5## MCU: STM32G071RB @64MHz, 128KB FLASH, 36KB RAM
6
7The STM32G071x8/xB mainstream microcontrollers are based on high-performance Arm® Cortex®-M0+ 32-bit RISC core operating at up to 64 MHz frequency. Offering a high level of integration, they are suitable for a wide range of applications in consumer, industrial and appliance domains and ready for the Internet of Things (IoT) solutions.
8
9The devices incorporate a memory protection unit (MPU), high-speed embedded memories (up to 128 Kbytes of Flash program memory with read protection, write protection, proprietary code protection, and securable area, 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, one HDMI CEC, and four USARTs), one 12-bit ADC (2.5 MSps) with up to 19 channels, one 12-bit DAC with two channels, two fast comparators, an internal voltage reference buffer, a low-power RTC, an advanced control PWM timer running at up to double the CPU frequency, five general-purpose 16-bit timers with one running at up to double the CPU frequency, a 32-bit general-purpose timer, two basic timers, two low-power 16-bit timers, two watchdog timers, and a SysTick timer. The STM32G071x8/xB devices provide a fully integrated USB Type-C Power Delivery controller.
10The devices operate within ambient temperatures from -40 to 125°C. They can operate with supply voltages from 1.7 V to 3.6 V. Optimized dynamic consumption combined with a comprehensive set of power-saving modes, low-power timers and low-power UART, allows the design of low-power applications.
11VBAT direct battery input allows keeping RTC and backup registers powered.
12The devices come in packages with 28 to 64 pins.

85
86### 进阶使用
87
88此 BSP 默认只开启了 GPIO 和 LPUART 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：
89
901. 在 bsp 下打开 env 工具。
91
922. 输入`menuconfig`命令配置工程，配置好之后保存退出。
93
943. 输入`pkgs --update`命令更新软件包。
95
964. 输入`scons --target=mdk5/iar` 命令重新生成工程。
