Description

ST Ultra Low Power MCU: EnergyLite™ Family

The EnergyLite™ family of 8-bit (STM8L) and 32-bit (STM32L) MCUs are designed to meet

the high-performance and energy-efficiency requirements of typically battery-powered gas,

water, and heat meters in the WM-Bus scenario.

The STM8L and STM32L devices offer specific features for ultra-low power applications,

including advanced ultra-low power modes, optimized dynamic run consumption and

special safety features.

The ultra-low-power EnergyLite™ platform is based on the STMicroelectronics 130 nm

ultra-low-leakage process technology, sharing common technology, architecture and

peripherals.

The STM32 L1 series, based on ARM® Cortex™-M3, extends the ultra-low power concept

without compromising performance. More than just ultra-low-power MCUs, the STM32 L1

series offers a wide portfolio of features, memory sizes and package pin counts: from 32 to

384 Kbytes of Flash memory (with up to 48 Kbytes of RAM and 12 Kbytes of true embedded

EEPROM), and from 48 to 144 pins.

The innovative architecture (with voltage scaling and ultra-low-power MSI oscillator) adds

performance to design solutions requiring a very low power budget. The large number of

embedded peripherals (USB, LCD interface, op amp, comparator, ADC with fast on/off

mode, DAC, capacitive touch and AES), means that the STM32 L1 series is an expandable

platform able to satisfy all application requirements.

The STMicroelectronics WM-Bus application

layer is explained in this user manual.
