Mouser now stocking ultra-low-power STM32L4 microcontrollers
Mouser Electronics, Inc. is now stocking the new STM32L4 series 32-bit microcontrollers from STMicroelectronics (ST). These ultra-low-power STM32L4 32-bit microcontrollers are based on the high-performance ARM Cortex-M4 32-bit RISC core operating at a frequency of up to 80MHz. The STM32L4 microcontrollers leverage ST's low power technologies including voltage scaling to balance power consumption with processing demand and include seven low-power management modes to give designers flexibility to optimize power consumption in a broad range of applications.
STM32L4 series microcontrollers are based on the ARM Cortex-M4 core with a floating point unit (FPU), which supports all ARM single-precision data-processing instructions and data types. Run current is a low 112uA/MHz. The devices feature ST's Adaptive Real-Time memory Accelerator (ART Accelerator), which allows zero-wait states out of the 64-bit program flash at a clock speed of 80MHz. This accelerator technology implements an innovative instruction prefetch queue and branch cache resulting in near 100 DMIPS performance.
The STM32L4 devices embed high-speed memories (up to 1Mbyte of flash memory and up to 128Kbytes of SRAM), a flexible external memory controller for static memories (for devices with packages of 100 pins and more), a quad SPI flash memories interface, and an extensive range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses, and a 32-bit multi-AHB bus matrix. The devices offer three fast 12-bit analogue-to-digital converters (ADCs), two comparators, two operational amplifiers, two digital-to-analogue converter (DAC) channels, an internal voltage reference buffer, a low-power RTC, two general-purpose 32-bit timers, two 16-bit PWM timers dedicated to motor control, seven general-purpose 16-bit timers, and two 16-bit low-power timers. The devices support four digital filters for external sigma-delta modulators. Additionally, up to 24 capacitive sensing channels are available. The devices also embed an integrated 8×40 or 4×44 LCD driver with internal step-up converter.
Mouser also stocks a complete range of STM32L4 evaluation kits including the STM32L4 Discovery Kit (STM32L476G-DISCO), STM32L4 Nucleo board (NUCLEO-L476RG) and STM32L4 Evaluation board (STM32L476G-EVAL). The STM32L4 ecosystem is completed with STM32Cube support for the STM32L4 microcontrollers.
The overall low power consumption, high performance, and DSP capability of the Cortex-M4 core, smart analogue features, and extensive digital connectivity of the new STM32L4 series make these devices suitable for smart connected and Internet-of-Things (IoT) applications, as well as a wide variety of industrial, medical, and consumer products.
