<h1 id="purpose">Purpose</h1>
<p>STM32G4 series will serve all applications where <strong>advanced and/or rich analog</strong> peripheral set is required :</p>
<ul>
<li><p>ADC with HW oversampling (16-bit resolution, Offset &amp; Gain compensation)</p></li>
<li><p>High Resolution Timer</p></li>
<li><p>Enhanced Timer functions (encoder modes)</p></li>
<li><p>Mathematical accelerator (Trigonometric and Filtering functions)</p></li>
<li><p>USB typeC, with Power Delivery</p></li>
</ul>
<p><strong>STM32Cube is an STMicroelectronics original initiative to ease developers life by reducing development efforts, time and cost.</mark></strong></p>
<p>STM32Cube covers STM32 portfolio.</p>
<p>STM32Cube Version 1.x includes:</p>
<ul>
<li>The STM32CubeMX, a graphical software configuration tool that allows to generate C initialization code using graphical wizards.</li>
<li>A comprehensive embedded software platform, delivered per series (such as <a href="https://www.st.com/en/product/stm32cubeg4">STM32CubeG4</a> for STM32G4 series)
<ul>
<li>The STM32Cube HAL, an STM32 abstraction layer embedded software, ensuring maximized portability across STM32 portfolio.</li>
<li>Low-layer APIs (LL) offering a fast light-weight expert-oriented layer which is closer to the hardware than the HAL.</li>
<li>A consistent set of middleware components such as USB Device, USB Power Delivery, FAT file system and RTOS.</li>
<li>All embedded software utilities, delivered with a full set of examples.</li>
</ul></li>
</ul>
<p>The STM32Cube firmware solution offers a straightforward API with a modular architecture, making it simple to fine tune custom applications and scalable to fit most requirements.</p>

<p>Maintenance release of STM32CubeG4 (STM32Cube for STM32G4 Series) Firmware package supporting STM32G431xx/41xx/71xx devices, STM32G473xx/<strong>83xx</strong> devices and STM32G474xx/84xx devices.</p>
<p>A Discovery kit, B-G474E-DPOW, is introduced in this release to enable demonstration of Buck and Boost in voltage mode, High brightness RGB LED control and USB audio streaming.</p>
<p>In the STM32CubeG4 MCU Package, examples and applications projects are generated with the STM32CubeMX tool to initialize the system, peripherals and middleware stacks. User can open the provided ioc file in STM32CubeMX to modify the settings, add additional peripherals and/or middleware, to build his final application.</p>
<p>Demonstrations binaries are no more delivered within the STM32CubeG4 MCU package. They are available for download, in addition to their required media files if any, in a standalone package accessible through each hardware board official webpage. Please refer to the corresponding demonstration binary readme.txt to get webpage for each board.</p>
<h2 id="contents-4">Contents</h2>
