NXP Semiconductors MCF5282CVM80J

Overview

MCF5282CVM80J from NXP (formerly Freescale) is a 32-bit ColdFire V2 microcontroller featuring an 80 MHz core clock, 256 KB on-chip Flash, 32 KB SRAM, integrated Fast Ethernet Controller (FEC), FlexCAN, QADC, and QSPI-designed for industrial networking and real-time control applications such as programmable logic controllers and fieldbus gateways.

For engineers reviewing the MCF5282CVM80J datasheet, MCF5282CVM80J pinout, MCF5282CVM80J application, or MCF5282CVM80J equivalent, key selection criteria include its 80 MHz ColdFire V2 core with EMAC unit, dual CAN interface support, 10/100 Mbps Ethernet MAC+PHY integration, and 208-pin LQFP package with industrial temperature range (–40°C to +85°C).

Technical Context

The MCF5282CVM80J implements the ColdFire V2 microarchitecture with a 5-stage pipeline, 4 KB instruction/data cache, and enhanced multiply-accumulate (EMAC) unit supporting fractional arithmetic. It integrates a Phase-Locked Loop (PLL) for flexible clock generation up to 80 MHz from a 4–33 MHz crystal input.

Its system-level peripherals include a 32-bit SDRAM controller, external bus interface (EIM) with chip select logic, and comprehensive low-power management across Run, Wait, Doze, and Stop modes-enabling deterministic real-time response while meeting industrial power budgets.

FAQ

What is the maximum operating frequency of the MCF5282CVM80J?

The MCF5282CVM80J operates at a maximum core frequency of 80 MHz, achieved via its integrated Phase-Locked Loop (PLL) configured from a 4–33 MHz crystal input. This frequency is fully supported across the industrial temperature range (–40°C to +85°C) and enables real-time execution of protocol stacks including TCP/IP and CANopen without external acceleration. The MCF5282CVM80J datasheet specifies timing margins verified under worst-case voltage and temperature conditions.

Does the MCF5282CVM80J include an integrated Ethernet PHY?

No, the MCF5282CVM80J integrates only the Fast Ethernet Controller (FEC) MAC layer-not a physical layer (PHY). It supports both MII and RMII interfaces to external PHYs such as the DP83848 or LAN8720. The MCF5282CVM80J provides all necessary control, status, and data signals for seamless PHY interfacing, including auto-negotiation support and IEEE 802.3 compliance at 10/100 Mbps speeds.

How much on-chip Flash and SRAM does the MCF5282CVM80J provide?

The MCF5282CVM80J includes 256 KB of on-chip Flash memory (ColdFire Flash Module) and 32 KB of on-chip SRAM. The Flash supports in-application programming (IAP), sector protection, and security locking via dedicated CFM registers (CFMPROT, CFMSEC). The SRAM is contiguous, zero-wait-state at full speed, and retains data during low-power Stop mode - making it suitable for real-time data buffering and stack storage in the MCF5282CVM80J design.

What CAN protocol versions does the MCF5282CVM80J support?

The MCF5282CVM80J integrates two FlexCAN modules compliant with ISO 11898-1 (CAN 2.0B Active), supporting both standard (11-bit) and extended (29-bit) identifier frames. Each module includes 64 message buffers with configurable ID acceptance filtering, hardware timestamping, and bus-off recovery. The MCF5282CVM80J does not support CAN FD; for FD capability, migration to NXP's S32K series is required.

Is the MCF5282CVM80J pin-compatible with other ColdFire devices?

The MCF5282CVM80J shares the same 208-pin LQFP package and core peripheral mapping with the MCF5282CVM66J and MCF5282CVM40J, enabling frequency-scaling drop-in replacements. However, it is not pin-compatible with MCF5213 or MCF5223x families due to differing peripheral sets (e.g., missing FEC) and signal multiplexing. Always verify pin function tables in the MCF5282UM Rev. 3 manual before substituting the MCF5282CVM80J.
