Rutronik includes new Family of Microcontrollers from STMicroelectronics in its program

SEP14-RUT-STM32L0STMicroelectronics presents its new STM32L0 ultra-low-power series, featuring a 32MHz ARM® Cortex™ M0+ processor core, a 12-bit Analog-to-Digital Converter (ADC) and a USB FS 2.0 crystal-less solution. The series with lower system cost and greater convenience for end-users is available at distributor Rutronik as of now.

With the ADC consuming just 40?A at a conversion speed of 100ksps, rising to just 200?A at 1.14Msps, in combination with very good power efficiency of both the processor core and the ultra-low-power peripherals, applications such as fitness trackers and domestic smoke detectors powered by non-rechargeable batteries require less frequent replacements, saving costs and the environmental burden of spent batteries. They allow designs with smaller batteries, thus reducing the size and costs of products such as portable health and fitness products. The devices are fabricated in proprietary CMOS technology that offers both embedded EEPROM, as well as the industry’s smallest variation in power consumption over a temperature range of 25° up to 125°C. Thus, STM32L0 microcontrollers are particularly suitable for industrial sensor applications relying on batteries or energy harvesting.

The STM32L0 series is available in three lines: Access line, USB line, and USB/LCD line. Common features of all of them include greater power consumption in several modes including 139?A/MHz at 32MHz, 87?A/MHz using an optimized mode, and 400nA in stop mode with full RAM retention and a 3.5?s wake-up time. The series also provides up to 64KB of Flash memory, up to 8KB of SRAM, and 2KB of embedded true EEPROM. A built-in hardware oversampling capability enables 16-bit ADC resolution.
