The NXP LPC54101J512BD64QL is a 32-bit ARM Cortex-M4 microcontroller running at 100 MHz, with 512 KB of Flash and 104 KB of RAM on a single-core die. It sits in the LPC54100 series, aimed at sensor-fusion and low-power edge processing where the M4's DSP extensions handle filter math without a separate DSP chip. The 64-LQFP package gives you 50 general-purpose I/O, a 12-channel 12-bit ADC, and serial connectivity covering I²C, SPI, and UART/USART — enough for a multi-sensor board with a display or radio link.
Supply range spans 1.62 V to 3.6 V.
On-chip ADC and serial interfaces reduce external parts
Twelve 12-bit ADC channels cover analog inputs from temperature sensors, current shunts, or potentiometers — no external converter needed for most sensor-fusion boards. The I²C, SPI, and UART/USART blocks handle digital sensors, displays, and debug links.
