8 KB of Flash and 2 KB of RAM set the firmware ceiling. If your next spin needs more room, the LPC1100L family scales up to 32 KB Flash and 8 KB RAM in the same HVQFN footprint — the pinout stays compatible, so you can swap without a board respin.
Within the LPC1100L family, higher-density variants such as the LPC1112 (16 KB Flash) or LPC1114 (32 KB Flash) share the same 32-HVQFN pinout. They are drop-in replacements on the same board layout, offering more firmware space without a PCB change.
The core runs at 50 MHz. That is the maximum clock for the ARM Cortex-M0 in this part, set by the internal oscillator or an external crystal.
