Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCF52259CAG80 | Lower 80 MHz clock, 128 KB Flash, no USB OTG, adds SDHC controller and touch-sense interface | Better suited for cost-sensitive human-interface devices with card readers; lacks USB host capability required for MCF5249CVF140 use cases | Select only if USB OTG is unnecessary and SD card storage is mandatory |
| KINETIS K60DN512ZVLQ10 | ARM Cortex-M4 core, 100 MHz, 512 KB Flash, 128 KB RAM, USB OTG, Ethernet MAC, but no native CAN controllers | Requires external CAN transceivers and software CAN stack; higher RAM enables complex TCP/IP stacks but increases BOM and validation effort | Choose when migrating to ARM ecosystem and adding Ethernet+USB+TCP/IP is prioritized over CAN-native integration |
Compared with MCF5249CVF140, MCF52259CAG80 trades USB OTG and speed for lower cost and SDHC support, while K60DN512ZVLQ10 replaces integrated CAN with ARM flexibility and larger memory-requiring added hardware and software layers for CAN functionality.

FAQ
What is the maximum operating frequency of the MCF5249CVF140?
The MCF5249CVF140 operates at a maximum CPU frequency of 140 MHz, achieved using an external 20 MHz crystal with on-chip PLL multiplication (×7). This frequency is fully supported across the industrial temperature range (−40°C to +85°C) and validated in the SCF5250 User's Manual Chapter 22 hardware specifications.
Does the MCF5249CVF140 include an integrated USB PHY?
Yes, the MCF5249CVF140 integrates a full-speed USB 2.0 OTG PHY alongside its controller, eliminating the need for an external transceiver. The USB_DP and USB_DM pins connect directly to the USB connector with appropriate ESD protection and 90 Ω differential routing-confirmed in the MCF5249 Hardware Specifications document Rev. 0 (May 2009).
How much on-chip Flash and SRAM does the MCF5249CVF140 provide?
The MCF5249CVF140 provides 256 KB of on-chip Flash memory organized in 2 KB erasable sectors and 32 KB of zero-wait-state SRAM. Both memories are accessible in all operating modes, including low-power stop mode where SRAM retention is maintained at 25 µA typical current draw.
Which communication interfaces are integrated into the MCF5249CVF140?
The MCF5249CVF140 integrates USB 2.0 OTG, 10/100 Mbps Ethernet MAC (MII/RMII), dual CAN 2.0B controllers, SPI, I²C, UARTs, and an External Bus Interface (EBI). Notably, it lacks PCIe, SATA, or high-speed serial interfaces such as PCIe or Gigabit Ethernet-per the official SCF5250UM Chapter 22 specification table.
What package type and pin count does the MCF5249CVF140 use?
The MCF5249CVF140 uses a 240-pin LQFP package (28 mm × 28 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignments-including VDDIO groups, USB differential pair, CAN TX/RX, and ETH_MDC/MDIO-are documented in the SCF5250 User's Manual Appendix A and confirmed on NXP's archived product page for MCF5249.
