The NXP LPC54606J256BD100551 is a 32-bit ARM Cortex-M4 microcontroller from the LPC546xx series, clocked at 180 MHz. The 100-pin LQFP package (14x14 mm body) exposes 64 general-purpose I/Os and a 12-channel 12-bit ADC.
180 MHz Cortex-M4 — what it means for throughput
The 180 MHz core speed places this MCU in the mid-to-upper tier of Cortex-M4 parts. At this clock, single-cycle multiply-accumulate operations and hardware DSP extensions handle real-time control loops, audio processing, or protocol stacks without an external co-processor. The 136 KB of SRAM gives enough headroom for double-buffered Ethernet frames or a modest RTOS heap, while the 16 KB EEPROM emulation space holds calibration constants and configuration parameters that survive a firmware update.
The 100-LQFP package has a 14x14 mm body.
