50 MHz Cortex-M0 in a 20-pin SOIC — what it buys you
The NXP LPC1112FD20/102529 is a 32-bit ARM Cortex-M0 microcontroller from the LPC1100L series, clocked at 50 MHz with 16 KB of Flash program memory and 4 KB of SRAM. It packs 16 general-purpose I/O lines, I²C, SPI, and UART/USART serial interfaces, plus a 5-channel 10-bit ADC — all in a 20-pin SOIC-20 surface-mount package. The part operates from 1.8 V to 3.6 V and is rated over the industrial temperature range of -40°C to 85°C, making it a fit for factory-floor sensors, motor-control feedback loops, and outdoor telecom modules where board space is tight and a full 32-bit core is needed without the overhead of a larger package.
