The NXP LPC812M101FDH20FP is a 32-bit ARM Cortex-M0+ microcontroller from the LPC81xM series, clocked at 30 MHz with 16 KB of Flash and 4 KB of RAM. It packs 18 general-purpose I/O lines, plus I²C, SPI, and UART serial interfaces, all in a 20-TSSOP package. The supply range of 1.8 V to 3.6 V and an operating temperature span of -40 to 105 °C make it suited for industrial sensor nodes, motor-control feedback, or any compact control loop that needs a small footprint and moderate throughput.
30 MHz core — bus timing and throughput
The 30 MHz clock rate defines the instruction throughput for control loops and the baud-rate ceiling for the serial interfaces.
