Hi, friends welcome to the new post. In this post, we will discuss the Introduction to NXP LPC Microcontrollers. LPC or low pin count is part of 32-bit controller integrated circuits made by NXP semiconductors. The LPC chips come in grouped forms of that are based on 32-bit arm processor cors, for example, Cortex-M4F, Cortex-M3, Cortex-M0+, or Cortex-M0.
The inner structure of each controller comes with processor cor, static RAM flash memory, and other components. The older LPC series comes with an Intel 8-bit 80C51 core. So let get started with Introduction to NXP LPC Microcontrollers
Introduction to NXP LPC Microcontrollers
