| 9 | +The devices incorporate a memory protection unit (MPU), high-speed embedded memories (128 Kbytes of Flash program memory with read protection, write protection, and 36 Kbytes of SRAM), DMA and an extensive range of system functions, enhanced I/Os and peripherals. The devices offer standard communication interfaces (two I2Cs, two SPIs / one I2S, and four USARTs), one 12-bit ADC (2.5 MSps) with up to 19 channels, a low-power RTC, an advanced control PWM timer, five general-purpose 16-bit timers, two basic timers, two watchdog timers, and a SysTick timer. |
| 10 | +The devices operate within ambient temperatures from -40 to 85°C. They can operate with supply voltages from 2.0 V to 3.6 V. Optimized dynamic consumption combined with a comprehensive set of power-saving modes allows the design of low-power applications. |
| 11 | +VBAT direct battery input allows keeping RTC and backup registers powered. |
| 12 | +The devices come in packages with 32 to 64 pins. |

66 | | -### 快速上手 |
67 | | - |
68 | | -本 BSP 为开发者提供 MDK5 和 IAR 工程，并且支持 GCC 开发环境。下面以 MDK5 开发环境为例，介绍如何将系统运行起来。 |
69 | | - |
70 | | -#### 硬件连接 |
71 | | - |
72 | | -使用数据线连接开发板到 PC，打开电源开关。 |
73 | | - |
74 | | -#### 编译下载 |
75 | | - |
76 | | -双击 project.uvprojx 文件，打开 MDK5 工程，编译并下载程序到开发板。 |
77 | | - |
78 | | -> 将工程使用的仿真器设置为ST-Link并安装仿真器好驱动程序以后，将开发板连接到PC，点击下载按钮即可下载程序到开发板。 |
79 | | -
|
80 | | -#### 运行结果 |
81 | | - |
82 | | -下载程序成功之后，系统会自动运行。 |
83 | | - |
84 | | -连接开发板对应串口到 PC , 在终端工具里打开相应的串口（115200-8-1-N），复位设备后，可以看到 RT-Thread 的输出信息: |

94 | | -### 进阶使用 |
95 | | - |
96 | | -此 BSP 默认只开启了 GPIO 和 UART 的功能，如果需使用 SPI，I2C 等更多高级功能，需要利用 ENV 工具对BSP 进行配置，步骤如下： |
97 | | - |
98 | | -1. 在 bsp 下打开 env 工具。 |
99 | | - |
100 | | -2. 输入`menuconfig`命令配置工程，配置好之后保存退出。 |
101 | | - |
102 | | -3. 输入`pkgs --update`命令更新软件包。 |
103 | | - |
104 | | -4. 输入`scons --target=mdk5/iar` 命令重新生成工程。 |
