It packs 256 KB of Flash and 104 KB of RAM, with 39 general-purpose I/O lines and a 12-channel 12-bit ADC. The part targets always-on sensor processing, voice activation, and low-power audio pipelines where the M0+ handles background tasks while the M4 wakes for heavy compute. Supply range of 1.62 V to 3.6 V. ## 49-WLCSP package — board integration note The 49-WLCSP (3.29×3.29 mm) is a wafer-level chip-scale package. It requires a controlled solder-paste stencil and X-ray inspection after reflow.","metaTitle":"NXP LPC54102J256UK49Z MCU, ARM Cortex-M4/M0+ Dual-Core, 100MHz","metaDescription":"NXP LPC54102J256UK49Z 32-bit MCU with 256KB Flash, 104KB RAM, 100MHz dual-core ARM Cortex-M4/M0+.
