代理新唐M252LC2AE单片机，带USB，***功耗，外设资源丰富详细介绍

低功耗和高安全性是物联网（IoT）应用的两大主要需求。NuMicro? M261 / M262 / M263 系列提供多种低功耗操作模式以满足多样的运作场景，诸如掉电模式（PD）、快速唤醒掉电模式（FWPD）、低漏电掉电模式（LLPD）、***漏电掉电模式（ULLPD）、待机掉电模式（SPD）和深度掉电模式（DPD）。 NuMicro? M261 / M262 / M263 系列亦整合了具有独立的 RTC 电源 V_BAT 引脚以实现主电源关闭而单独供电 V_BAT 的低功耗操作模式。NuMicro? M261 / M262 / M263 系列的耗电流，正常运行模式下约为 97 μA / MHz（LDO模式）和 45 μA / MHz（DC-DC模式），待机掉电模式下约为 2.8 μA，深度掉电模式下的耗电流则小于 2 μA。NuMicro? M261 / M262 / M263 系列因其低功耗、宽工作电压和待机模式下快速唤醒等特征，使其特别适合于电池供电的物联网应用。

NuMicro? M261/ M262 / M263 系列透过在微控制器中创建可信任的执行系统，进而为系统开发人员提供安全开机的功能。安全开机是一连串透过验证每一个软件身份及其完整性的流程。安全开机可以确保装置完全依照原始***所信任的软件所启动。当微控制器开机时，韧体会去检查开机程序代码的数字签名，若数字签名是正确的，则进入正常启动程序，由操作系统接续后续流程。反之，则系统会停止运行。
