The NXP LPC812M101JTB16X is a 32-bit ARM Cortex-M0+ microcontroller from the LPC81xM series, clocked at 30 MHz. The supply range spans 1.8 V to 3.6 V, and the operating temperature covers –40 °C to 105 °C — an industrial-grade part suited for motor drives, outdoor telecom, and factory-automation modules where the board sees heat and cold cycles.
16 KB of Flash is the firmware budget for this part. That is enough for a single control loop with a Modbus or I²C sensor interface, a small state machine, or a serial bridge.
The 16-XSON package (3.2 × 2.5 mm) is a small, leadless surface-mount footprint — fine for compact PCBs, but requires careful solder-paste stencil design and X-ray inspection for voiding. No through-hole equivalent exists; this is a reflow-only part.
