Finding just the right component is a struggle engineers face on a regular basis. STMicroelectronics and Arrow can help you cut down on your search time – finding everything you need for your next embedded system, whether it’s a small project or a full-featured platform. ST sensors and interface and protection circuits add critical functionalities to new technologies, while their microcontrollers accommodate control environments. In addition, you’ll also find dynamic power converters that serve as excellent solutions for more efficient power management systems as well as analog and radio components for signal conditioning and connectivity that reliably communicate data back to a remote environment.
Superior MCU Solutions Based on ARM® Cortex-M
ST MCUs cover a range of performance specifications to meet the needs of your individual applications. Among their dynamic product lineup, you’ll find everything from the STM8L (8-bit proprietary core) up to the STM32L4 (ARM® Cortex®-M4), along with the STM32L0 (ARM® Cortex®-M0+) and the STM32L1 (ARM® Cortex®-M3). In fact, the STM32 is among the industry’s broadest MCU families, with 10 series and more than 40 product lines.
Some of the MCU products of particular note include the latest STM32F7 series based on ARM® Cortex®-M7 core with maximum clock speed of 216 MHz and up to 2 MB of Flash. STM32L4 devices deliver both high core performance and outstanding ultra-low-power efficiency. The EEMBC®[1] CoreMark® score of 273 outperforms other ultra-low-power cores, while the ULPBench™ score of 245 confirms greater energy efficiency. Active-mode current of just 36µA/MHz enables longer runtime on small batteries and extends scope to create energy-neutral products powered from ambient sources. The STM32L475VGT6, for example (which can be found on the SensorTile development kit) has up to 1 MB of Flash and up to 128 KB of SRAM.
