Refers to a line of ARM-based microcontrollers by NXP Semiconductors.

LPC is a family of 32-bit microcontroller integrated circuits by NXP Semiconductors (formerly Philips Semiconductors). The LPC chips are grouped into related series that are based around the same 32-bit ARM processor core, such as the Cortex-M4F, Cortex-M3, Cortex-M0+, or Cortex-M0. Internally, each micro controller consists of the processor core, static RAM memory, flash memory, debugging interface, and various peripherals. The legacy LPC families were based on the 8-bit 80C51 core. As of February 2011, NXP had shipped over one billion ARM processor-based chips.
