NXP Semiconductors MCF5475ZP200

Overview

MCF5475ZP200 from Freescale Semiconductor is a ColdFire V4e core microprocessor designed for high-performance embedded networking and industrial control applications. It operates at up to 266 MHz core frequency (410 MIPS), 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 MCF5475ZP200 datasheet, MCF5475ZP200 pinout, MCF5475ZP200 application, or MCF5475ZP200 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 optional cryptography accelerator supporting AES, DES/3DES, SHA-256, and RNG.

Technical Context

The MCF5475ZP200 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 manages concurrent access from multiple masters including the CPU, DMA, FECs, and USB subsystem.

It features a flexible multi-function FlexBus interface operating at 33–66 MHz with six chip selects, a PCI 2.2 controller supporting 33–66 MHz with five external master slots, and a communications I/O subsystem comprising two FECs, one USB 2.0 device controller, four PSCs, I²C, and DSPI-all backed by an intelligent 16-channel DMA controller.

Key Specifications

Pinout & Package

FAQ

What is the maximum DDR SDRAM clock frequency supported by the MCF5475ZP200?

The MCF5475ZP200 supports DDR SDRAM operation up to 133 MHz, corresponding to a 266 MT/s data rate. This is achieved through its integrated DDR SDRAM controller with built-in initialization, refresh, and programmable drive strength for SSTL_2/SSTL_3 I/O standards. The controller supports up to four chip selects and addresses up to 1 GB of external memory. All timing parameters-including tRCD, tRP, and tRAS-are configurable via memory controller registers per JEDEC DDR specifications.

Does the MCF5475ZP200 include an integrated USB physical layer?

Yes, the MCF5475ZP200 includes a fully integrated USB 2.0 physical layer (PHY) supporting high-speed (480 Mbps) and full-speed (12 Mbps) operation. It provides dedicated USBD+ and USBD− pins with on-die termination and biasing, eliminating the need for an external transceiver. The USB controller supports one control endpoint and six programmable endpoints (interrupt, bulk, or isochronous), backed by 4 KB of shared endpoint FIFO RAM and 1 KB of descriptor RAM.

What voltage domains does the MCF5475ZP200 require, and how must they be sequenced during power-up?

The MCF5475ZP200 requires three distinct voltage domains: 1.5 V for core logic (IVDD/PLL VDD), 2.5 V for DDR SDRAM I/O (SD VDD), and 3.3 V for PCI, FlexBus, and general-purpose I/O (EVDD). Per Freescale MCF5475EC Rev. 4 Section 4.2.1, IVDD/PLL VDD and EVDD/SD VDD must track up to 0.9 V, then separate-IVDD must not exceed EVDD or SD VDD by more than 0.4 V at any time. All supplies must ramp with ≤1 µs rise time to avoid ESD clamp conduction.

Can the MCF5475ZP200 execute Linux, and what memory management features enable this?

Yes, the MCF5475ZP200 supports full Linux kernel execution due to its integrated Memory Management Unit (MMU) with separate 32-entry fully-associative instruction and data translation lookahead buffers. The MMU enables virtual memory addressing, process isolation, and demand-paged memory management-essential for POSIX-compliant OS environments. Combined with 32-Kbyte instruction and data caches and 266 MHz core performance, it delivers sufficient throughput for real-time Linux distributions such as MontaVista or Wind River Linux.

What debugging interfaces are available on the MCF5475ZP200?

The MCF5475ZP200 provides two standardized debugging interfaces: a ColdFire Background Debug Mode (BDM) port with PSTCLK and PSTDDATA[7:0] signals for real-time emulation and flash programming, and a JTAG/IEEE 1149.1 test access port supporting boundary scan, device identification, and debug halt control. Both interfaces are accessible via the 388-ball TEPBGA package and are documented in Sections 14 and 23 of the MCF5475EC datasheet.
