Overview
MCF5282CVF66J from NXP (formerly Freescale) is a 32-bit ColdFire V2 core microcontroller featuring a 66 MHz CPU clock, 256 KB on-chip Flash memory, 32 KB SRAM, integrated Fast Ethernet Controller (FEC), FlexCAN interface, and QADC module - designed for industrial networking and real-time control applications requiring deterministic I/O and protocol stack integration.
For engineers reviewing the MCF5282CVF66J datasheet, MCF5282CVF66J pinout, MCF5282CVF66J application, or MCF5282CVF66J equivalent, key selection criteria include its 66 MHz operation with PLL-based clock synthesis, 10/100 Mbps Ethernet MAC with RMII/MII support, dual CAN 2.0B controllers, and 12-bit 16-channel analog-to-digital conversion capability - all in a 256-pin LQFP package.
Technical Context
The MCF5282CVF66J implements the ColdFire V2 microarchitecture with a 5-stage pipeline, 4 KB instruction/data unified cache, and enhanced multiply-accumulate (EMAC) unit supporting fractional arithmetic. It integrates a Phase-Locked Loop (PLL) for scalable system clocks up to 66 MHz from a 4–50 MHz crystal or external oscillator.
Its peripheral set includes a full-featured Fast Ethernet Controller (FEC) with DMA support, two independent FlexCAN modules compliant with ISO 11898-1, and a queued analog-to-digital converter (QADC) with configurable sample sequencing and hardware-triggered conversions - enabling tightly synchronized sensor acquisition and networked control loops.

FAQ
What is the maximum operating frequency of the MCF5282CVF66J?
The MCF5282CVF66J operates at a maximum core clock frequency of 66 MHz, achieved via its integrated Phase-Locked Loop (PLL) that multiplies an external 4–50 MHz crystal or oscillator input. This frequency is fully supported across commercial temperature range (–40°C to +85°C) and enables real-time execution of Ethernet and CAN protocol stacks without external acceleration.
Does the MCF5282CVF66J include on-chip Flash and SRAM?
Yes, the MCF5282CVF66J integrates 256 KB of on-chip Flash memory for program storage and 32 KB of SRAM for data and stack operations. The Flash supports in-system programming and sector protection, while the SRAM retains full functionality during low-power modes such as Wait and Doze - critical for fast wake-up response in industrial control applications.
What Ethernet interface options does the MCF5282CVF66J support?
The MCF5282CVF66J features a hardware Fast Ethernet Controller (FEC) supporting both MII and RMII physical layer interfaces. It includes dedicated DMA channels, VLAN tag handling, and IEEE 1588 timestamping registers - enabling implementation of time-sensitive networking (TSN) capable devices and industrial Ethernet protocols like EtherNet/IP without external PHY arbitration logic.
How many CAN interfaces does the MCF5282CVF66J provide?
The MCF5282CVF66J integrates two independent FlexCAN modules compliant with CAN 2.0A/B standards. Each module supports up to 64 message objects, programmable bit timing, and hardware acceptance filtering - allowing simultaneous operation on separate CAN buses, such as one for powertrain diagnostics and another for body electronics communication in automotive applications.
Is the MCF5282CVF66J pin-compatible with other ColdFire devices?
No, the MCF5282CVF66J is not pin-compatible with earlier ColdFire variants like the MCF5272 or MCF5206. Its 256-pin LQFP footprint and signal assignment are specific to the MCF528x family. Migration from other ColdFire generations requires PCB redesign and firmware adaptation due to differences in peripheral mapping, clock architecture, and memory layout.
