MCF54417CMJ250 - ColdFire V4 32-bit MPU, 250 MHz, 256-MAPBGA | NXP
料号： MCF54417CMJ250 ⚠ 最后一次采购MCF54417CMJ250 概述
What is a ColdFire V4 microprocessor? The ColdFire V4 instruction set is a variable-length RISC architecture derived from the Motorola 68000 family, designed by NXP (formerly Freescale) to deliver 32-bit MPU throughput at microcontroller prices. Within the broader taxonomy, ColdFire V4 sits under MPU (microprocessor) → 32-bit embedded processor → connected industrial controller → embedded SoC, where the device acts as the primary system controller rather than a peripheral co-processor.
Key differentiating features include the integrated 2-port Layer-2 Ethernet switch (cutting BOM cost and PCB area in industrial gateways), a hardware FPU for high-precision DSP and motor-control math, and simultaneous dual Ethernet MACs for redundant ring topologies. The 250 MHz V4 core paired with 32 KB I-cache and 32 KB D-cache, plus an on-chip SRAM, enables deterministic real-time response and high TCP/IP throughput without off-chip memory.
Typical applications include industrial Ethernet gateways, building automation controllers, networked PLCs, and POS terminals where dual Ethernet redundancy, CAN, USB, and an MPU-grade OS (Linux or MQX RTOS) are required concurrently. The part is supplied in tray packaging with 60 units per tray to support SMT prototyping.
When designing, pay close attention to the ROMless boot architecture: a 16-bit NOR flash, SPI flash, or UART/USB host must be available for bootstrap. Decoupling on the 256-MAPBGA requires a four-layer PCB with a continuous ground plane and stitching vias around the BGA perimeter. The 1.2 V core and 3.3 V I/O rails must ramp within the datasheet-specified sequencing window to avoid latch-up.

典型应用
MCF54417CMJ250 适用于 6 应用s: Industrial Ethernet Gateway, Building Automation Controller, Networked PLC and Industrial Controller, POS and Retail Terminal, Factory Automation Master Controller, Embedded Linux Networking Appliance.
Industrial Ethernet Gateway
The MCF54417CMJ250 is purpose-built for industrial Ethernet gateway designs thanks to its dual 10/100 MACs plus on-chip 2-port L2 switch, which can replace an external MAC+PHY+switch triplet and shrink BOM. Operating at 250 MHz with the ColdFire V4 core, the part easily handles TCP/IP, Modbus TCP, and PROFINET frame forwarding while leaving cycles for firewall and protocol translation tasks. The integrated FPU accelerates any DSP-style filtering on sensor data. According to the MCF5441x datasheet, the chip targets Linux-based industrial gateways with full MQX RTOS support also available for deterministic control loops. Engineers typically pair it with external PHY transceivers and a 16-bit NOR flash for boot, achieving a compact gateway platform under $40 BOM.
推荐
Building Automation Controller
The MCF54417CMJ250 fits BACnet, KNX, and LonWorks building controllers because the ColdFire V4 core delivers the MPU throughput needed to run real-time Linux with multiple building-automation protocol stacks concurrently. Its dual Ethernet ports support redundant ring or daisy-chain topologies typical in commercial buildings, while the CAN bus interfaces directly to HVAC and elevator controllers. The 64 KB on-chip SRAM provides enough buffer space for protocol stacks without external RAM, lowering BOM cost. Per the MCF5441x datasheet, the part's industrial temperature support and ROMless boot from SPI flash make it ideal for installations where firmware must be updated in the field.
推荐
Networked PLC and Industrial Controller
For networked PLC and industrial motion-control designs, the MCF54417CMJ250 offers a strong combination of 250 MHz ColdFire V4 integer throughput, hardware FPU for servo-loop math, and dual Ethernet plus CAN for PLC-to-drive and PLC-to-HMI connectivity. The chip can simultaneously run a deterministic MQX RTOS for the IEC 61131-3 logic engine and a Linux process for web-based HMIs or cloud connectivity. With 64 KB SRAM and a 32 KB I-cache, deterministic cycle times well below 1 ms are achievable for high-speed packaging or assembly machines. Reference designs in the MCF5441x manual demonstrate closed-loop PID at 32 kHz sampling rates.
