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.","metaTitle":"NXP LPC54114J256UK49Z MCU, 32-Bit Dual-Core 100MHz","metaDescription":"NXP LPC54114J256UK49Z ARM Cortex-M4/M0+ dual-core MCU, 256KB Flash, 192KB RAM, 100MHz, -40 to 105°C, 49-WLCSP.
