The 32 KB Flash and 4 KB SRAM pair this core with enough code space for a modest protocol stack (e.g., Modbus RTU or a simple I²C sensor hub) and enough RAM for a few hundred bytes of runtime data plus a small RTOS task list. If your application needs larger lookup tables or a TCP/IP stack, you will bump into the 32 KB ceiling quickly.
28 general-purpose I/O pins.
Within the LPC1100 series, the LPC1114FHN33/201,5 is the 32 KB Flash / 4 KB SRAM variant. Pin-compatible siblings include the LPC1113 (24 KB Flash) and LPC1115 (64 KB Flash) in the same 32-HVQFN package — the difference is Flash density only; core, peripherals, and pinout are identical.
The core runs at 50 MHz maximum, which is the top speed for the LPC1100 series Cortex-M0. That gives a 20 ns instruction cycle for single-cycle operations.
