The LPC1768 is ARM Cortex-M3 based totally microcontrollers for embedded functions that features a extreme stage of integration and low vitality consumption. The Arm Cortex-M3 is a subsequent period core that gives system enhancements akin to enhanced debug choices and the following stage of help block integration.
The LPC1768 operate at CPU frequencies of as a lot as 100 MHz. The LPC1769 operates at CPU frequencies of as a lot as 120 MHz. The Arm Cortex-M3 CPU incorporates a 3-stage pipeline and makes use of a Harvard construction with separate native instruction and knowledge buses along with a third bus for peripherals. The Arm Cortex-M3 CPU moreover incorporates an interior prefetch unit that helps speculative branching.
