NXP Semiconductors MCF5471ZP200

Overview

MCF5471ZP200 from NXP Semiconductors (formerly Freescale) is a ColdFire V4e-based 32-bit microprocessor with integrated DDR SDRAM controller, PCI 2.2 interface, dual 10/100 Mbps Ethernet controllers, USB 2.0 device controller, and optional cryptography accelerator. It operates at up to 266 MHz core frequency (410 MIPS), features 32 KB instruction and 32 KB data caches, MMU, FPU compliant with IEEE-754 double-precision, and targets high-performance embedded networking and industrial control applications.

For engineers reviewing the MCF5471ZP200 datasheet, MCF5471ZP200 pinout, MCF5471ZP200 application, or MCF5471ZP200 equivalent, key selection considerations include DDR/SDR memory support up to 1 GB, 388-pin TEPBGA package with 27 mm × 27 mm footprint, 1.5 V core / 2.5 V DDR / 3.3 V I/O voltage domains, and hardware-accelerated DES/3DES/AES/SHA-256 cryptographic operations.

Technical Context

The MCF5471ZP200 implements a limited superscalar ColdFire V4e core with Harvard architecture, separate 32-entry fully associative TLBs for instruction and data, and integrated floating-point unit. Its system-level interconnect includes an internal XLB arbiter supporting split transactions and parking modes, enabling concurrent access by multiple bus masters including the CPU, DMA, and peripheral controllers.

Peripheral subsystems are tightly coupled: the FlexBus provides glueless 33–66 MHz interfacing to boot ROM, SRAM, and peripherals via six chip-selects; the DDR SDRAM controller supports 66–133 MHz operation with built-in initialization and refresh; and the communications I/O subsystem integrates dual FECs with 2 KB FIFOs each, USB 2.0 device controller with PHY, four PSCs, I²C, and DSPI-all sharing a unified DMA engine.

FAQ

What is the maximum DDR SDRAM clock frequency supported by the MCF5471ZP200?

The MCF5471ZP200 DDR SDRAM controller supports operation up to 133 MHz, enabling peak theoretical bandwidth of 2.1 GB/s in double-data-rate mode. This is achieved with a 64-bit data bus and requires proper PCB layout adherence to DDR timing specifications in Table 13 of the MCF5475EC datasheet. The controller is not compatible with DDR2 or DDR3 standards.

Does the MCF5471ZP200 include a memory management unit (MMU)?

Yes, the MCF5471ZP200 includes a full-featured MMU supporting demand-paged virtual memory, essential for running Linux or other protected-mode operating systems. It implements a 32-bit address space with programmable page sizes and supports both supervisor and user modes - a key differentiator from earlier ColdFire generations without MMU.

Can the MCF5471ZP200 operate without external SDRAM?

Yes, the MCF5471ZP200 can execute code from internal resources: 32 KB system SRAM is available at reset and may be used for boot code or critical real-time tasks. However, full functionality - including Linux boot, large application images, and Ethernet packet buffering - requires external DDR or SDR SDRAM connected via the dedicated memory bus.

What voltage domains does the MCF5471ZP200 require?

The MCF5471ZP200 requires three distinct voltage domains: 1.5 V ± 0.07 V for IVDD/PLLVDD (core and PLL analog), 2.5 V ± 0.2 V for SDVDD (DDR I/O), and 3.3 V ± 0.3 V for EVDD (PCI, FlexBus, USB digital, and general I/O). Strict sequencing per Figure 3 in the datasheet is mandatory to prevent ESD diode conduction.

Is the cryptography accelerator in the MCF5471ZP200 enabled by default?

No, the cryptography accelerator module is optional and must be explicitly enabled via the CRYPTOEN bit in the SIU_SIUSCR register. When disabled, associated clock and power domains are gated. Its presence is confirmed in the MCF547x family datasheet, but functional validation requires firmware initialization and correct key scheduling per algorithm mode (AES, SHA, etc.) as defined in the reference manual.
