The NXP LPC812M101FDH16FP 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 is built for small-footprint control tasks — sensor readout, simple motor sequencing, or communication bridging — where the 14 available I/O and the I²C, SPI, and UART interfaces cover the typical peripheral set. The wide supply range from 1.8 V to 3.6 V lets it sit on a mixed-voltage board without a dedicated regulator, and the -40°C to 105°C industrial temperature rating means it can live in an outdoor telecom cabinet or a factory panel without derating concerns.
The Cortex-M0+ core runs at 30 MHz.
16 KB Flash and 4 KB RAM place this part in the entry-level tier of the LPC81xM family. The Flash holds a modest firmware image — a bootloader plus a single application loop — and the RAM supports a few hundred bytes of stack and global variables. If the firmware grows beyond 16 KB, the next density step in the same package (LPC812M101FDH16FP's sibling with 32 KB Flash) is a drop-in replacement on the same 16-TSSOP footprint.
