ColdFire V3 at 240 MHz — the speed ceiling for this ROMless MCU
The MCF53011CQT240 is an NXP ColdFire V3 32-bit single-core MCU clocked at 240 MHz, with 128K x 8 of on-chip RAM and no internal program memory — all code executes from external memory via the EBI/EMI interface. The 240 MHz core speed is the headline performance spec for this part — it sets the instruction throughput ceiling for real-time control loops, protocol stacks, and data processing. The ColdFire V3 architecture sits between the V2 (120 MHz in the SCF5250) and V4 (180 MHz in the MCF54450) in the MCF family, offering a balance of performance and power for mid-range embedded designs.
Connectivity and peripheral set — Ethernet and USB OTG on a ROMless part
On-chip DMA and PWM peripherals offload the core for motor-control loops and high-speed data transfers, while the WDT provides system-level fault recovery in unattended operation. With 61 general-purpose I/O lines in a 208-pin TQFP package, the part supports medium-complexity control panels or human-machine interfaces with room for parallel buses and discrete signals.
Active lifecycle and compliance status
ROHS3 compliant, with no exempted substances — the part meets the latest EU RoHS directive without supply-chain restrictions tied to exemption phase-outs.
