 Hello, and welcome to the STM32-L4 Plus training session. This session is organized to provide you with the most important information to ensure that you can develop your application as easily as possible. You will find a technical description of all the STM32-L4 Plus modules, including peripherals and development tools organized into specific sections. System, memory, security, analog, peripherals, watchdog and timers, and ecosystem. You can browse each section separately and learn about each module in the order of your choice and at your convenience. This session allows you to search directly for a keyword and you will have a direct access to the sections covering this information. There are four major points that characterize the STM32-L4 Plus series. ST has stretched the STM32-L4 architecture to reach 150 MIPS based on its ARM Cortex-M4 core with FPU and ST-ART accelerator at 120 MHz while keeping best-in-class ultra-low-power figures. Innovation and graphics. Enhanced graphics acceleration and innovative peripherals are embedded to optimize the bomb cost. Integration and safety. Two megabytes of flash memory and 640 kilobytes of SRAM with safety and security features, smart and numerous peripherals, advanced and low-power analog circuits in packages as small as 5.2 by 5.2 millimeters. Long-term and advantageous investment. This new series of STM32 microcontrollers benefits from the pin-to-pin compatibility of the STM32 family and its ecosystem. The STM32-L4 Plus series completes the ultra-low-power family of microcontrollers developed by ST Microelectronics. The new STM32-L4 Plus series stretches the STM32-L4 technology by providing a higher performance, up to 120 MHz and more graphics capabilities and very large memory, up to 2 megabytes of flash memory and 640 kilobytes of SRAM. To simplify migration and give you all the flexibility you need, the STM32-L4 Plus is pin-to-pin compatible with the different STM32 series and opens the door to the full STM32 ecosystem. The STM32-L4 Plus is based on the same platform as the STM32-L4, which is optimized to reduce power consumption and increase flexibility, typically with its IO level kept in low-power modes, the backup SRAM in standby mode, the flexibility of wake-up sources in stop mode, the ultra-low-power consumption in shutdown mode, the separate VDD supply, the VBAT domain with charging capability, and the multi-speed internal RC oscillator programmable from 100 kHz to 48 MHz. This block diagram of the STM32-L4 Plus highlights the main sections of the microcontroller covered in this training session and their modules. The STM32-L4 Plus proposes a wide variety of features that are required to develop flexible and complex applications such as industrial control, motor control, consumer, appliance, metering, medical, gaming, printers, audio, and digital camera applications. The STM32-L4 Plus is also adapted to a wide panel of use cases. The Chromart accelerator is coupled with the large embedded SRAM, the ChromGRC round-display memory optimizer, the high throughput octo-SPI interface, and to the advanced TFT and DSI controllers, allowing you to achieve smartphone-like graphic user interfaces and a single-chip and ultra-low-power solution. The STM32-L4 Plus microcontroller includes many safety features and embeds specialized hardware for developing secured applications. Now let's get started with the training.
