 Hello, and welcome to this presentation of the STM32L0 series of Ultralow Power Microcontrollers with the 32-bit ARM Cortex M0 Plus Core. The STM32L0 series is part of ST's 10-year Product Longevity Commitment Program for STM32 and STM8 microcontrollers. To break ultralow power challenges, battery-powered applications need four key ingredients. Low consumption. Ultralow power applications need to use devices with the lowest power consumption. The STM32L0 is based on ST's own ultralow power process technology and it provides record-breaking low power performance. Energy efficiency. The level of efficiency is one of the key elements that contribute to the success of ultralow power applications. From the heart of its architecture right to the end of its peripherals, the STM32L0 comes with innovative features allowing to conserve any small amount of energy and to reach outstanding energy efficiency. Maximum integration. On top of low power, another key element is the need of high integration. STM32L0 is available in tiny packages with large memory size, various set of peripherals, and full security features. Cost savings. Last but not least, a successful solution has to be cost-effective. The STM32L0 has a competitive portfolio and comes with a free software development ecosystem. The STM32L0 series offers seven different power modes to fit any power-sensitive application profile. For applications that spend most of their time sleeping, the STM32L0 offers dedicated stop and standby modes. Standby mode is designed to save the maximum amount of energy, shutting off all that is not needed. The wake-up time from standby to active mode is only 50 microseconds via a reset or by one of the two wake-up pins. Stop mode is very flexible to perfectly fit any application. With the RTC enabled, providing time counting, sub-second counting, auto wake-up, calibration and calendar features, stop mode consumes only 5.4 microamps under the highest temperature condition at 125 degrees Celsius. STM32L0 devices can wake up from stop to active mode using up to 16 wake-up lines in only 3.5 microseconds from RAM or 5 microseconds from flash memory. To optimize power consumption while sleeping, the STM32L0 provides a low-power sleep mode that consumes only 3.6 microamps with the flash memory off and 14.5 microamps keeping the flash memory on at ambient temperature. For applications that require very low active current versus efficiency, here again, the STM32L answers the call with its low-power run mode, which consumes as little as 18.5 microamps. At full speed at 32 MHz, the STM32L0 sleep mode consumes only 37 microamps per MHz and active mode is optimized to consume just 139 microamps per MHz at full speed. On top of that, the STM32L0 is, in its category, the undisputed market champion at 125 degrees Celsius with the lowest current consumption and the only one sustaining such high temperature in the industry. This graph shows the position of the STM32L0 series platform versus comparable competitor devices. It shows the evolution of the lowest power mode with RAM retention versus the temperature and the device's temperature limitations. The result is clear. The STM32L0 is the only device functional up to plus 125 degrees Celsius with the lowest current consumption. Healthcare applications such as fitness trackers, blood pressure gauges, or glucose meters need to combine rich analog features together with an optimized battery lifetime and competitive solution. The STM32L0 is a perfect match to answer healthcare needs. The STM32L0 comes with rich analog features. Its 12-bit ADC is optimized to consume as little as possible. It can operate under a low voltage going down to 1.65 volts and in terms of current consumption, at 100 kilo samples per second it draws only 48 microamps from the power source. The ADC is not only able to reduce the energy cost to acquire analog signals it can also achieve high resolution up to 16 bits by hardware oversampling. To complete the analog feature set, the STM32L0 integrates a 12-bit DAC and two built-in comparators. Moreover, the STM32L0 is able to minimize the inrush current that protects the battery and maximizes its lifetime. The STM32L0 is the right device to meet the challenges of applications such as IoT, remote controllers, and accessories. Such applications are very sensitive to bomb cost, PCB size, and battery lifetime maximization. To reduce power consumption, the STM32L0 series hosts a low-power UART with wake-up capability as well as a low-power 16-bit time counter. Thanks to the ultra-low power timer, users can keep counting time in stop mode using a power consumption of only 440 nanoamps with full RAM retention. To help customers find the best design in regards to bomb cost, the STM32L0 series offers a built-in LCD driver and a USB 2.0 crystal-less interface that supports battery-charging detection and link power management features. No compromise on CPU speed, the STM32L0 offers a wide-voltage range with full speed capability. Therefore, no need to increase VDD to run at high speed. Now, ultra-low power is synonymous with high-processing speed. The STM32L0 shows high integration with large memory size with up to 192 kilobytes of dual-bank flash memory and 20 kilobytes of SRAM. Moreover, it provides a full security feature set, including hardware encryption capability, flash protection, true random number generator and a 96-bit unique ID. These hardware features combined with the STM32 ecosystem makes the STM32L0 ready to be class B compliant. These MCUs are available in small sizes down to 2x2 mm for WLCSP packages. The STM32L0 series is available in three different lines, which share a common architecture with five clock sources, three internal and two external, USART, SPI and I2C communication peripherals, DMA, 12 or 16-bit ADCs, comparators and temperature sensors. The STM32L0X1 is the access line. It is designed to answer the needs for entry-level ultra-low power applications. The offer goes from 14 up to 100 pins and from 8 up to 192 kilobytes of dual-bank flash memory with 20 kilobytes of SRAM and 6 kilobytes of EEPROM. The STM32L0X2 USB line extends the access line and features a 12-bit DAC, 16 capacitive touch keys, a true random number generator and USB 2.0 FS crystal-less options. The STM32L0X3 USB and LCD line extends the USB line by offering a built-in LCD driver. The three STM32L0 lines offer optional 128-bit AES hardware encryption if needed. The STM32L0 series includes more than 100 part numbers, providing a large choice of memory sizes, pin counts and packages. Thanks to this large product portfolio, customers can find the right product tailored to their needs. With the unit price as low as a single 8-bit device, switching to a 32-bit one has never been so easy. A 32-bit performance at an 8-bit price without compromise on power consumption and robustness. That's the deal. The STM32L0 is a great investment. It benefits from pen-to-pen compatibility across the STM32 family. The STM32 portfolio offers an extraordinary variety of compatible microcontrollers based on ARM Cortex-M cores. M0, M0+, M3, M4 and M7, giving developers flexibility to find the perfect STM32MCU for their applications. The STM32L0 series offers three different kinds of boards to evaluate, discover and play with the series. While the evaluation board will let you study in-depth the STM32L0 platform, the Discovery Kit, with its e-paper display, is more application-oriented. The STM32Nucleo board with its Arduino connector is dedicated more for fast prototyping. The STM32Nucleo board is embed-compliant like any other STM32Nucleo board. Thanks to STM32CubeMX, users can optimize the layout, configure the MCU and evaluate its power consumption in their application. The STM32CubeMX solution also facilitates the migration from an STM32L0 to any other STM32MCU series. To complete this offer, the STM32L0 series is supported by free IDE solutions such as Keele, AC6 system workbench and KuCox. The highly affordable STM32Nucleo boards allow anyone to try out new ideas and to quickly create prototypes with any STM32MCU. Four Nucleo boards based on STM32L0 microcontrollers are available. STM32Nucleo boards can easily be extended with a large number of specialized application hardware add-ons, Arduino, Uno, Rev3 and ST Morpho connectors on Nucleo64, Arduino Nano connectors on Nucleo32.
