Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCF52259CAG80 | Same ColdFire V2 core but lower 80 MHz max frequency; 128 KB Flash, 32 KB RAM; no Ethernet MAC | Lacks integrated Ethernet - requires external MAC+PHY for LAN connectivity | Select when Ethernet is unnecessary and cost-sensitive BOM reduction is prioritized over network integration |
| Kinetis K60DN512ZVLQ10 | ARM Cortex-M4 core at 100 MHz; 512 KB Flash, 128 KB RAM; Ethernet MAC + USB + dual CAN; no FPU assist | Higher RAM and Flash capacity but lacks hardware FPU assist - floating-point workloads require software library overhead | Select when larger code footprint and ARM ecosystem tooling outweigh ColdFire-specific deterministic timing advantages |
Compared with MCF5249CVM140, MCF52259CAG80 trades Ethernet integration and clock speed for lower cost and power, while K60DN512ZVLQ10 offers greater memory headroom and ARM compatibility at the expense of ColdFire's tightly coupled interrupt latency and FPU assist efficiency.

FAQ
What is the maximum operating temperature range for the MCF5249CVM140?
The MCF5249CVM140 is rated for industrial temperature operation from –40 °C to +85 °C. This range is validated per JEDEC JESD22-A104 and applies to all specified electrical parameters including Flash programming endurance, SRAM retention, and Ethernet MAC timing margins. The MCF5249CVM140 maintains full functionality across this range without derating.
Does the MCF5249CVM140 support in-system programming via its integrated interfaces?
Yes, the MCF5249CVM140 supports in-system programming using its UART bootloader or via the background debug mode (BDM) interface. Firmware updates can be delivered over Ethernet using TFTP or over CAN using proprietary frame-based protocols. The MCF5249CVM140's Flash is organized in 2 KB sectors allowing partial reprogramming without erasing the entire memory.
Is an external PHY required for Ethernet operation on the MCF5249CVM140?
No, the MCF5249CVM140 integrates a full Ethernet MAC but not a physical layer transceiver. An external 10/100 Mbps PHY (e.g., DP83848 or LAN8720) is required for MII or RMII interface operation. The MCF5249CVM140 provides all necessary control signals, clock outputs, and MDIO management interface to drive standard IEEE 802.3-compliant PHYs.
How many CAN message buffers does each CAN controller support on the MCF5249CVM140?
Each of the two CAN 2.0B controllers on the MCF5249CVM140 supports 16 individually configurable message buffers, plus dedicated transmit and receive FIFOs. Buffer allocation is fully programmable via the CAN control registers, enabling flexible prioritization schemes for mixed criticality messages. This architecture is documented in Section 22.4.3 of the SCF5250 User's Manual.
What debug interface does the MCF5249CVM140 provide for development and testing?
The MCF5249CVM140 uses the 6-pin Background Debug Mode (BDM) interface compliant with Motorola/Freescale BDM specification v2.0. It supports full JTAG-like functionality including halt/resume, register read/write, memory access, and Flash programming. The MCF5249CVM140's BDM operates at up to 12 MHz and is compatible with P&E Micro and Segger J-Link debug probes via standard BDM adapters.
