<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 & 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>

</figure>
<p>The HAL (Hardware Abstraction Layer) and LL (Low Layers) drivers provided within this package support the <strong>STM32G431xx/41xx</strong>, <strong>STM32G471xx</strong>, <strong>STM32G473xx/83xx</strong> and <strong>STM32G474xx/84xx</strong> lines.</p>
<p>The HAL and LL drivers provided within this package are compliant with MISRA-C®:2012 guidelines, and have been reviewed with a static analysis tool to eliminate possible run-time errors. Reports are available on demand.</p>
<p>For <strong>quick getting started with the STM32CubeG4 firmware package</strong>, refer to <a href="Documentation/STM32CubeG4GettingStarted.pdf">UM2492</a> and you can download firmware updates and all the latest documentation from <a href="http://www.st.com/stm32cubefw">www.st.com/stm32cubefw</a></p>
