NXP Semiconductors MCF5471VR200

Overview

MCF5471VR200 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 (310 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 MCF5471VR200 datasheet, MCF5471VR200 pinout, MCF5471VR200 application, or MCF5471VR200 equivalent, key selection considerations include its 388-pin TEPBGA package, 1.5V core / 2.5V DDR / 3.3V I/O voltage domains, dual 10/100 Mbps FECs with dedicated 2-Kbyte FIFOs per channel, USB 2.0 device controller with integrated PHY, and support for PCI 2.2 at 33–66 MHz.

Technical Context

The MCF5471VR200 implements a limited superscalar ColdFire V4e core with Harvard architecture, separate 32-entry fully associative instruction and data translation lookahead buffers, and an integrated floating-point unit. Its internal XLB bus arbiter enables high-performance split transactions between the core, DMA, and peripherals.

It features a flexible multi-function FlexBus interface (33–66 MHz) with six chip selects for glueless boot flash/SRAM/peripheral interfacing, a 32-bit DDR SDRAM controller supporting 66–133 MHz operation, and a version 2.2 PCI interface supporting up to five external masters with configurable bus-to-XLB divider ratios (1:1, 1:2, 1:4).

FAQ

What is the maximum operating junction temperature for the MCF5471VR200?

The MCF5471VR200 has a maximum operating junction temperature of 105°C, as specified in Table 2 of the MCF5475EC datasheet Rev. 4. This limit must be maintained under all operating conditions, including worst-case ambient temperature and power dissipation. Thermal design should use the θJMA value of 19°C/W (388-pin TEPBGA, four-layer board) to ensure reliable long-term operation of the MCF5471VR200.

Does the MCF5471VR200 support both DDR and SDR SDRAM simultaneously?

No, the MCF5471VR200 SDRAM controller supports either DDR or SDR SDRAM operation-but not both concurrently. The mode is selected at reset via configuration pins and cannot be changed dynamically. DDR mode enables higher bandwidth (up to 133 MHz) and is required for applications needing >800 MB/s memory throughput; SDR mode offers simpler layout and lower power for cost-sensitive designs. This constraint applies strictly to the MCF5471VR200.

What voltage domains does the MCF5471VR200 require?

The MCF5471VR200 requires three distinct voltage domains: 1.5V ±0.07V for internal logic (IVDD), 2.5V ±0.2V for DDR SDRAM I/O (SDVDD), and 3.3V ±0.3V for PCI, FlexBus, and all other I/O (EVDD). The USB subsystem further requires five dedicated supplies: USBVDD, USB_PHYVDD, USB_PLLVDD, USB_OSCVDD, and USB_OSCAVDD-each with specific filtering per Figure 6 and Table 5 in the MCF5475EC datasheet. All domains must follow strict sequencing rules to avoid ESD diode conduction.

Is the USB interface on the MCF5471VR200 a full-speed or high-speed device controller?

The MCF5471VR200 integrates a USB 2.0 device controller with an integrated physical layer (PHY), supporting both full-speed (12 Mbps) and high-speed (480 Mbps) operation. The USB_D+ and USB_D− pins are routed as a 90 Ω differential pair per Section 4.3.1 of the MCF5475EC datasheet, and the internal PHY eliminates need for external transceivers. High-speed mode requires proper USBVBUS detection using the recommended voltage divider (Figure 4 or 5) to ensure reliable enumeration of the MCF5471VR200.

Can the MCF5471VR200 operate without external SDRAM?

Yes, the MCF5471VR200 can execute code from internal resources: 32-Kbyte instruction cache, 32-Kbyte data cache, and 32-Kbyte on-chip system SRAM. Booting from internal SRAM or FlexBus-connected flash (e.g., via FBCS0) is supported for minimal configurations. However, sustained application execution typically requires external SDRAM due to size limitations of on-chip memory. The MCF5471VR200 does not include embedded flash or ROM, so external non-volatile storage is mandatory for production firmware storage.
