The NXP LPC1114FHI33/303K is a 32-bit ARM Cortex-M0 MCU from the LPC1100XL series, clocked at 50 MHz with 32 KB Flash and 8 KB RAM. It carries 28 general-purpose I/O lines, I²C, SPI, and UART/USART connectivity, plus an 8-channel 10-bit SAR ADC. The 1.8 V to 3.6 V supply range and -40°C to 85°C rating make it a fit for industrial control panels, sensor nodes, and embedded I/O modules where the processor needs to handle a few serial links and a handful of analog inputs without breaking the power budget.
50 MHz core — timing headroom for serial buses
The 8 KB RAM is tight for buffered protocol stacks; keep the firmware lean and the interrupt service routines short to avoid stack overflow.
Active lifecycle — no end-of-line pressure
NXP lists this part as Active. No last-time-buy window, no successor to track. For a multi-year production run the supply outlook is stable through franchised and independent channels alike.
