ST has built a new architecture to reach best-in-class ultra-low-power figures thanks to its high flexibility. Moreover, the STM32L4 series shatters performance limits in the ultra-low-power world. This video is about the STM32L5, our recently announced ultra-low power microcontroller bringing a new security dimension. The STM32L5 is now in full production and all its ecosystem is available including hardware kits, software tools, firmware and all documentations of course.

Cloud 4.The library has generally separate functions for operating on 8-bit integers, bit integers, bit integer and bit floating-point values.
The library installer contains prebuilt versions of the libraries in the Lib folder. Simply include this file and link the appropriate library in the application and begin calling the library functions. Same header file will be used for floating point unit FPU variants.
By default library builds for little endian targets. It is not enabled by default when Neon is available because performances are dependent on the compiler and target architecture.
Experimental Neon versions currently do not have better performances than the scalar versions. The library is divided into a number of functions each covering a specific category: Basic math functions Fast math functions Complex math functions Filtering functions Matrix functions Transform functions Motor control functions Statistical functions Support functions Interpolation functions Support Vector Machine functions SVM Bayes classifier functions Distance functions The library has generally separate functions for operating on 8-bit integers, bit integers, bit integer and bit floating-point values.
Using the Library The library installer contains prebuilt versions of the libraries in the Lib folder. Examples The library ships with a number of examples which demonstrate how to use the library functions. Toolchain Support The library is now tested on Fast Models building with cmake.

UP - Some interesting documentations and application notes Optimizing power and performances with STM32L4 series microcontrollers AN STM32L4 ultra-low-power features overview AN A complete set of training modules that provide a technical description of all the STM32L4 features including peripherals and development tools organized into specific sections: system, memory, security, analog, peripherals, watchdog and timers and ecosystem.
Is strongly recommended to use CUBE for develop a new project. The CUBE use a new library that is not compatible with the previous one. Evaluation Board. The STM32 Nucleo board provides an affordable and flexible way for users to try out new ideas and build prototypes with any STM32 microcontroller line, choosing from the various combinations of performance, power consumption and features. It includes an embedded Ammeter which measures the MCU consumption in low power modes.
An external board can be connected thanks to extension and probing connectors. Extension headers make it possible to easily connect a daughterboard or wrapping board for a specific application. Each processor delivers an optimal trade-off for a broad embedded application range.

The approval process may take up to 48 hours.Internally, each microcontroller consists of the processor core, static RAMflash memory, debugging interface, and various peripherals. The ARM core designs have numerous configurable options, and ST chooses the individual configuration to use for each design. ST attaches their own peripherals to the core before converting the design into a silicon die.
The following tables summarize the STM32 microcontroller families. The summary for this series is:     .
The summary for this series is:   . This eliminates need for external op-amps for many applications. The built-in two-channel DAC has arbitrary waveform as well as a hardware-generated waveform sine, triangle, noise etc. All analog devices can be completely independent, or partially internally connected, meaning that one can have nearly everything that is needed for an advanced measurement and sensor interfacing system in a single chip.
The four ADCs can be simultaneously sampled making a wide range of precision analog control equipment possible. It is also possible to use a hardware scheduler for the multiplexer array, allowing good timing accuracy when sampling more than 4 channels, independent of the main processor thread.
The sampling and multiplexing trigger can be controlled from a variety of sources including timers and built-in comparators, allowing for irregular sampling intervals where needed. The op-amps inputs feature 2-to-1 analog multiplexer, allowing for a total of eight analog channels to be pre-processed using the op-amp; all the op-amp outputs can be internally connected to ADCs.
It is the most recent and fastest Cortex-M3 series. The summary for this series is:   . The F1-series has evolved over time by increasing CPU speed, size of internal memory, variety of peripherals. The summary for this series is:   . The summary for this series is:    . The STM32 G4-series is a next generation of Cortex-M4F microcontrollers aiming to replace F3 series, offering the golden mean in productivity and power efficiency, e.
STM32L4 - Implementation
