[原创] NXP LPC5401832位ARM MCU IoT模块解决方案

NXP公司的LPC540xx系列是基于ARM Cortex-M4的32位微控制器,采用3级流水线,具有单独本地指令和数据总线哈佛架构以及用于外设的第三总线,支持分支操作的内部预取单元,处理器工作频率180 MHz,单电源1.71V-3.6V工作,主要用在物联网(IoT).本文介绍了LPC540xx系列主要特性和优势,框图,以及IoT模块OM40007主要特性,电路图和材料清单.

The LPC540xx is a family of ARM Cortex-M4 based microcontrollers for embedded　applications featuring a rich peripheral set with very low power consumption and　enhanced debug features.

The ARM Cortex-M4 is a 32-bit core that offers system enhancements such as low power　consumption, enhanced debug features, and a high level of support block integration. The　ARM Cortex-M4 CPU incorporates a 3-stage pipeline, uses a Harvard architecture with　separate local instruction and data buses as well as a third bus for peripherals, andincludes an internal prefetch unit that supports speculative branching. The ARM　Cortex-M4 supports single-cycle digital signal processing and SIMD instructions. A　hardware floating-point processor is integrated into the core.
