Product details

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.

Frequently asked questions

What is the closest pin-compatible alternative to LPC54114J256UK49Z?

NXP offers multiple density variants within the LPC54100 family (e.g., 512 KB Flash / 256 KB RAM versions in the same WLCSP49 footprint). The base product number LPC54114 identifies this specific Flash/RAM configuration; moving up or down in density keeps pin compatibility across the family.

What is LPC54114J256UK49Z's listed speed?

The core speed is 100 MHz for both the Cortex-M4 and Cortex-M0+ processors.

What compliance documentation does NXP provide for LPC54114J256UK49Z?

NXP provides ROHS3 compliance certification. No UL or IEC documentation is listed in the standard product data; for specific regulatory needs, request documentation at quote time.
