Overview

The LPC54114J256UK49Z is a dual-core microcontroller featuring an ARM Cortex-M4 and an ARM Cortex-M0+ core, both capable of running up to 100MHz. Designed for ultra-low power efficiency, it integrates 256KB of flash and 192KB of SRAM into a compact 3.44mm x 3.44mm WLCSP49 package.

Why Choose This Part

The asymmetric dual-core architecture allows engineers to optimize the power-performance trade-off by offloading tasks to the more efficient M0+ core. Its extremely small 49-pin wafer-level chip scale package is ideal for high-density PCB designs where board real estate is at a premium.

Applications

Always-On Sensor Hubs
Utilize the Cortex-M0+ for continuous low-power sensor data collection while keeping the Cortex-M4 in sleep mode until high-performance processing is required.
Wearable Health Monitors
The tiny WLCSP footprint and low active current (8.0mA to 9.3mA at 96MHz) make it suitable for space-constrained, battery-operated medical devices.
Portable Audio Processing
Leverage the DSP instructions and FPU in the Cortex-M4 core for real-time filtering and digital signal processing in small form-factor devices.

Getting Started

Start development with the LPCXpresso54114 evaluation board (OM13089), which includes an on-board debug probe. Use the MCUXpresso SDK and IDE for comprehensive driver support and example code targeting the dual-core mailbox system.
