ColdFire V4 at 250 MHz — core performance and on-chip resources
The MCF54410CMF250 is a 32-bit single-core ColdFire V4 microcontroller running at 250 MHz. That clock rate sets the instruction throughput ceiling in real-time control loops — the CMF250 suffix confirms the speed grade, so a BOM calling for the 250 MHz variant picks this exact part, not a lower-bin sibling. On-chip SRAM is 64K x 8 (64 KB), which is the scratchpad for time-critical data — interrupt vectors, stack, and small buffers live here without DRAM latency. The core voltage rail is tight at 1.14 V to 1.32 V, so the board's 1.2 V regulator needs to hold regulation within this window under load steps from the core. The 196-MAPBGA (15x15 mm) package demands a controlled reflow profile and X-ray inspection for hidden solder joints under the BGA body.
Peripheral set — connectivity for a networked control node
The MCF54410CMF250 integrates Ethernet MAC, USB OTG, CANbus, I²C, SPI, SSI, UART/USART, and a SmartCard interface. This makes it a single-chip host for an industrial gateway or a motor-drive controller that needs both a fieldbus port and a local debug UART. With 48 general-purpose I/O lines and internal DMA, PWM, and watchdog timer peripherals, the part can handle sensor polling, pulse generation, and supervisory monitoring without external CPLD or glue logic in many designs. The internal oscillator option reduces external component count — a clean 1.2 V rail and decoupling on the BGA supply balls are the main layout constraints.
