LPC1347FBD64: Entry-level 32-bit Microcontroller (MCU) based on Arm^® Cortex^®-M3 Core

Overview

The LPC1347FBD64 is an Arm Cortex-M3 based microcontroller for embedded applications featuring a high level of integration and low power consumption. The Arm Cortex-M3 is a next generation core that offers system enhancements such as enhanced debug features and a higher level of support block integration. The LPC1347FBD64 operates at CPU frequencies of up to 72 MHz. The Arm Cortex-M3 CPU incorporates a 3-stage pipeline and uses a Harvard architecture with separate local instruction and data buses as well as a third bus for peripherals. The Arm Cortex-M3 CPU also includes an internal prefetch unit that supports speculative branching.
