感谢管理“Seven”，因为工作原因不能实地参加STM32的深圳会议，在seven管理的热心组织下，通过线上直播让我了解了这一次的技术盛况，从开始的技术讲解到后期的竞赛直播，各个阶段都充分体现了专业性、素养性。不但使我学习了知识，同时也更好的了解了STM32的相关技术和使用场景，对我个人是一个很大的提升，在此对ST公司和seven管理再次表示感谢。

描述
& a- Y- K7 G2 X0 z  v$ HThe STM32G474xB/xC/xE devices are based on the high-performance Arm® Cortex®-M4 32-bit RISC core. They operate at a frequency of up to 170 MHz. The Cortex-M4 core features a single-precision floating-point unit (FPU), which supports all the Arm single-precision data-processing instructions and all the data types. It also implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) which enhances the application’s security.
These devices embed high-speed memories (512 Kbytes of Flash memory, and 128 Kbytes of SRAM), a flexible external memory controller (FSMC) for static memories (for devices with packages of 100 pins and more), a Quad SPI Flash memory interface, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses and a 32-bit multi-AHB bus matrix.
The devices also embed several protection mechanisms for embedded Flash memory and SRAM: readout protection, write protection, securable memory area and proprietary code readout protection.
