Dual-core MCU for sensor fusion and audio processing
The NXP LPC54114J256UK49Z is a 32-bit dual-core microcontroller built around an ARM Cortex-M4 and a Cortex-M0+ core, both running at 100 MHz. The M4 handles compute-intensive tasks like FFT or sensor fusion algorithms while the M0+ offloads housekeeping, I/O polling, and low-power background routines — partitioning the workload without a second chip.
100 MHz — what it buys you on the bus
100 MHz core speed on the Cortex-M4 side. The M0+ companion core runs the same clock.
Supply range of 1.62 V to 3.6 V.
