MCF5282CVM80J 概要
A ColdFire V2 microcontroller is a member of the 32-bit microcontroller family based on the Freescale/NXP ColdFire instruction set architecture, a reduced instruction set computing (RISC) derivative of the Motorola 68000 family. Positioned within the broader taxonomy, ColdFire V2 -> 32-bit MCU -> microcontroller -> embedded processor -> semiconductor, this device class simplifies embedded Ethernet-networked designs by integrating networking peripherals with general-purpose I/O, DMA, and memory interfaces on a single die.
Key features include 150 general-purpose I/O lines, a ColdFire V2 core with up to 80 MHz operation, 512 KB on-chip flash program memory, 64 KB on-chip SRAM, an integrated 10/100 Mbps Ethernet MAC with Media Independent Interface (MII), two CAN 2.0B controllers, three UART/USART ports, a queued SPI module, and an I2C bus interface. Additional peripherals include DMA channels, PWM outputs, a low-voltage detect (LVD) module, a power-on reset (POR), and a watchdog timer.
The architecture uses a Harvard-style memory bus with a ColdFire V2 enhanced multiply-accumulate (EMAC) unit, achieving 80 Dhrystone 2.1 MIPS at 80 MHz while maintaining code density advantages over ARM7. The MAPBGA-256 package supports high-pin-count peripheral multiplexing across external bus interfaces, EBI/EMI, and SDRAM controller signals.
Typical applications include industrial Ethernet gateways, building automation controllers, point-of-sale terminals, networked sensor hubs, and CAN/Ethernet bridges. The integrated Ethernet MAC with MII allows direct connection to a PHY such as the KSZ8041, while the dual CAN controllers suit automotive and industrial Control Area Network backbones.
When designing with this device, ensure the MAPBGA-256 PCB land pattern uses 1.0 mm pitch balls with proper microvia or via-in-pad construction, since high-speed Ethernet signals require controlled impedance traces. The external bus interface supports glueless connection to SDRAM and flash; adding a 32 kHz external crystal is required for the real-time clock and timing reference.

主な用途
MCF5282CVM80J の用途: 6 件s: Industrial Ethernet Gateway, Building Automation Controller, Point-of-Sale (POS) Terminal, CAN/Ethernet Protocol Bridge, Networked Sensor Hub, Industrial Printer Controller.
Industrial Ethernet Gateway
The MCF5282CVM80J's integrated 10/100 Ethernet MAC with MII allows direct connection to a PHY such as the KSZ8041, eliminating an external MAC chip and reducing BOM cost. ColdFire V2 at 80 MHz provides deterministic interrupt latency required for industrial protocols like EtherNet/IP and PROFINET. The 150 GPIO and external bus interface support glueless connection to SDRAM and peripheral logic. Dual CAN 2.0B controllers enable bridging from Ethernet to industrial CAN networks. The 256-MAPBGA package accommodates high-pin-count industrial designs.
おすすめ
Building Automation Controller
Building automation systems require multiple serial interfaces for HVAC, lighting, and access control subsystems. The MCF5282CVM80J provides three UART/USART ports, SPI, and I2C, covering BACnet MS/TP (RS-485 via UART), DALI lighting (via SPI), and sensor I/O expansion (via I2C). The 80 MHz ColdFire V2 core handles BACnet/IP stack with headroom for application logic. Ethernet MAC enables web-based configuration and remote monitoring. The -40C to +85C industrial temperature range suits mechanical room and rooftop installations.
おすすめ
Point-of-Sale (POS) Terminal
POS terminals integrate Ethernet for payment processing, multiple serial ports for peripherals (barcode scanner, receipt printer, customer display), and secure keypad/magnetic-stripe reader interfaces. The MCF5282CVM80J's 512 KB flash stores TCP/IP stacks (lwIP or uIP) plus payment application code, while 64 KB SRAM buffers transaction data. The ColdFire V2 EMAC unit accelerates cryptographic primitives for payment security. External bus interface allows glueless connection to a graphic LCD controller and external SRAM for transaction logging.
おすすめ
CAN/Ethernet Protocol Bridge
The MCF5282CVM80J is purpose-built for industrial gateways translating between CAN bus field devices and Ethernet supervisory networks. Dual CAN 2.0B controllers handle multiple CAN channels at 1 Mbps each, while the 10/100 Ethernet MAC connects to factory networks. ColdFire V2's deterministic interrupt handling ensures CAN message deadlines are met under Ethernet load. DMA channels offload CAN/Ethernet packet movement, freeing the CPU for protocol translation logic. The 256-MAPBGA package supports high-pin-count designs with external bus peripherals.
おすすめ
Networked Sensor Hub
IoT sensor hubs aggregate data from multiple sensor interfaces and publish over Ethernet. The MCF5282CVM80J's I2C and SPI interfaces connect to temperature, humidity, and accelerometer sensors; the UART connects to wireless modules; and the Ethernet MAC publishes aggregated data via MQTT or HTTP. The 150 GPIO handles discrete sensors and actuator outputs. ColdFire V2 at 80 MHz runs a small RTOS (uClinux or FreeRTOS-ColdFire) for sensor fusion and network protocol stacks. The -40C to +85C range suits outdoor enclosure deployments.
おすすめ
Industrial Printer Controller
Industrial label and barcode printers require fast Ethernet for job submission and multiple serial interfaces for operator panels and scanners. The MCF5282CVM80J's 80 MHz ColdFire V2 core drives print engines via PWM and DMA, while Ethernet accepts print jobs at line speed. The 512 KB flash stores font tables and firmware; 64 KB SRAM buffers rasterized label images. The external bus interface supports additional SRAM for large label buffers, and the 256-MAPBGA package accommodates high-pin-count motor drive and sensor feedback signals.

設計ノート
The 256-MAPBGA package uses 1.0 mm ball pitch and requires via-in-pad or microvia PCB technology for reliable reflow soldering. Per NXP application note guidance, place a 0.1 uF decoupling capacitor within 5 mm of every power/ground ball pair to suppress switching noise on the ColdFire V2 core. The exposed die paddle should be soldered to a continuous ground plane to provide thermal dissipation; without this, junction temperature can exceed 100C at full 80 MHz operation.
Route the Ethernet MII signals (TXD[3:0], RXD[3:0], TX_EN, RX_DV, CRS, COL, MDC, MDIO) with controlled 50-ohm impedance traces and length matching within 25 mils to maintain signal integrity at 100 Mbps. The MII clock runs at 25 MHz at 100BASE-TX, with rise times below 5 ns - keep these traces short and away from switching power signals. Per the MCF5282 reference design, place the PHY within 50 mm of the MCU to minimize signal degradation and EMC emissions.
Estimated: at 80 MHz with all peripherals active, the ColdFire V2 core draws approximately 200 mA at 3.3V (estimated, not datasheet-confirmed). With theta_JA around 25 C/W for the 256-MAPBGA package (estimated), junction-to-ambient thermal resistance results in a 5 C temperature rise per 100 mA. For full industrial temperature operation, ensure the ground paddle is soldered to a 4-layer PCB with at least 1 square inch of ground copper pour.
Do not omit the external 32 kHz crystal for the real-time clock - the on-chip oscillator requires this reference for RTC and timing operations. Avoid using both CAN controllers simultaneously at maximum bus load (1 Mbps) without verifying interrupt priority - ColdFire V2 has limited interrupt nesting depth. Always program the flash wait states according to the System Clock chapter of the reference manual to avoid data corruption at 80 MHz.
