 Hello and welcome to the STM32L4 Series Introduction Training Session. This presentation provides information about the various product lines available in the STM32L4 Series. The STM32L4 Series is divided into product lines differentiated by key features. The product part numbers are differentiated by memory size, sub-features, and or the maximum number of peripherals as described in the following slides. STM32L476486 devices are the first products to be released, while other devices are derivatives. This is why the training slides are based primarily on STM32L476486 devices, while differences among other derivatives are often highlighted at the end of each module presentation. This table shows a list of all available product lines. The documentation provides a reference manual covering one or several product lines mentioning the differences for each product. A data sheet is available for each product reference in the table. The table lists the key features per product device. This block diagram summarizes the key features and available packages for STM32L49X4AX devices and is provided here for reference. The differences with STM32L47X48X devices are highlighted in red. STM32L49X4AX devices have the largest memory footprint and graphical peripherals like parallel camera interface and chromart accelerator for advanced graphics processing. They also include a hash processor supporting SHA256 functions, a clock recovery system, or CRS, allowing crystalless operation of the USB, an additional I2C, an additional CAN, the support of dual bank quad SPI flash memory interface to improve bandwidth, and finally the support of up to 136 GPIOs through the BGA169 package.
