MCU之Microchip PIC16F17146 Curiosity NANO Evaluation Kit评测报告

对比完 RISC(Proprietary) 与 RISC-V(Open Source),来点 Microchip 的 PIC16F17146 Curiosity Nano(Revision 4 has PIC16F17146 rev B2) Evaluation Kit的实测：
一、综述
这块板是多层PCB设计，大量使用SMD(Surface Mounted Devices), 使整板轻而小(51mm20mm5mm，包括按钮开关高度), 整体才大拇指大小。既可独立使用也可对外输出或作为模块快捷组合，板载最重要的有:

  1. Debugger ATSAMD21E18A-U: 32bit MCU, ARM® Cortex series, come from Microchip;
  2. on board MCU PIC16F17146-6N: 8bit MCU, PIC® series, comefrom Microchip;
  3. Micro USB对外Interfere，如果是最新的 Type-C 就更好了;
  4. 32.768KHz的晶体震荡器 VMK3-9001-32K7680000TR ;
  5. 两个板载LED:
    靠近Micro USB接头的是Power/Status 电源与状态指示LED
    靠近User Switch的是User LED(LED0)只是对BUS/板载PIC MCU的Power/Status
  6. 一枚机械按钮常开状态的开关 User Switch, 对Target Regulator的供电管理 5V Power BUS 和 PIC MCU的供电进行控制7. 带防短路电流检测与保护功能，以及，因此可以放心的使用。
  7. VBUS Output Pin 有对外供电总线输出功能(4.4V-5.25V, 1A电流能力, 带PTC保险丝)
  8. Debugger通过调整PCB线路，不仅可以对板载 PIC16F17146 MCU还可以对外部设备进行Programming与Debugging.
  9. Pin-Headers 排针方便插接Microchip的积木式组合Base Board基板。

Microchip官方有提供本板的User Guide应用指导文档、 Schematic电路图、Assembly Drawing组装图、Pinout Mapping对外端口映射图，以及其它文档与资源。

总体上定位清晰、目标明确、有系统设计思想、兼容搭积木模组化、全面、美观、实用、多功能、可扩展、节能、成本有管理、精心选用材料(大多数Microchip自家的系列)、配套软硬件齐全、文档完善。
体现Microchip公司总体的战略、文化、生态建设、用户社群与市场理念、公司管理与组织协作、软硬件系统设计、工程实施、生产制造，全球交付等的落实。

二、Board对两块MCU的设计对比:
Debugger用的 32bit ATSAMD21E18A-U 计算性能、存储能力、GPIO数 要比 on board 8bit PIC16F17146-6N 强太多，只是 PIC16F17146-6N 功能更全，而且是本Evaluation Kit设计的主角而已。
实际这完全是一块板载32bit ARM® Cortex RISC MCU 与 8bit PIC® MCU都可以同时独立使用的开发板！

因为 Debugger是一枚更强大的MCU，可以 Update firmware, 而且 通过 线路调整(剪断板背面的Programming and Debugging Connections to Debugger GPIO straps 就可以独立对外)，不仅可以对 on board PIC16F17146-6N MCU 还可以对外部的 MCU 进行 Programming 与 debugging，成为一块独立的 烧录器 与 编程器。

三、Microchip官方更是提供商业级的:
User Guide/Mannual and other document文档；
商业级用户技术支持
Altium 的PCB电路设计文件，以及GITHUB hosted 的 多个示范应用 Source Code 都有
完整的全套 MPLAB® 软体：开发X IDE、商业编译器XC Compilers、MCC(Code Configurator, 自动生成驱动与硬件抽象层C Source文件)、调试Debugger(例如MPLAB® PICkit™ series)、可视化操控的 Data Visualizer、MPLAB Discover社会化/社交化项目协作的可以方便找到 collateral 和 example projects …
Microchip Xpress云端快速的开放环境www.mplab-xpresside.microchip.com/；
Microchip的 Sample Store在线申请 Sample；
直营的 Microchip 在线网上商店，全球可以提交订单采购。

Microchip官方甚至连用 Altium 设计的PCB电路设计项目文件和BOM物料单，以及GITHUB hosted 的 多个示范应用都有.
