16 KB Flash is sized for small control loops, bootloader-plus-application firmware, or a single Modbus RTU stack. The 2 KB SRAM handles a few dozen register variables and a modest UART buffer. With 19 I/Os in a 24-pin package, the pinout is dense — plan for shared-function conflicts if you need both the full ADC channel count and all three serial interfaces simultaneously.
Within the LPC1100L series, higher-density variants (e.g., LPC1114 with 32 KB Flash) share the same 24-HVQFN footprint and pinout, offering a drop-in upgrade path without PCB changes.
The core runs at 50 MHz, which determines the maximum throughput for its I²C, SPI, and UART interfaces.
