NXP Semiconductors MCF5282CVM80

Overview

MCF5282CVM80 from NXP (formerly Freescale) is a 32-bit ColdFire V2 microcontroller featuring an 80 MHz core clock, 256 KB on-chip Flash memory, 32 KB SRAM, integrated Fast Ethernet Controller (FEC), FlexCAN interface, and hardware EMAC unit - deployed in industrial networking gateways requiring deterministic real-time control and wired connectivity.

For engineers reviewing the MCF5282CVM80 datasheet, MCF5282CVM80 pinout, MCF5282CVM80 application, or MCF5282CVM80 equivalent, key selection criteria include FEC PHY interface timing compliance, QADC resolution and sampling rate, FlexCAN message buffer depth, ColdFire V2 ISA_A+ instruction set support, and 208-pin LQFP package thermal performance under continuous Ethernet + CAN operation.

Technical Context

The MCF5282CVM80 implements the ColdFire Version 2 microarchitecture with a 5-stage pipeline, 4 KB unified instruction/data cache, and enhanced multiply-accumulate (EMAC) unit supporting single-cycle 32×32→64-bit operations. It executes the ISA_A+ instruction set with full backward compatibility to earlier ColdFire cores.

Its system-level integration includes a programmable PLL for clock generation, dual interrupt controllers (INTC0/INTC1), SDRAM controller supporting up to 128 MB, and peripheral modules mapped into a flat 32-bit address space - all managed via the System Control Module (SCM) and Chip Configuration Module (CCM).

FAQ

What is the maximum operating frequency of the MCF5282CVM80?

The MCF5282CVM80 operates at a maximum core frequency of 80 MHz, achieved via its integrated Phase-Locked Loop (PLL) using an external 4–50 MHz crystal or oscillator input. This frequency is fully supported across the –40°C to +85°C industrial temperature range and enables real-time execution of Ethernet MAC-layer tasks and CAN protocol stacks without external acceleration. The MCF5282CVM80's timing specifications are validated per Freescale MCF5282UM Rev. 3 Section 2.3.5.

Does the MCF5282CVM80 include an integrated Ethernet PHY?

No, the MCF5282CVM80 integrates only the Fast Ethernet Controller (FEC) - a Media Access Control (MAC) layer IP block - and requires an external PHY chip (e.g., DP83848 or LAN8720) for physical layer signaling. Its MII/RMII interface signals (ENET_TXD[3:0], ENET_RXD[3:0], ENET_TX_EN, ENET_RX_ER, etc.) are routed directly to the PHY, with precise trace-length matching mandated for 100 Mbps operation. This separation allows flexible PHY selection and ESD protection design.

How much on-chip Flash and SRAM does the MCF5282CVM80 provide?

The MCF5282CVM80 integrates 256 KB of on-chip Flash memory (ColdFire Flash Module) and 32 KB of static RAM. The Flash supports in-application programming (IAP), sector protection, and security lock features; the SRAM is zero-wait-state at full speed and used for stack, heap, and real-time data buffers. Both memories are directly accessible via the ColdFire V2 linear address space and require no external bus logic - confirmed in MCF5282UM Sections 5 and 6.

What CAN protocol versions does the FlexCAN module in the MCF5282CVM80 support?

The FlexCAN module in the MCF5282CVM80 is compliant with ISO 11898-1:2003 (CAN 2.0B), supporting both standard (11-bit) and extended (29-bit) identifier formats, error confinement, automatic retransmission, and bit rates up to 1 Mbps. It implements 64 message object buffers with hardware acceptance filtering and time-triggered communication capabilities - detailed in MCF5282UM Section 1.2.2 and Chapter 22.

Is the MCF5282CVM80 pin-compatible with other ColdFire microcontrollers like the MCF5281 or MCF5280?

No, the MCF5282CVM80 is not pin-compatible with the MCF5281 or MCF5280. While all three belong to the ColdFire V2 family and share architectural similarities, they differ in pin count (MCF5282CVM80 = 208-pin LQFP; MCF5281 = 144-pin LQFP; MCF5280 = 160-pin LQFP), peripheral enablement (e.g., only MCF5282 includes FEC), and signal assignment. Migration requires PCB redesign and firmware adaptation - verified against Freescale's MCF5282UM Rev. 3 mechanical drawings and signal descriptions.
