs to avoid ESD diode conduction. These constraints are documented in Section 4.2 of the MCF5485EC datasheet and apply directly to the MCF5484CZP200.

Is the MCF5484CZP200 pin-compatible with other MCF548x variants?

Yes, the MCF5484CZP200 is fully pin-compatible with the MCF5480–MCF5485 family in the TEPBGA-388 package, including identical ball map, power pin assignment, and I/O function layout. Differences are internal (e.g., USB port count, CommBus presence) and do not affect PCB layout - confirmed in the "MCF548x ColdFire Microprocessor" overview on page 2 of the MCF5485EC datasheet.

What debugging interfaces does the MCF5484CZP200 support?

The MCF5484CZP200 supports ColdFire Background Debug Mode (BDM) via the PSTCLK and PSTDDATA[7:0] pins, and IEEE 1149.1 JTAG boundary scan through dedicated TCK, TMS, TDI, TDO, and TRST pins. Both interfaces are electrically and logically identical across the MCF548x family and validated for use with standard Freescale/NXP debug tools like CodeWarrior and PE Micro.