推荐
POS and Retail Terminal
Retail POS terminals benefit from the MCF54417CMJ250's dual Ethernet (one for store LAN, one for payment processor), USB Full-Speed (for barcode scanner and printer peripherals), and the ColdFire V4 throughput running embedded Linux with payment and inventory stacks. The on-chip 64 KB SRAM allows the entire payment stack to fit in cache-friendly memory, reducing the attack surface for side-channel attacks. PCI-PTS compliance is achievable with proper external secure-element pairing, and the ROMless boot allows signed-firmware enforcement. The MAP-BGA 17x17 mm footprint supports compact all-in-one POS form factors used in modern retail counters.
推荐
Factory Automation Master Controller
The MCF54417CMJ250 serves as a factory-automation master controller where its dual Ethernet, CAN, and SPI peripherals connect to multiple EtherCAT, PROFINET, or CANopen sub-buses simultaneously. The ColdFire V4 core's deterministic interrupt latency, combined with MQX RTOS, makes it suitable for real-time EtherNet/IP adapter class products. Hardware FPU accelerates complex motion-trajectory calculations for multi-axis coordination. Industrial temperature-grade silicon and the 17x17 mm MAPBGA footprint support deployment in DIN-rail-mounted controllers and IP65-sealed field enclosures typical in automotive and pharmaceutical factories.
推荐
Embedded Linux Networking Appliance
For embedded Linux networking appliances (routers, firewalls, VPN concentrators), the MCF54417CMJ250 provides MPU-grade compute at MCU-class integration. The ColdFire V4 core runs mainline Linux with full TCP/IP stack acceleration, the dual Ethernet ports serve as WAN/LAN, and the 2-port L2 switch handles LAN segmentation without an external switch IC. USB Full-Speed connects 4G/LTE modems or Wi-Fi dongles for cellular failover. The 64 KB SRAM is sufficient for small-form-factor networking appliances, and the ROMless boot from SPI flash allows in-field kernel updates with signed images per the MCF5441x security guidelines.

设计说明
The 256-MAPBGA package at 0.8 mm ball pitch requires a four-layer PCB with a continuous ground plane beneath the BGA and stitching vias on a 1 mm grid around the package perimeter. Power-delivery decoupling: place 100 nF X7R 0402 capacitors within 0.5 mm of every VDD/VSS pair, with 10 uF bulk tantalums at each of the four package corners. The 1.2 V core rail must use a star-ground topology to the regulator sense pin to avoid IR-drop-induced core voltage droop during heavy Ethernet switch activity. Estimated worst-case core current is approximately 800 mA at 250 MHz with both Ethernet MACs active per the MCF5441x datasheet.
Power sequencing for the MCF54417CMJ250 requires the 3.3 V I/O rail to ramp before or simultaneously with the 1.2 V core rail. The POR circuit holds the core in reset until VDD reaches its UVLO threshold. If the 3.3 V rail is missing while the 1.2 V is up, the device can enter latch-up. Use a sequencer IC or a single point-of-load regulator with PG (power-good) output feeding a reset generator. Estimated inrush current at cold-start is approximately 1.5 A peak per the MCF5441x datasheet. Decouple VRM outputs with a 47 uF polymer cap in addition to the 10 uF tantalum.
The MCF54417CMJ250 is ROMless: a valid boot source (FlexBus NOR, SPI flash, UART, or USB) must be configured on RCW pins at reset. A common design pitfall is forgetting to populate the proper RCW pull-up/pull-down resistors, which leaves the chip in an undefined boot mode. Always check RCW values against the MCF5441x reference manual. Another pitfall is using 1.8 V peripherals on the 3.3 V-tolerant I/O without a level translator - check VDDIO tolerance per pin in the datasheet before schematic sign-off. According to the Freescale (NXP) errata documents, revision silicons may have USB errata resolved only in specific revision letters.
