MCF5271CVM100 概要
What is a ColdFire V2 MPU? The ColdFire V2 architecture is a 32-bit RISC instruction set derived from the original m68k family, optimized for high code density and low power. The MCF5271 sits in the power-management and connectivity sub-hierarchy of embedded processors: it is neither a microcontroller with internal flash nor a full applications processor. Instead, it is an MPU that typically pairs with external SDRAM/NOR/NAND memory and runs a real-time operating system such as uClinux, MQX, or NetBSD. The V2 ColdFire core delivers up to 100 MIPS at 100 MHz (Dhrystone 2.1) while consuming far less power than ARM9-class parts of the same era, making it attractive for industrial controllers, point-of-sale terminals, and networked sensor gateways.
Key features include a 32-bit V2 ColdFire core with hardware multiply/accumulate, 64 KB unified SRAM, a 4-channel DMA controller, integrated 10/100 Ethernet MAC with MII/RMII PHY interface, dual CAN 2.0B modules, USB 1.1 device/host/OTG, three UARTs, two I2C buses, queued SPI, four 16-bit timers, and a 16-channel eTPU. The 196-LBGA package exposes 61 GPIO and the full external memory bus for SDRAM, NAND flash, and NOR flash expansion.
Designers select this part when Ethernet plus CAN plus USB must coexist on a single die without an external PHY controller (PHY required for Ethernet), and when the firmware team already has ColdFire expertise. The MCF5271 competes architecturally with ARM7TDMI and ARM9 parts but offers better deterministic interrupt latency and a richer peripheral set for industrial networking.
Typical applications include industrial Ethernet/CAN gateways, factory automation PLCs, building automation controllers, point-of-sale terminals, networked printers, and motor-control HMI panels. The wide peripheral integration reduces external component count and BOM cost on connected industrial designs.
When designing with the MCF5271, verify DDR or SDRAM timing parameters against your chosen memory data sheet. Place a 32.768 kHz crystal for the RTC and 25 MHz for the system PLL, and provide proper decoupling on every VDD/VSS pair. The boot mode pins must be pulled correctly for the desired fetch source (NOR flash, NAND flash, or serial boot).

主な用途
MCF5271CVM100 の用途: 7 件s: Industrial Ethernet Gateway, Building Automation Controller, Point-of-Sale Terminal, Networked Printer Controller, Motor Control HMI Panel, Connected Sensor Hub, Factory Automation PLC.
Industrial Ethernet Gateway
The MCF5271CVM100 integrates 10/100 Ethernet MAC with MII/RMII and dual CAN 2.0B, making it ideal for industrial gateway applications that bridge factory-floor CAN networks to Ethernet backbones. The 100 MHz ColdFire V2 core delivers enough headroom to run TCP/IP stacks alongside CANopen or DeviceNet protocols without external bus mastering. Engineers typically pair it with an external PHY and 32 MB SDRAM for protocol buffering. Power dissipation stays under 1 W at full load, simplifying thermal design in DIN-rail enclosures.
おすすめ
Building Automation Controller
Building automation systems require multiple serial buses, timers, and deterministic control loops. The MCF5271CVM100 provides three UARTs for BACnet, Modbus, and RS-485 trunks, plus four 16-bit timers and eTPU for HVAC and lighting control. The 64 KB on-chip SRAM is sufficient for a small BACnet stack, and the ROMless boot allows field firmware updates through the QSPI port. The 196-LBGA package fits standard 4-layer building automation controller PCBs.
おすすめ
Point-of-Sale Terminal
POS terminals need USB device/host support, Ethernet for payment processing, and UART for receipt printers. The MCF5271CVM100 integrates USB 1.1 host/device/OTG plus 10/100 Ethernet MAC, eliminating the need for external bridge chips. The ColdFire V2 core runs encrypted payment protocols at 100 MIPS, sufficient for EMV chip-card transactions. Dual CAN is unused in POS but available for future peripheral integration. The 196-LBGA keeps PCB area minimal in compact countertop terminals.
おすすめ
Networked Printer Controller
Networked printers require Ethernet for network connectivity, USB for direct print jobs, and timers for motor control. The MCF5271CVM100 integrates all three, plus eTPU for paper-feed and print-head stepper control. The 100 MHz core handles PCL or PostScript rasterization at moderate speeds, and the 64 KB SRAM buffers print jobs before DMA transfers them to the print engine. The 196-LBGA is industry-standard for embedded printer designs.
おすすめ
Motor Control HMI Panel
Industrial motor control HMI panels integrate CANopen for drive communication, USB for programming, and Ethernet for plant-wide monitoring. The MCF5271CVM100 dual CAN modules drive two independent motor drives simultaneously, while the 10/100 Ethernet streams telemetry to a SCADA system. The eTPU module generates precise PWM outputs for direct low-voltage motor control. The 196-LBGA package fits behind 5 to 10 inch HMI touchscreens with adequate thermal margin.
おすすめ
Connected Sensor Hub
Connected sensor hubs aggregate analog and digital sensors and forward readings over Ethernet or CAN. The MCF5271CVM100 64 KB SRAM buffers sensor bursts, the 4-channel DMA streams data without CPU intervention, and dual CAN provides redundancy in safety-critical deployments. The ColdFire V2 core runs at 100 MIPS, sufficient for local filtering and edge analytics. The 196-LBGA and 100 MHz clock give a balanced cost-to-performance ratio for industrial IoT edge devices.
おすすめ
Factory Automation PLC
Compact PLCs require deterministic real-time response, robust serial connectivity, and long-term reliability. The MCF5271CVM100 ColdFire V2 architecture provides deterministic interrupt latency within 10-20 cycles, three UARTs for sensor and actuator networks, and dual CAN for inter-PLC communication. The ROMless boot allows field-upgradable firmware over Ethernet, critical for 24/7 factory deployments. The 196-LBGA and industrial temperature support make it suitable for DIN-rail mounted PLCs.

設計ノート
The MCF5271CVM100 requires separate core and I/O supplies, typically 1.5V core and 3.3V I/O. According to NXP design guidelines, decouple every VDD/VSS pair with 100 nF ceramic capacitors placed within 5 mm of each ball, plus bulk 10 uF tantalum or polymer capacitors on each rail. Power sequencing must follow the datasheet-specified order to prevent latch-up.
The 196-LBGA package requires a 4-layer or 6-layer PCB with microvia-in-pad or fan-out via structures. Place external SDRAM traces within 25 mm of the address/data bus balls to maintain signal integrity. The 25 MHz system PLL reference clock trace must be routed with controlled impedance and shielded by ground planes on both sides.
Boot mode pins must be pulled to the correct levels at reset to select the desired fetch source (NOR flash, NAND flash, or serial boot). Incorrect boot configuration results in a silent CPU hang with no debug output. According to NXP errata documents, also verify that the RTC 32.768 kHz crystal oscillator load capacitors match the crystal specifications exactly.
