High-performance STM32 L4 series ARM Cortex-M4 based microcontrollers from stock

RS Components has announced stock availability of the STMicroelectronics STM32 L4 series of ultra low-power microcontrollers (MCUs), which offer a novel blend of high memory size with ultra-low-power and CPU performance for a variety of applications. The highly-flexible architecture developed by ST for the series provides an ultra-low-power solution for MCUs, enabling the STM32 L4 MCUs to score a world-record 176.7 in the standardised EEMBC ULPBench tests, which compare the efficiency of ultra-low-power MCUs. The STM32 L4 series delivers 100 DMIPS based on its ARM Cortex-M4 processor core with FPU (Floating-Point Unit) and ST's ART (Adaptive Real-Time) Accelerator running at 80MHz. The STM32 L4 MCUs offer dynamic voltage scaling to balance power consumption with processing demand, as well as safety and security features and a wide variety of low-power peripherals, including UART and timers available in stop mode, and advanced and low-power analogue peripherals such as op amps, comparators and 12-bit DACs and 16-bit ADCs. Available in two variations - the STM32L476 (USB, LCD) and STM32L486 (USB, LCD, AES) - the STM32L4 series is pin-to-pin compatible with the whole STM32 range, thereby simplifying migration to provide flexibility and expansion requirements, says the company.
